+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,

+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+          include this file. This file now includes the various basicop2
+          functions' header files instead of defining the function
+          prototypes.

+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description: Finished first pass of optimization.
+
+ Description: Made changes based on review comments.
+
+ Description: Made input to Chebps_Wrapper consistent with that of Chebps.
+
+ Description: Replaced current Pseudo-code with the UMTS code version 3.2.0.
+              Updated coding template.
+
+ Description: Replaced basic_op.h and oper_32b.h with the header files of the
+              math functions used by the file.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Used "-" operator instead of calling sub function in the
+                 az_lsp() code.
+              2. Copied detailed function description of az_lsp from the
+                 header file.
+              3. Modified local variable definition to one per line.
+              4. Used NC in the definition of f1 and f2 arrays.
+              5. Added curly brackets in the IF statement.
+
+ Description: Changed function interface to pass in a pointer to overflow
+              flag into the function instead of using a global flag. Removed
+              inclusion of unneeded header files.
+
+ Description:  For Chebps() and Az_lsp()
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation.
+              4. Eliminated not needed variables
+              5. Eliminated if-else checks for saturation

+     f2[i] = a[i] - a[11-i] + f2[i-1] ;   i=1,...,5
+
+ The roots of F1(z) and F2(z) are found using Chebyshev polynomial evaluation.
+ The polynomials are evaluated at 60 points regularly spaced in the
+ frequency domain. The sign change interval is subdivided 4 times to better
+ track the root. The LSPs are found in the cosine domain [1,-1].
+
+ If less than 10 roots are found, the LSPs from the past frame are used.

+ FUNCTION DESCRIPTION
+
+ This function is a fractional integer division of two 32 bit numbers, the
+ numerator L_num and the denominator L_denom. The denominator is formed by
+ combining denom_hi and denom_lo. Note that denom_hi is a normalized numbers.
+ The numerator and denominator must be positive and the numerator must be
+ less than the denominator.
+
+ The division is done as follows:
+ 1. Find 1/L_denom by first approximating: approx = 1 / denom_hi.
+ 2. 1/L_denom = approx * (2.0 - L_denom * approx ).
+ 3. result = L_num * (1/L_denom).

+ REVISION HISTORY
+
+ Description: Put file into template.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Replaced basic_op.h with the header files of the math functions
+              used in the file.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Defined one local variable per line.
+              2. Used "&=", ">>=", and "+=" in the code.
+
+ Description: Updated template. Changed function interface to pass in a
+              pointer to overflow flag into the function instead of using a
+              global flag.
+
+ Description: Removed inclusion of inv_sqrt.tab file. Changed array name
+              from "table" to "inv_sqrt_tbl"
+
+ Description: Removed math operations that were not needed as functions,
+             this because the numbers themselves will not saturate the
+             operators, so there is not need to check for saturation.
+
+ Description: Updated copyrigth year, according to code review comments.
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations

+ FUNCTION DESCRIPTION
+
+ This function computes 1/sqrt(L_x), where L_x is positive.
+ If L_x is negative or zero, the result is 1 (3fff ffff).
+
+ The function 1/sqrt(L_x) is approximated by a table and linear
+ interpolation. The inverse square root is computed using the
+ following steps:
+    1- Normalization of L_x.
+    2- If (30-exponent) is even then shift right once.
+    3- exponent = (30-exponent)/2  +1
+    4- i = bit25-b31 of L_x;  16<=i<=63  because of normalization.
+    5- a = bit10-b24
+    6- i -=16
+    7- L_y = table[i]<<16 - (table[i] - table[i+1]) * a * 2
+    8- L_y >>= exponent

+------------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    L_var1 = 32 bit long signed integer (Word32 ) whose value falls
+             in the range : 0x8000 0000 <= L_var1 <= 0x7fff ffff.
+    var2 = 16 bit short signed integer (Word16) whose value falls in
+           the range : 0xffff 8000 <= var2 <= 0x0000 7fff.
+
+    pOverflow = pointer to overflow (Flag)
+
+ Outputs:
+    pOverflow -> 1 if the 32 bit shift operation resulted in overflow
+
+ Returns:
+    result = Shifted result w/ rounding (Word32)
+
+ Global Variables Used:
+    None
+
+ Local Variables Needed:
+    None
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function arithmetically shifts the 32 bit input L_var1 right var2
+ positions with rounding. If var2 is negative, the function
+ arithmetically shifts L_var1 left by -var2 and zero fills the -var2 LSB of
+ the result. The result is saturated in case of underflows or overflows, i.e.,
+
+ - If var2 is greater than zero :
+    if (L_sub(L_shl(L_shr(L_var1,var2),1),L_shr(L_var1,sub(var2,1))))
+    is equal to zero
+    then
+        L_shr_r(L_var1,var2) = L_shr(L_var1,var2)
+    else
+        L_shr_r(L_var1,var2) = L_add(L_shr(L_var1,var2),1)
+ - If var2 is less than or equal to zero :
+    L_shr_r(L_var1,var2) = L_shr(L_var1,var2).

+ MODULE DESCRIPTION
+
+ This file contains functions that convert line spectral pairs (LSP) to
+ linear predictive (LP) coefficients (filter order = 10). The functions
+ included in this file include Get_lsp_pol, which finds the coefficients of
+ F1(z) and F2(z), and Lsp_Az, which converts LSP to LPC by multiplying
+ F1(z) by 1+z^(-1) and F2(z) by 1-z^(-1), then calculating A(z) = (F1(z) +
+ F2(z))/2.

+ FUNCTION DESCRIPTION
+
+ This function finds the polynomial F1(z) or F2(z) from the LSPs. If the LSP
+ vector is passed at address 0, F1(z) is computed and if it is passed at
+ address 1, F2(z) is computed.
+
+ This is performed by expanding the product polynomials:
+
+    F1(z) =   product   ( 1 - 2 lsp[i] z^-1 + z^-2 )
+        i=0,2,4,6,8
+    F2(z) =   product   ( 1 - 2 lsp[i] z^-1 + z^-2 )
+        i=1,3,5,7,9
+
+ where lsp[] is the LSP vector in the cosine domain.
+
+ The expansion is performed using the following recursion:
+
+    f[0] = 1
+    b = -2.0 * lsp[0]
+    f[1] = b
+    for i=2 to 5 do
+        b = -2.0 * lsp[2*i-2];
+        for j=i-1 down to 2 do
+            f[j] = f[j] + b*f[j-1] + f[j-2];
+        f[1] = f[1] + b;

+
+ Description: Replaced basic_op.h with the header file of the math functions
+              used in the file.
+
+ Description: Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description: Placed table declarations in a .c file, rather than an included
+ .tab.  The tables are now referenced via an extern in this file.
+
+ Description:  For Lsp_lsf()

+ FUNCTION DESCRIPTION
+
+ This function produces the number of left shifts needed to normalize the 16
+ bit variable var1 for positive values on the interval with minimum of 0x4000
+ and maximum of 0x7fff, and for negative values on the interval with minimum
+ of 0x8000 and maximum of 0xc000. Note that when var1 is zero, the resulting
+ output var_out is set to zero.

+ (3) Made numerous small changes to bring code more in line with PV standards.
+
+ Description:  For pred_ltp()
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation
+              4. Unrolled loops to speed up processing, use decrement loops,
+                 loaded into memory filter coefficient in linear order for
+                 faster execution in main loop.
+              5. Eliminated call to round by proper initialization
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations
+
+
+ Description: Changed round function name to pv_round to avoid conflict with

+ REVISION HISTORY
+
+ Description: Placed code in the PV standard template format.
+ Updated to accept new parameter, Flag *pOverflow.
+
+ Description:
+              Eliminated unused include files.
+              For Vq_subvec()
+              1. Eliminated math operations that unnecessary checked for
+                 saturation (number are bounded to 2^12)
+              2. Eliminated access to (slow) memory by using axiliar variables
+              3. Because this routine is looking for the minimum distance,
+                 introduced 3 check conditions inside the loop, so when the
+                 partial distance is bigger than the minimun distance, the
+                 loop is not completed and process continue with next iteration
+              For Vq_subvec_s()
+              1. Eliminated math operations that unnecessary checked for
+                 saturation (number are bounded to 2^12)
+              2. Combined increasing and decreasing loops to avoid double
+                 accesses to the same table element
+              3. Eliminated access to (slow) memory by using axiliar variables
+              4. Because this routine is looking for the minimum distance,
+                 introduced 2 check conditions inside the loop, so when the
+                 partial distance is bigger than the minimun distance, the
+                 loop is not completed and process continue with next iteration
+              For Q_plsf_5()
+              1. Eliminated math operations that unnecessary checked for
+                 saturation (number are bounded to 2^12)
+              2. Replaced array addressing by pointers
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+
+ Description: Added #ifdef __cplusplus around extern'ed table.

+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Quantization of 2 sets of LSF parameters using 1st order MA
+           prediction and split by 5 matrix quantization (split-MQ)
+
+ DESCRIPTION:
+
+      p[i] = pred_factor*past_rq[i];   i=0,...,m-1
+      r1[i]= lsf1[i] - p[i];           i=0,...,m-1
+      r2[i]= lsf2[i] - p[i];           i=0,...,m-1
+ where:
+      lsf1[i]           1st mean-removed LSF vector.
+      lsf2[i]           2nd mean-removed LSF vector.
+      r1[i]             1st residual prediction vector.
+      r2[i]             2nd residual prediction vector.
+      past_r2q[i]       Past quantized residual (2nd vector).
+
+ The residual vectors r1[i] and r2[i] are jointly quantized using
+ split-MQ with 5 codebooks. Each 4th dimension submatrix contains 2
+ elements from each residual vector. The 5 submatrices are as follows:
+   {r1[0], r1[1], r2[0], r2[1]};  {r1[2], r1[3], r2[2], r2[3]};
+   {r1[4], r1[5], r2[4], r2[5]};  {r1[6], r1[7], r2[6], r2[7]};
+                  {r1[8], r1[9], r2[8], r2[9]}

+ Description: Created separate file for the shr function. Sync'ed up with
+          the current template and fixed tabs.
+
+ Description: 1. Modified code by seperating var2=0 condition.
+              2. Changed Input range definitions.
+
+ Description: Made changes based on review meeting.
+              1. Changed Overflow definition.
+              2. Removed pseudo-code.
+              3. Deleted (var2>15&&var1!=0) condition.
+              4. Moved var2>0 condition in front of var2<0 condition.
+
+ Description: Changed the function prototype to pass in a pointer to the
+              overflow flag instead of using global data.
+
+ Description: Made changes per formal review. Updated template.
+              Removed code that updates MOPS counter.
+              Changed parameter name from "overflow" and "pOverflow".
+              Optimized code by eliminating unnecessary typecasting.

+    pExp = pointer to right shift to be applied to result
+    pOverflow = pointer to overflow flag
+
+ Outputs:
+    pOverflow -> if the Inv_sqrt operation resulted in an overflow.

+ FUNCTION DESCRIPTION
+
+ This function computes sqrt(L_x),  where  L_x is positive.
+ If L_var is negative or zero, the result is 0
+
+ The function sqrt(L_x) is approximated by a table and linear
+ interpolation. The square root is computed using the
+ following steps:
+    1- Normalization of L_x.
+    2- If exponent is even then shift right once.
+    3- exponent = exponent/2
+    4- i = bit25-b31 of L_x;  16<=i<=63  because of normalization.
+    5- a = bit10-b24
+    6- i -=16
+    7- L_y = table[i]<<16 - (table[i] - table[i+1]) * a * 2
+    8- return L_y and exponent so caller can do denormalization

+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description: Making changes based on comments from the review meeting.
+
+ Description: Added typedef to Input/Output Definition section.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template.
+
+ Description: Fixed typecasting issue with the TI C compiler.
+
+ Description: Modified FOR loops to count down.
+
+ Description: Modified FOR loop to count up again so that the correct values
+              are stored in the tmp buffer. Updated copyright year.
+
+ Description:
+        - Modified for loop and introduced pointers to avoid adding
+          offsets
+        - Eliminated check for saturation given that the max values of input
+          data and coefficients will not saturate the multiply and
+          accumulation
+        - eliminated memcpy to update history buffer in every pass. This is
+          done now just updating the pointers.
+
+ Description:
+              1. Eliminated unused include files.
+              2. Unrolled loops to process twice as many samples as before,
+                 this saves on memory accesses to the vector coeff. a[] and
+                 elements in the history buffer of this recursive filter
+
+ Description:
+              1. Added overflow check inside both loops. (this is needed just
+                 to satisfy bit exactness on the decoder, a faster
+                 implementation will add an extra shift, do the same,
+                 but will not be bit exact, and it may have better audio
+                 quality because will avoid clipping)
+              2. Added include file for constant definitions
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description: Using fxp_arithmetic.h that includes inline assembly functions
+              for ARM and linux-arm.
+
+ Description: Replacing fxp_arithmetic.h with basic_op.h.

+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+

+ REVISION HISTORY
+
+ Description:       AMRDecode now doesn't call getbits() or put_header_in().
+                    It also now obtains a new bit_offset value from a constant
+                    rather than from the returned value of getbits().
+
+ Description:       AMRDecode now returns byte_offset rather than bit_offset,
+                    so the program can access the next frame that is byte
+                    aligned rather than packed without padding.
+
+ Description:       The structure types Speech_Decode_FrameState are now
+                    passed into amrdecode( ) using void pointers, so that
+                    higher level functions don't need to know anything about
+                    this structure type.
+
+ Description: Changed input argument list. Added code to handle incoming DTX
+              frames, and added call to wmf_to_ets function prior to calling
+              GSMFrameDecode.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Changed all references to bit_offset to byte_offset.
+
+ Description: Added input_type to the function interface and modified code
+              to check type of conversion that needs to be made.
+
+ Description: Modified pseudo-code to include IF2 and ETS input formats.
+              Removed byte_offset from input list. Renamed speech_bits
+              to speech_bits_ptr.
+
+ Description: Added dec_input_format_tab.h in Include section. Modified
+              pseudo-code to use correct table names. Renamed input_type to
+              input_format and speech_bits to speech_bits_ptr.
+
+ Description: Removed *prev_mode_ptr in the input argument list.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Removed dec_input_format_tab.h from Include section.
+              2. Changed type definition of raw_pcm_buffer in the I/O
+                 definition section.
+
+ Description: Renamed WmfBytesPerFrame to WmfDecBytesPerFrame, and
+              If2BytesPerFrame to If2DecBytesPerFrame.
+
+ Description: Modified code so that the ETS testvectors could be fed directly
+              to this function.
+
+ Description: Changed '&' to '&&' in the setting of rx_type and mode for
+              AMR_SID < frame_type < NO_DATA case.
+
+ Description: Added code comments and made some code optimizations per Phase
+              2/3 review comments.
+
+ Description: Added conditional compile around the call to GSMFrameDecode to
+              allow amrdecode.c to be used in the ETS reference console.

+ FUNCTION DESCRIPTION
+
+ This function is the top level entry function to the GSM AMR Decoder library.
+
+ First, it checks the input format type (input_format) to determine the type
+ of de-formattting that needs to be done. If input_format is AMR_WMF, the input
+ data is in WMF (aka, non-IF2) format and the function wmf_to_ets will be
+ called to convert to the ETS format (1 bit/word, where 1 word = 16 bits),
+ and byte_offset will be updated according to the contents of WmfDecBytesPerFrame
+ table.
+
+ If input_format is AMR_IF2, the input data is in IF2 format [1] and the
+ function if2_to_ets will be called to convert to the ETS format, and
+ byte_offset will be updated according to the contents of If2DecBytesPerFrame
+ table.
+
+ The codec mode and receive frame type is initialized based on the incoming
+ frame_type.
+
+ If input_format is AMR_ETS, the input data is in the ETS format. The receive
+ frame type is set to the value in the first location of the buffer pointed to
+ by speech_bits_ptr. Then, the encoded speech parameters in the buffer pointed
+ to by speech_bits is copied to dec_ets_input_bfr and the type will be changed
+ from unsigned char to Word16. Lastly, if the receive frame type is not
+ RX_NO_DATA, the mode is obtained from the buffer pointed to by
+ speech_bits_ptr, offset by MAX_SERIAL_SIZE+1, otherwise, the mode is set to
+ the previous mode (found the in state_data->prev_mode).
+
+ If input_format is an unsupported format, byte_offset will be set to -1, to
+ indicate an error condition has occurred, and the function will exit.
+
+ If there are no errors, GSMFrameDecode is called to decode a 20 ms frame. It
+ puts the decoded linear PCM samples in the buffer pointed to by
+ raw_pcm_buffer. Then, the prev_mode field of the structure pointed to by
+ state_data is updated to the current mode.
+
+ This function returns the new byte_offset value to indicate the address
+ offset of the next speech frame to be decoded.

+ REVISION HISTORY
+
+ Description: Added BytesUsed table so that the code can allow for padding
+              at the end of each frame.
+
+ Description: Removed function prototypes for getbits, putbits,
+              put_frame_header_in, and get_frame_header_off. Removed
+              basicop_malloc.h and replaced it with typedef.h in the include
+              section. Fixed table entries for various SID modes. Removed
+              #defines because they are not used by AMRDecode function.
+              Removed tables not used by AMRDecode function.
+
+ Description: The data type Speech_Decode_FrameState is now being passed into
+              this function as a void pointer rather than a structure of type
+              Speech_Decode_FrameState.
+
+ Description: The variable decoder_state was renamed to state_data.
+
+ Description: Updated function prototype and header template.
+
+ Description: Added mode.h and frame_type_3gpp.h to include section, and
+              removed sp_dec.h.
+
+ Description: Removed definition of Changed BytesThisFrame[] table. Added
+              extern declaration for BytesThisFrame[] table.
+
+ Description: Added #define for WMF and IF2. Updated function prototype.
+
+ Description: Moved input format #defines and BytesThisFrame table to
+              dec_input_format_tab.h and dec_input_format_tab.c, respectively.
+              Updated function prototype.
+
+ Description: Updated function prototype of AMRDecode due to the removal of
+              *prev_mode_ptr. Added extern of If2BytesPerFrame
+
+ Description: Added #defines for WMF, IF2, and ETS input formats.
+
+ Description: Changed WmfBytesPerFrame to WmfDecBytesPerFrame, and
+              If2BytesPerFrame to If2DecBytesPerFrame.
+
+ Description: Renamed #defines for input format types to make it unique to the
+              decoder.
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ REVISION HISTORY
+
+ Description: Made some changes to the comments to match the comments from
+    other modules.
+
+ Description: Made changes based on comments from the review meeting.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Defined one local variable per line.
+
+ Description: Removed the functions Cb_gain_average_init and
+ Cb_gain_average_exit.  The Cb_gain_average related structure is no longer
+ dynamically allocated.
+
+ Description: Passing in pOverflow to comply with changes needed for EPOC
+              Updated the include files for the module.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions

+ REVISION HISTORY
+
+ Description: Removed the functions d_plsf_init and d_plsf_exit.
+ The d_plsf related structure is no longer dynamically allocated.
+
+ Description: Removed q_plsf_5.tab from Include section and added
+              q_plsf_5_tbl.h to Include section. Changed "mean_lsf"
+              to "mean_lsf_5" in D_plsf_reset().
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ REVISION HISTORY
+
+ Description:
+ (1) Updated to accept new parameter, Flag *pOverflow.
+ (2) Placed file in the proper PV Software template.
+
+ Description:
+ (1) Removed "count.h" and "basic_op.h" and replaced with individual include
+     files (add.h, sub.h, etc.)
+
+ Description:
+ (1) Removed optimization -- mult(i, 3, pOverflow) is NOT the same as adding
+     i to itself 3 times.  The reason is because the mult function does a
+     right shift by 15, which will obliterate smaller numbers.
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    index   -- Word16 -- received pitch index
+    t0_min  -- Word16 -- minimum of search range
+    t0_max  -- Word16 -- maximum of search range
+    i_subfr -- Word16 -- subframe flag
+    T0_prev -- Word16 -- integer pitch delay of last subframe
+                         used in 2nd and 4th subframes
+    flag4   -- Word16 -- flag for encoding with 4 bits
+
+ Outputs:
+
+    T0 -- Pointer to type Word16 -- integer part of pitch lag
+    T0_frac -- Pointer to type Word16 -- fractional part of pitch lag
+    pOverflow -- Pointer to type Flag -- Flag set when overflow occurs
+
+ Returns:
+    None.

+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Decoding of fractional pitch lag with 1/3 resolution.
+           Extract the integer and fraction parts of the pitch lag from
+           the received adaptive codebook index.
+
+  See "Enc_lag3.c" for more details about the encoding procedure.
+
+  The fractional lag in 1st and 3rd subframes is encoded with 8 bits
+  while that in 2nd and 4th subframes is relatively encoded with 4, 5
+  and 6 bits depending on the mode.

+ Functions: Dec_lag6
+
+     Date: 01/31/2002
+
+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description:
+ (1) Updated to accept new parameter, Flag *pOverflow.
+ (2) Placed file in the proper PV Software template.
+
+ Description:
+ (1) Removed "count.h" and "basic_op.h" and replaced with individual include
+     files (add.h, sub.h, etc.)
+
+ Description:
+ (1) Removed optimization -- mult(i, 3, pOverflow) is NOT the same as adding
+     i to itself 3 times.  The reason is because the mult function does a
+     right shift by 15, which will obliterate smaller numbers.
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ Description:
+
+ ------------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    index   -- Word16 -- received pitch index
+    pit_min  -- Word16 -- minimum pitch lag
+    pit_max  -- Word16 -- maximum pitch lag
+    i_subfr -- Word16 -- subframe flag
+    T0 -- Pointer to type Word16 -- integer part of pitch lag
+
+ Outputs:
+
+    T0 -- Pointer to type Word16 -- integer part of pitch lag
+    T0_frac -- Pointer to type Word16 -- fractional part of pitch lag
+    pOverflow -- Pointer to type Flag -- Flag set when overflow occurs
+
+ Returns:
+    None.
+
+ Global Variables Used:
+    None
+
+ Local Variables Needed:
+    None
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Decoding of fractional pitch lag with 1/6 resolution.
+           Extract the integer and fraction parts of the pitch lag from
+           the received adaptive codebook index.
+
+  See "Enc_lag6.c" for more details about the encoding procedure.
+
+  The fractional lag in 1st and 3rd subframes is encoded with 9 bits
+  while that in 2nd and 4th subframes is relatively encoded with 6 bits.
+  Note that in relative encoding only 61 values are used. If the
+  decoder receives 61, 62, or 63 as the relative pitch index, it means
+  that a transmission error occurred. In this case, the pitch lag from
+  previous subframe (actually from previous frame) is used.

+ REVISION HISTORY
+
+ Description: Removed the functions ec_gain_code_init, ec_gain_pitch_init,
+ ech_gain_code_exit, and ec_gain_pitch_exit.
+
+ The ec_gains related structures are no longer dynamically allocated.
+
+ Description: Updated include files and input/output sections.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Added #ifdef __cplusplus around extern'ed table.

+ Description:
+
+------------------------------------------------------------------------------
+ MODULE DESCRIPTION
+
+ These modules execute the code book gains for error concealment. This module

+ FUNCTION DESCRIPTION
+
+ This function performs a transformation on the data buffers. It converts the
+ data format from IF2 to ETS. IF2 is the storage format where the frame type
+ is in the first four bits of the first byte. The upper four bits of that byte
+ contain the first four encoded speech bits for the frame. The following bytes
+ contain the rest of the encoded speech bits. The final byte has padded zeros
+ to make the frame byte aligned. ETS format has the encoded speech
+ bits each separate with only one bit stored in each word.

+ REVISION HISTORY
+
+ Description: Removed the functions lsp_avg_init and lsp_avg_exit.
+ The lsp_avg related structure is no longer dynamically allocated.
+
+ Also, placed code in the proper PV Software Template.
+
+ Description: Per review comments, updated the inputs/outputs section
+ for the function lsp_avg.
+
+ Description: Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description: Per review comments, I added a description of pOverflow
+ to the input/output section of the template.  I also removed an unnecessary
+ include file, <stdio.h>
+
+ Description: Removed q_plsf_5.tab from Include section and added
+              q_plsf_5_tbl.h to Include section. Changed "mean_lsf"
+              to "mean_lsf_5" in lsp_avg_reset().
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ REVISION HISTORY
+
+ Description: Changed template used to PV coding template. First attempt at
+          optimizing C code.
+
+ Description: Updated file per comments gathered from Phase 2/3 review.
+
+ Description: Clarified grouping in the equation to calculated L_temp from the
+          product of state->prevCbGain and ONFACTPLUS1 in the ph_disp
+          function.
+
+ Description: Added setting of Overflow flag in inlined code.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              coding template. Removed unnecessary include files.
+
+ Description: Replaced basic_op.h with the header file of the math functions
+              used in the file.
+
+ Description: Removed the functions ph_disp_init and ph_disp_exit.
+ The ph_disp related structure is no longer dynamically allocated.
+
+ Description: Pass in pointer to overflow flag for EPOC compatibility.
+              Change code for ph_disp() function to reflect this. Remove
+              inclusion of ph_disp.tab. This table will now be referenced
+              externally.
+
+ Description: Optimized ph_disp() to reduce clock cycle usage. Updated
+              copyright year and removed unused files in Include section.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description:

+ MODULE DESCRIPTION
+
+ This file contains the function that performs adaptive phase dispersion of
+ the excitation signal. The phase dispersion initialization, reset, and
+ exit functions are included in this file, as well as, the phase dispersion

+ REVISION HISTORY
+
+ Description: Changed template used to PV coding template. First attempt at
+          optimizing C code.
+
+ Description: Updated file per comments gathered from Phase 2/3 review.
+
+ Description: Added setting of Overflow flag in inlined code.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Replaced basic_op.h with the header file of the math functions
+              used in the file.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Updated copyright year.
+              2. Modified FOR loops to count down.
+              3. Fixed typecasting issue with TI C compiler.
+              4. Added "break" statement after overflow condition occurs.
+
+ Description: Removed the functions pstfilt_init and pstfilt_exit.
+ The pst_filt related structure is no longer dynamically allocated.
+
+ Description: Modified code for EPOC changes where pOverflow is passed in
+              rather than allowing overflow to be a global variable.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations

+ REVISION HISTORY
+
+ Description: Add PV coding template. Filled out template sections and
+              reformatted code to follow C coding standard. Removed code that
+              handles SID in GSMFrameDecode.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Updated to more recent PV C coding template.
+              2. Took out all the tabs in the file and replaced with spaces.
+              3. Deleted bit_offset from input list of GSMFrameDecode.
+
+ Description: Changing several variables passed into these functions of type
+              Speech_Decode_FrameState to type void.
+
+ Description: Cleaning up brackets and line spacing for statements with
+              brackets as per a review comments.
+
+ Description: Synchronized file with UMTS version 3.2.0. Removed unnecessary
+              include files.
+
+ Description: Removed all references to malloc/free, except for the top-level
+ malloc in GSMInitDecode, and corresponding free in GSMDecodeFrameExit.
+
+ Also, modified function calls throughout to reflect the fact that the members
+ of the structure Decoder_amrState are no longer pointers to be set via
+ malloc, but full-blown structures.  (Changes of the type D_plsfState *lsfState
+ to D_plsfState lsfState)
+
+ Description: Created overflow and pass the variable into the decoder.
+
+ Description: Changed inititlaization of the pointer to overflow flag. Removed
+              code related to MOPS counter.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations

+ FUNCTION DESCRIPTION
+
+ This function is the entry point to the GSM AMR decoder. The following
+ operations are performed on one received frame: First, the codec
+ parameters are parsed from the buffer pointed to by serial according to
+ frame_type. Then the AMR decoder is invoked via a call to Decoder_amr. Post
+ filtering of the decoded data is done via a call to Post_Filter function.
+ Lastly, the decoded data is post-processed via a call to Post_Process
+ function. If NO13BIT is not defined, the contents of the buffer pointed to
+ by synth is truncated to 13 bits. It remains unchanged otherwise.

+ FUNCTION DESCRIPTION
+
+ This function performs a transformation on the data buffers. It converts the
+ data format from WMF (non-IF2) (Wireless Multi-media Forum) to ETS (European
+ Telecommunication Standard). WMF format has the encoded speech bits byte
+ aligned with MSB to LSB going left to right. ETS format has the encoded speech
+ bits each separate with only one bit stored in each word.

+## Media Testing ##
+---
+#### AMR-NB Decoder :
+The Amr-Nb Decoder Test Suite validates the amrnb decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrnbDecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/AmrnbDecoderTest/AmrnbDecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrnbDecoderTest/AmrnbDecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/amrnb/dec/test/AmrnbDecoderTest.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push AmrnbDecoderTestRes/. /data/local/tmp/
+```
+
+usage: AmrnbDecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrnbDecoderTest -P /data/local/tmp/AmrnbDecoderTestRes/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest AmrnbDecoderTest -- --enable-module-dynamic-download=true
+```

+# Fuzzer for libstagefright_amrnbenc encoder
+
+## Plugin Design Considerations
+The fuzzer plugin for AMR-NB is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+AMR-WB supports the following parameters:
+1. Output Format (parameter name: `outputFormat`)
+2. Mode (parameter name: `mode`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `outputFormat` | 0. `AMR_TX_WMF` 1. `AMR_TX_IF2` 2. `AMR_TX_ETS` | Bits 0, 1 and 2 of 1st byte of data. |
+| `mode`   | 0. `MR475` 1. `MR515` 2. `MR59` 3. `MR67`  4. `MR74 ` 5. `MR795` 6. `MR102` 7. `MR122` 8. `MRDTX` | Bits 3, 4, 5 and 6 of 1st byte of data. |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec using a loop.
+If the encode operation was successful, the input is advanced by the frame size.
+If the encode operation was un-successful, the input is still advanced by frame size so
+that the fuzzer can proceed to feed the next frame.
+
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build amrnb_enc_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) amrnb_enc_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some pcm files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/amrnb_enc_fuzzer/amrnb_enc_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/amrnb_enc_fuzzer/amrnb_enc_fuzzer CORPUS_DIR
+```

+ FUNCTION DESCRIPTION
+
+ This function is the top-level entry point to the GSM AMR Encoder library.
+
+ The following describes the encoding process for WMF or IF2 formatted output
+ data. This functions calls GSMEncodeFrame to encode one frame's worth of
+ input speech samples, and returns the newly encoded bit stream in the buffer
+ pointed to by pEncOutput.Then the function sid_sync is called to determine
+ the transmit frame type. If the transmit frame type is TX_SPEECH_GOOD or
+ TX_SID_FIRST or TX_SID_UPDATE, p3gpp_frame_type will be set to the encoder
+ used mode. For SID frames, the SID type information and mode information are
+ added to the encoded parameter bitstream according to the SID frame format
+ described in [1]. If the transmit frame type is TX_NO_DATA, the store
+ pointed to by p3gpp_frame_type will be set to NO_DATA. Then the output
+ format type (output_format) will be checked to determine the format of the
+ encoded data.
+
+ If output_format is AMR_TX_WMF, the function ets_to_wmf will be called to
+ convert from ETS format (1 bit/word, where 1 word = 16 bits, information in
+ least significant bit) to WMF (aka, non-IF2). The WMF format stores the data
+ in octets. The least significant 4 bits of the first octet contains the 3GPP
+ frame type information and the most significant 4 bits are zeroed out. The
+ succeeding octets contain the packed encoded speech bits. The total number of
+ WMF bytes encoded is obtained from WmfEncBytesPerFrame table and returned via
+ num_enc_bytes.
+
+ If output_format is AMR_TX_IF2, the function if2_to_ets will be called to
+ convert from ETS format to IF2 [1]. The IF2 format stores the data in octets.
+ The least significant nibble of the first octet contains the 3GPP frame type
+ and the most significant nibble contains the first 4 encoded speech bits. The
+ suceeding octets contain the packed encoded speech bits. The total number of
+ IF2 bytes encoded is obtained from If2EncBytesPerFrame table and returned via
+ num_enc_bytes.
+
+ If output_format is AMR_TX_ETS, GSMFrameEncode is called to generate the
+ encoded speech parameters, then, sid_sync is called to determine the transmit
+ frame type. If the transmit frame type is not TX_NO_DATA, then the transmit
+ frame type information is saved in the first location of the ets_output_bfr,
+ followed by the encoded speech parameters. The codec mode information is
+ stored immediately after the MAX_SERIAL_SIZE encoded speech parameters. If
+ the transmit frame type is TX_NO_DATA, the transmit frame type, encoded
+ speech parameters, and codec mode are stored in the same order as before
+ in ets_output_bfr. However, for the no data case, the codec mode is set to
+ -1.
+
+ After all the required information is generated, the 16-bit data generated
+ by the Encoder (in ets_output_bfr) is copied to the buffer pointed to by
+ pEncOutput in the little endian configuration, i.e., least significant byte,
+ followed by most significant byte. The num_enc_bytes is set to
+ 2*(MAX_SERIAL_SIZE+2).
+
+ If output_format is invalid, this function flags the error and sets
+ num_enc_bytes to -1.

+ REVISION HISTORY
+
+ Description: Put into template...starting optimization.
+
+ Description: Removed call to mult_r routine.
+
+ Description: Modified Input/Output Definitions section to comply with the
+          current template. Fixed tabs.
+
+ Description: Updated Input/Output definitions by making them more
+          descriptive.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Added full pathname of file.
+              2. Fixed typecasting issue with TI compiler.
+              3. Modified FOR loops to count down.
+              4. Added comment to the code.
+
+ Description: Removed extern to global paramter (Flag Overflow) and replaced
+ by passing in a pointer to Overflow.  Also, made several small changes to
+ bring code more in line with PV Standards.
+
+ Description:
+            1. Added pointer to avoid adding offsets in every pass
+            2. Break last loop in two nested loop to speed up processing
+            3. Removed extra check for overflow by doing scaling right
+               after overflow is detected.
+            4. Eliminated calls to basic operations (like extract) not
+               needed because of the nature of the number (all bounded)
+
+ Description:
+              1. Fixed for:
+                overflow check was looking for positive number before a left
+                shift. When numbers were big enough, positive numbers after
+                shifted became negative, causing a 1/0 division).
+                Fixed so now it checks for numbers lesser than 0x40000000
+                before the left shift
+
+ Description:
+              1.Modified check for saturation to match bit exact test.
+                Also, when saturation is reached, a faster loop is used
+                (with no energy accumulation) to speed up processing
+
+
+ Description:
+              1.Added pointer initialization to for loop when saturation
+                is found. This because some compiler ( like Vcpp in release
+                mode) when optimizing code, may remove pointer information
+                once the loop is broken.
+
+ Description:  Added casting to eliminate warnings
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Using inlines from fxp_arithmetic.h.

+----------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    x = buffer of input signals of type Word16
+    m = LPC order of type Word16
+    wind = buffer of window signals of type Word16
+    r_h = buffer containing the high word of the autocorrelation values
+          of type Word16
+    r_l = buffer containing the low word of the autocorrelation values
+          of type Word16
+
+    pOverflow = pointer to variable of type Flag *, which indicates if
+                overflow occurs.
+
+ Outputs:
+    r_h buffer contains the high word of the new autocorrelation values
+    r_l buffer contains the low word of the new autocorrelation values
+    pOverflow -> 1 if overflow occurs.

+ FUNCTION DESCRIPTION
+
+ This function searches a 35 bit algebraic codebook containing 10 pulses in a
+ frame of 40 samples.
+
+ The code contains 10 nonzero pulses: i0...i9.
+ All pulses can have two possible amplitudes: +1 or -1.
+ The 40 positions in a subframe are divided into 5 tracks of
+ interleaved positions. Each track contains two pulses.
+ The pulses can have the following possible positions:
+
+    i0, i5 :  0, 5, 10, 15, 20, 25, 30, 35.
+    i1, i6 :  1, 6, 11, 16, 21, 26, 31, 36.
+    i2, i7 :  2, 7, 12, 17, 22, 27, 32, 37.
+    i3, i8 :  3, 8, 13, 18, 23, 28, 33, 38.
+    i4, i9 :  4, 9, 14, 19, 24, 29, 34, 39.
+
+ Each pair of pulses require 1 bit for their signs and 6 bits for their
+ positions (3 bits + 3 bits). This results in a 35 bit codebook.
+ The function determines the optimal pulse signs and positions, builds
+ the codevector, and computes the filtered codevector.

+     FUNCTION DESCRIPTION
+
+     This function searches a 9 bit algebraic codebook containing 2 pulses in a
+     frame of 40 samples.
+
+     The code length is 40, containing 2 nonzero pulses: i0...i1. All pulses can
+     have two possible amplitudes: +1 or -1. Pulse i0 can have 8 possible positions,
+     pulse i1 can have 8 positions. Also coded is which track pair should be used,
+     i.e. first or second pair. Where each pair contains 2 tracks.
+
+        First subframe:
+        first   i0 :  0, 5, 10, 15, 20, 25, 30, 35.

+ The flag is passed back to the calling function by pointer reference.
+
+ Description: Optimized file to reduce clock cycle usage. Updated copyright
+              year. Removed unneccesary include files and added only the
+              include files for the math functions used. Removed unused
+              #defines.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ FUNCTION DESCRIPTION
+
+ FUNCTION:
+
+ PURPOSE:  Searches a 31 bit algebraic codebook containing 8 pulses
+           in a frame of 40 samples.
+
+ DESCRIPTION:
+   The code contains 8 nonzero pulses: i0...i7.
+   All pulses can have two possible amplitudes: +1 or -1.
+   The 40 positions in a subframe are divided into 4 tracks of
+   interleaved positions. Each track contains two pulses.
+   The pulses can have the following possible positions:
+
+      i0, i4 :  0, 4, 8,  12, 16, 20, 24, 28, 32, 36
+      i1, i5 :  1, 5, 9,  13, 17, 21, 25, 29, 33, 37
+      i2, i6 :  2, 6, 10, 14, 18, 22, 26, 30, 34, 38
+      i3, i7 :  3, 7, 11, 15, 19, 23, 27, 31, 35, 39
+
+   Each pair of pulses require 1 bit for their signs. The positions
+   are encoded together 3,3 and 2 resulting in
+   (7+3) + (7+3) + (5+2) bits for their
+   positions. This results in a 31 (4 sign and 27 pos) bit codebook.
+   The function determines the optimal pulse signs and positions, builds
+   the codevector, and computes the filtered codevector.

+ REVISION HISTORY
+
+ Description: Made changes based on comments from the review meeting.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Added initialization of the overflow flag in cod_amr_init()
+              and in cod_amr_reset(). This overflow flag is now part of
+              the cod_amrState structure.
+
+ Description: Cleaned up INCLUDES. removed inclusion of basic_op.h and repeat
+              inclusion of copy.h
+
+ Description: Updated function call to dtx_enc
+
+ Description:  For cod_amr_first() and cod_amr()
+              1. Replaced copy() function with memcpy()
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ FUNCTION DESCRIPTION
+
+ This function is the main encoder routine. It is called every 20 ms speech
+ frame, operating on the newly read 160 speech samples. It performs the
+ principle encoding functions to produce the set of encoded parameters
+ which include the LSP, adaptive codebook, and fixed codebook
+ quantization indices (addresses and gains).
+
+ Before calling this function, 160 new speech data should be copied to the
+ vector new_speech[]. This is a global pointer which is declared in
+ this file (it points to the end of speech buffer minus 160).
+
+ The outputs of the function are:
+     ana[]:     vector of analysis parameters.
+     synth[]:   Local synthesis speech (for debugging purposes)

+ REVISION HISTORY
+
+ Description: Optimize for speed. Update to code template.
+
+ Description: Added author name and date, fixed tabs, and added missing
+          sections. Updated Input/Output section.
+
+ Description: Optimized code by calculating two convolution sums per iteration
+          of the outer loop, thereby, decreasing outer loop count by 2.
+          Updated input/output definitions to be the same as the assembly
+          file (convolve.asm). Left Pseudo-code section blank.
+

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template. First attempt at
+          optimizing C code.
+
+ Description: Used MAX_16 and MIN_16 when checking the result of Inv_sqrt.
+          Synced up to the new template.
+
+ Description: Added setting of Overflow flag in inlined code.
+
+ Description: Took out cor_h_x function and put it in its own file. Sync'ed
+          up with the single_func_template.c template. Delete version
+          ID variable.
+
+ Description: Synchronized file with UTMS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Fixed portion of the code that builds the rr[] matrix. There
+              was an error in the original inlining of code that caused
+              the code to be not bit-exact with UMTS version 3.2.0.
+
+ Description: Added calls to L_add() and mult() in the code to handle overflow
+              scenario. Moved cor_h.h after cnst.h in the Include section.
+              Doing this allows the unit test to build using the cnst.h in the
+              /test/include directory. Fixed initialization of the accumulator
+              in the first calculation of the sum of squares.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Used #define value instead of hard-coded numbers in the code.
+              2. Fixed typecasting issue with TI C compiler.
+              3. Removed typecasting of 0x00008000L in the call to L_add.
+
+ Description: Changed pOverflow from a global variable into a function
+ parameter.
+
+ Description:
+            1. Added pointer to avoid adding offsets in every pass
+            2. Eliminate variables defined as registers
+            3. Removed extra check for overflow by doing scaling right
+               after overflow is detected.
+            4. Eliminated calls to basic operations (like extract) not
+               needed because of the nature of the number (all bounded)
+            5. Eliminated duplicate loop accessing same data
+            6. Simplified matrix addressing by use of pointers
+
+ Description:
+              1. Eliminated unused include files.
+              2. Access twice the number of points when delaing with matrices
+                 and in the process only 3 pointers (instead of 4) are needed
+              3. Replaced array addressing (array sign[]) by pointers
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description: Using inlines from fxp_arithmetic.h .
+
+ Description: Replacing fxp_arithmetic.h with basic_op.h.

+ REVISION HISTORY
+
+ Description: Created a separate file for cor_h_x function.
+
+ Description: Synchronized file with UMTS versin 3.2.0. Updated coding
+              template.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Modified FOR loop in the code to count down.
+              2. Fixed typecasting issue with TI C compiler.
+
+ Description: Added call to round() and L_shl() functions in the last FOR
+              loop to make code bit-exact. Updated copyright year.
+
+ Description: Modified to pass pOverflow in via a pointer, rather than
+ invoking it as a global variable.
+
+ Description: Made the following changes
+              1. Unrolled the correlation loop and add mechanism control
+                 to compute odd or even number of computations.
+              2. Use pointer to avoid continuos addresses calculation
+              2. Eliminated math operations that check for saturation.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ FUNCTION DESCRIPTION
+
+ This function computes the correlation between the target signal (x) and the
+ impulse response (h).
+
+ The correlation is given by: d[n] = sum_{i=n}^{L-1} x[i] h[i-n],
+ where: n=0,...,L-1
+
+ d[n] is normalized such that the sum of 5 maxima of d[n] corresponding to
+ each position track does not saturate.

+         length is L_CODE
+    sf = scaling factor of type Word16 ; 2 when mode is MR122, 1 for all
+         other modes
+    nb_track = number of ACB tracks (Word16)
+    step = step size between pulses in one track (Word16)
+    pOverflow = pointer to overflow (Flag)
+
+ Outputs:
+    dn contents are the newly calculated correlation values
+    pOverflow = 1 if the math functions called by cor_h_x2 result in overflow
+    else zero.
+
+ Returns:
+    None
+
+ Global Variables Used:
+    None
+
+ Local Variables Needed:

+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function computes the correlation between the target signal (x) and the
+ impulse response (h).
+
+ The correlation is given by: d[n] = sum_{i=n}^{L-1} x[i] h[i-n],
+ where: n=0,...,L-1
+
+ d[n] is normalized such that the sum of 5 maxima of d[n] corresponding to
+ each position track does not saturate.

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template. First attempt at
+          optimizing C code.
+
+ Description: Updated file per comments gathered from Phase 2/3 review.
+          Synched up with new template (Inputs/Outputs section). Deleted
+          lines leftover from original code prior to the code section of
+          dtx_enc_exit function. Deleted confusing comment in the log_en
+          calculation in dtx_enc function. Restructured IF statement in
+          the calculation of the sum of squares of speech signals in
+          dtx_buffer.
+
+ Description: Added setting of Overflow flag in inlined code.
+
+ Description: Synchronized file with UTMS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Modified FOR loops to count down.
+              2. Fixed typecasting issue with TI C compiler.
+              3. Fixed comment in dtx_enc pseudo-code.
+              4. Added dtx_enc code comment pertaining to possible assembly
+                 implementation.
+
+ Description: Added calls to add() in tx_dtx_handler. Updated copyright year.
+
+ Description: Pass in pointer to overflow flag to all functions requiring this
+              flag. This is to make the library EPOC compatible.
+
+ Description:  For dtx_enc_reset() only
+              1. Replaced copy() with memcpy.
+              2. Eliminated include file copy.h
+              3. Eliminated printf statement
+              For dtx_buffer()
+              1. Replaced copy() with memcpy.
+              2. Eliminated math operations that unnecessary checked for
+                 saturation, in some cases this by shifting before adding and
+                 in other cases by evaluating the operands
+              3. Unrolled loop to speed up execution
+
+ Description:  For dtx_buffer()
+              1. Modified scaling and added check for saturation. Previous
+                 scaling was correct but altered precision, this cause bit
+                 exactness test failure.
+
+ Description:  For dtx_buffer()
+              1. Modified scaling and saturation checks. Previous
+                 scaling was correct but altered precision, this cause bit
+                 exactness test failure for dtx vad2.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ FUNCTION DESCRIPTION
+
+ This function implements the encoding of fractional pitch lag with
+ 1/3 resolution.
+
+ *   FUNCTION:  Enc_lag3
+ *
+ *   PURPOSE:  Encoding of fractional pitch lag with 1/3 resolution.
+ *
+ *   DESCRIPTION:
+ *                    First and third subframes:
+ *                    --------------------------
+ *   The pitch range is divided as follows:
+ *           19 1/3  to   84 2/3   resolution 1/3
+ *           85      to   143      resolution 1
+ *
+ *   The period is encoded with 8 bits.
+ *   For the range with fractions:
+ *     index = (T-19)*3 + frac - 1;
+ *                         where T=[19..85] and frac=[-1,0,1]
+ *   and for the integer only range
+ *     index = (T - 85) + 197;        where T=[86..143]
+ *
+ *                    Second and fourth subframes:
+ *                    ----------------------------
+ *   For the 2nd and 4th subframes a resolution of 1/3 is always used,
+ *   and the search range is relative to the lag in previous subframe.
+ *   If t0 is the lag in the previous subframe then
+ *   t_min=t0-5   and  t_max=t0+4   and  the range is given by
+ *        t_min - 2/3   to  t_max + 2/3
+ *
+ *   The period in the 2nd (and 4th) subframe is encoded with 5 bits:
+ *     index = (T-(t_min-1))*3 + frac - 1;
+ *                 where T=[t_min-1..t_max+1]

+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Encoding of fractional pitch lag with 1/6 resolution.
+
+ DESCRIPTION:
+                  First and third subframes:
+                  --------------------------
+ The pitch range is divided as follows:
+         17 3/6  to   94 3/6   resolution 1/6
+         95      to   143      resolution 1
+
+ The period is encoded with 9 bits.
+ For the range with fractions:
+   index = (T-17)*6 + frac - 3;
+                       where T=[17..94] and frac=[-2,-1,0,1,2,3]
+ and for the integer only range
+   index = (T - 95) + 463;        where T=[95..143]
+
+                  Second and fourth subframes:
+                  ----------------------------
+ For the 2nd and 4th subframes a resolution of 1/6 is always used,
+ and the search range is relative to the lag in previous subframe.
+ If t0 is the lag in the previous subframe then
+ t_min=t0-5   and  t_max=t0+4   and  the range is given by
+     (t_min-1) 3/6   to  (t_max) 3/6
+
+ The period in the 2nd (and 4th) subframe is encoded with 6 bits:
+   index = (T-(t_min-1))*6 + frac - 3;
+               where T=[t_min-1..t_max] and frac=[-2,-1,0,1,2,3]
+
+ Note that only 61 values are used. If the decoder receives 61, 62,
+ or 63 as the relative pitch index, it means that a transmission
+ error occurred and the pitch from previous subframe should be used.

+ FUNCTION DESCRIPTION
+
+ This function performs a transformation on the data buffers. It converts the
+ data format from ETS (European Telecommunication Standard) to IF2. ETS format
+ has the encoded speech bits each separate with only one bit stored in each
+ word. IF2 is the storage format where the frame type is in the first four bits
+ of the first byte. The upper four bits of that byte contain the first four
+ encoded speech bits for the frame. The following bytes contain the rest of
+ the encoded speech bits. The final byte has padded zeros  to make the frame
+ byte aligned.

+ FUNCTION DESCRIPTION
+
+ This function performs a transformation on the data buffers. It converts the
+ data format from ETS (European Telecommunication Standard) to WMF (wireless
+ multimedia forum). ETS format has the encoded speech bits each separate with
+ only one bit stored in each word. WMF is the storage format where the frame
+ type is in the first four bits of the first byte. This first byte has the
+ upper four bits as padded zeroes. The following bytes contain the rest of the
+ encoded speech bits. The final byte has padded zeros to make the frame byte
+ aligned.

+ FUNCTION DESCRIPTION
+
+ This function computes the pitch (adaptive codebook) gain. The adaptive
+ codebook gain is given by
+
+    g = <x[], y[]> / <y[], y[]>
+
+    where:  x[] is the target vector
+            y[] is the filtered adaptive codevector
+            <> denotes dot product.
+
+ The gain is limited to the range [0,1.2] (=0..19661 Q14)
+

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template.
+ Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description: Removed everything associated with gc_pred_init
+ and gc_pred_exit.  gc_pred_exit was simply removed -- gc_pred_init
+ was replaced with calls to gc_pred_reset.  This is because the gc_pred
+ related structures are no longer dynamically allocated via malloc.
+
+ Description:  For gainQuant()
+              1. Replaced gc_pred_copy() with memcpy.
+              2. Eliminated unused include file gc_pred.h.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ REVISION HISTORY
+
+ Description: Placed header file in the proper template format.  Added
+ parameter pOverflow.
+
+ Description: Changed definition of...
+
+    gc_predState     gc_predSt;
+    gc_predState     gc_predUnqSt;
+
+  in the structure typedef.  These are no longer pointers, which avoids
+  the need to malloc memory for the pointers.  They are, rather, the actual
+  structure declared within the gainQuantState structure.
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Moved _cplusplus #ifdef after Include section.
+

+ REVISION HISTORY
+
+ Description: Changing code as per review comments. These changes include
+              removing unnecessary tables and changing function descriptions.
+              The comments were changed to "slash-star" rather than double
+              slash, and some wordings of comments were corrected.
+
+ Description: Replaced GSMEncodeFrame function prototype with that of
+              AMREncode. Updated copyright year.
+
+ Description: Added #define for WMF and IF2, and updated function prototype
+              of AMREncode.
+
+ Description: Renamed WMF and IF2 to AMR_WMF and AMR_IF2, respectively. Added
+              AMR_ETS, and changed output_type to output_format in the
+              function prototype of AMREncode(). Removed function prototypes
+              for frame_header_move() and reverse_bits() since they are not
+              needed anymore.
+
+ Description: Moved WMFBytesUsed and IF2BytesUsed tables to
+              enc_output_format_tab.c.
+
+ Description: Added function prototypes for init, reset, and exit functions
+              in amrencode.c. Renamed output format #defines so that it it
+              unique to the encoder.
+
+ Description: Added comment to describe L_FRAME.
+
+ Description: Added Frame_Type_3GPP type definition.
+
+ Description: Moved _cplusplus #ifdef after Include section.

+ REVISION HISTORY
+
+ Description:
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation
+              4. Unrolled loops to speed up processing, use decrement loops
+              5. Eliminated call to round by proper initialization
+
+ Description:  Added casting to eliminate warnings
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description: Using intrinsics from fxp_arithmetic.h .
+

+    A[1] = K
+    Alpha = R[0] * (1-K**2]

+        ENDFOR
+
+        An[i]=K
+        Alpha=Alpha * (1-K**2)
+
+    END
+
+ where:

+    A[i] = filter coefficients
+    K = reflection coefficient

+
+ Description: t0 was not being declared as Word32.
+
+ Description:  Replaced OSCL mem type functions and eliminated include

+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ REVISION HISTORY
+
+ Description: Added pOverflow as a passed in value to searchFrac and made
+              other fixes to the code regarding simple syntax fixes. Removed
+              the include of stio.h.
+
+ Description: *lag-- decrements the pointer.  (*lag)-- decrements what is
+ pointed to.  The latter is what the coder intended, but the former is
+ the coding instruction that was used.
+
+ Description: A common problem -- a comparison != 0 was inadvertantly replaced
+ by a comparison == 0.
+
+
+ Description:  For Norm_Corr() and getRange()
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation, in some cases this by shifting before adding and
+                 in other cases by evaluating the operands
+              4. Unrolled loops to speed up processing, use decrement loops
+              5. Replaced extract_l() call with equivalent code
+              6. Modified scaling threshold and group all shifts (avoiding
+                 successive shifts)
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Removed compiler warnings.

+  FUNCTION:   Norm_Corr()
+
+  PURPOSE: Find the normalized correlation between the target vector
+           and the filtered past excitation.
+
+  DESCRIPTION:
+     The normalized correlation is given by the correlation between the
+     target and filtered past excitation divided by the square root of
+     the energy of filtered excitation.
+                   corr[k] = <x[], y_k[]>/sqrt(y_k[],y_k[])
+     where x[] is the target vector and y_k[] is the filtered past
+     excitation at delay k.

+ FUNCTION DESCRIPTION
+
+ Find the lag that has maximum correlation of scal_sig in a given delay range.
+ The correlation is given by:
+
+         cor[t] = <scal_sig[n],scal_sig[n-t]>,  t=lag_min,...,lag_max
+
+ The function returns the maximum correlation after normalization and the
+ corresponding lag.

+ FUNCTION DESCRIPTION
+
+ This function computes the open loop pitch lag based on the perceptually
+ weighted speech signal. This is done in the following steps:
+       - find three maxima of the correlation <sw[n],sw[n-T]>,
+         dividing the search range into three parts:
+              pit_min ... 2*pit_min-1
+            2*pit_min ... 4*pit_min-1
+            4*pit_min ...   pit_max
+       - divide each maximum by <sw[n-t], sw[n-t]> where t is the delay at
+         that maximum correlation.
+       - select the delay of maximum normalized correlation (among the
+         three candidates) while favoring the lower delay ranges.

+ REVISION HISTORY
+
+ Description: Put the file into our template structure.
+
+ Description: First pass optimization.
+
+ Description: Made changes based on comments from review meeting.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Removed basic_op.h from the Include section. It is not used.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Fixed typecasting issue with TI C compiler.
+              2. Modified FOR loop to count down.
+              3. Cosmetic changes to the code to make address post-increment
+                 clearer.
+              4. Removed unnecessary typecasting in the multiply-accumulate
+                 portion of FOR loop body.
+              5. Removed "static" in table definitions.
+              6. Updated copyright year.
+
+ Description:  For Pre_Process()
+              1. Replaced variables (containing filter coefficients) with
+                 constants, to avoid extra register swaping.
+              2. Changed to decrement loop
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template.
+ Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description:
+ (1) Removed optimization -- mult(i, 3, pOverflow) is NOT the same as adding
+     i to itself 3 times.  The reason is because the mult function does a
+     right shift by 15, which will obliterate smaller numbers.
+
+ Description:
+              1. Eliminated unused include files.
+              2. Eliminated math operations that unnecessary checked for
+                 saturation by evaluating the operands
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template.
+ Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description:
+ (1) Removed optimization -- mult(i, 3, pOverflow) is NOT the same as adding
+     i to itself 3 times.  The reason is because the mult function does a
+     right shift by 15, which will obliterate smaller numbers.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description: Added #ifdef __cplusplus around extern'ed table.

+ REVISION HISTORY
+
+ Description: Adding pOverflow to the functions to remove global variables.
+              These changes are needed for the EPOC releases. Cleaned up code.
+              Updated template.
+
+ Description: Changed temp to temp32. When temp was only 16 bits it was not
+              holding the 32 bit value returned from the functions. Some
+              variables were also being declared as Word16 rather than Word32
+              as they were suposed to be.
+
+ Description: Changed copyright year. Removed all calls to math functions by
+              inlining them, and removed all unnecessary files in the Include
+              section.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Removed all #defines.
+              2. Used a pointer to &codvec[0] instead of array indexing.
+              3. Removed multiple data casting in the code.
+
+ Description:
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers, this by taking
+                 advantage of the fact that the autocrrelation  matrix is
+                 a toeplitz matrix, so r[i][j] = r[j][i], then a single
+                 pointer can be used to address a matrix. The use of this
+                 is not uniform along the function (due to compiler limitations:
+                 handling so many variables in this file) so the use
+                 of this is pointer optimizations is limited to places
+                 where the ARM compiler provides the lesses numer of cycles
+              3. Eliminated use of intermediate variables to accelerate
+                 comparisons (like in the nested loops)
+              4. Introduced array temp1[], to pre-calculate the elements
+                 used in the nested loops, in this way the calculation is
+                 not repeated in every loop iteration. This is done for
+                 loops i3-i5-i7 and i9
+              5. Use array Index[] to store indexes i1:i9, and then use memcpy
+                 to update indexes.
+              6. Eliminated shifts by modifying the way number are rounded,
+                 this does not have any effect in ARM processors but may help
+                 other compilers
+
+ Description:
+              1. When storing indexes, added memcpy() to support the rates
+                 that use this function: 12.2 (already done) and 10.2 (missing).
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ REVISION HISTORY
+
+ Description:  Placed into PV template and optimized.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Replaced basic_op.h with the header files of the math functions
+              used in the file.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Modified certain FOR loops to count down.
+              2. Modified code for further optimization.
+
+ Description: Modified FOR loops in set_sign12k2 to count up. The FOR loops
+              affected are the loop that calculates the starting position of
+              each incoming pulse, and the loop that calculates the position
+              of the max correlation. Updated copyright year.
+
+ Description: Passing in pointer to overflow flag for EPOC compatibility.
+
+ Description:  For set_sign12k2()
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation, this by evaluating the operands
+              4. Replaced loop counter with decrement loops
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ FUNCTION DESCRIPTION
+
+ This function is the entry point to the GSM AMR encoder. The following
+ operations are performed to generate one encoded frame: First, the incoming
+ audio samples are passed through the pre-processing filter where they are
+ filtered and downscaled. A call is then made to the main encoder cod_amr().
+ This generates the set of encoded parameters which include the LSP, adaptive
+ codebook, and fixed codebook quantization indices (addresses and gains). The
+ generated parameters are then converted to serial bits.

+## Media Testing ##
+---
+#### AMR-NB Encoder :
+The Amr-Nb Encoder Test Suite validates the amrnb encoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrnbEncoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/AmrnbEncoderTest/AmrnbEncoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrnbEncoderTest/AmrnbEncoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/amrnb/enc/test/AmrnbEncoderTest.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push AmrnbEncoderTestRes/. /data/local/tmp/
+```
+
+usage: AmrnbEncoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrnbEncoderTest -P /data/local/tmp/AmrnbEncoderTestRes/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest AmrnbEncoderTest -- --enable-module-dynamic-download=true
+```

+# Fuzzer for libstagefright_amrnbdec decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for AMR-NB is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+AMR-NB supports the following parameters:
+1. Stream format (parameter name: `input_format`)
+2. 3GPP frame type (parameter name: `frame_type`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `input_format` | 0. `MIME_IETF` 1. `IF2` | Bit 0 (LSB) of 1st byte of data. |
+| `frame_type`   | 0. `AMR_475` 1. `AMR_515` 2. `AMR_59` 3. `AMR_67`  4. `AMR_74` 5. `AMR_795` 6. `AMR_102` 7. `AMR_122`  | Bits 3, 4 and 5 of 1st byte of data. |
+
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec using a loop.
+If the decode operation was successful, the input is advanced by the frame size
+which is based on `input_format` and `frame_type` selected.
+If the decode operation was un-successful, the input is still advanced by frame size so
+that the fuzzer can proceed to feed the next frame.
+
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build amrnb_dec_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) amrnb_dec_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some amrnb files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/amrnb_dec_fuzzer/amrnb_dec_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/amrnb_dec_fuzzer/amrnb_dec_fuzzer CORPUS_DIR
+```

+# Fuzzer for libstagefright_amrwbdec decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for AMR-WB is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+AMR-WB supports the following parameters:
+1. Quality (parameter name: `quality`)
+2. Mode (parameter name: `mode`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `quality` | 0. `Bad Quality` 1. `Good quality` | Bit 0 (LSB) of 1st byte of data. |
+| `mode`   | 0. `MODE_7k` 1. `MODE_9k` 2. `MODE_12k` 3. `MODE_14k`  4. `MODE_16k ` 5. `MODE_18k` 6. `MODE_20k` 7. `MODE_23k` 8. `MODE_24k` 9. `MRDTX`  | Bits 3, 4, 5 and 6 of 1st byte of data. |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec using a loop.
+If the decode operation was successful, the input is advanced by the frame size
+which is based on `mode` and `quality` selected.
+If the decode operation was un-successful, the input is still advanced by frame size so
+that the fuzzer can proceed to feed the next frame.
+
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build amrwb_dec_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) amrwb_dec_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some amrwb files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/amrwb_dec_fuzzer/amrwb_dec_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/amrwb_dec_fuzzer/amrwb_dec_fuzzer CORPUS_DIR
+```

+#### AMR-WB Decoder :
+The Amr-Wb Decoder Test Suite validates the amrwb decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrwbDecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/AmrwbDecoderTest/AmrwbDecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrwbDecoderTest/AmrwbDecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/amrwb/test/AmrwbDecoderTest.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push AmrwbDecoderTestRes/. /data/local/tmp/
+```
+
+usage: AmrwbDecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrwbDecoderTest -P /data/local/tmp/AmrwbDecoderTestRes/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest AmrwbDecoderTest -- --enable-module-dynamic-download=true
+```

+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# Fuzzer for libstagefright_amrwbenc encoder
+
+## Plugin Design Considerations
+The fuzzer plugin for AMR-WB is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+AMR-WB supports the following parameters:
+1. Frame Type (parameter name: `frameType`)
+2. Mode (parameter name: `mode`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `frameType` | 0. `VOAMRWB_DEFAULT` 1. `VOAMRWB_ITU` 2. `VOAMRWB_RFC3267` | Bits 0, 1 and 2 of 1st byte of data. |
+| `mode`   | 0. `VOAMRWB_MD66` 1. `VOAMRWB_MD885` 2. `VOAMRWB_MD1265` 3. `VOAMRWB_MD1425`  4. `VOAMRWB_MD1585 ` 5. `VOAMRWB_MD1825` 6. `VOAMRWB_MD1985` 7. `VOAMRWB_MD2305` 8. `VOAMRWB_MD2385` 9. `VOAMRWB_N_MODES` | Bits 4, 5, 6 and 7 of 1st byte of data. |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec using a loop.
+If the encode operation was successful, the input is advanced by the frame size.
+If the encode operation was un-successful, the input is still advanced by frame size so
+that the fuzzer can proceed to feed the next frame.
+
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build amrwb_enc_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) amrwb_enc_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some pcm files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/amrwb_enc_fuzzer/amrwb_enc_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/amrwb_enc_fuzzer/amrwb_enc_fuzzer CORPUS_DIR
+```

+ * Remarks on the dynamics of the calculations.                              *
+ *                                                                           *
+ *       The numbers used are in double precision in the following format :  *
+ *       A = AH <<16 + AL<<1.  AH and AL are 16 bit signed integers.         *
+ *       Since the LSB's also contain a sign bit, this format does not       *
+ *       correspond to standard 32 bit integers.  We use this format since   *
+ *       it allows fast execution of multiplications and divisions.          *
+ *                                                                           *
+ *       "DPF" will refer to this special format in the following text.      *
+ *       See oper_32b.c                                                      *
+ *                                                                           *
+ *       The R[i] were normalized in routine AUTO (hence, R[i] < 1.0).       *
+ *       The K[i] and Alpha are theoretically < 1.0.                         *
+ *       The A[i], for a sampling frequency of 8 kHz, are in practice        *
+ *       always inferior to 16.0.                                            *
+ *                                                                           *
+ *       These characteristics allow straigthforward fixed-point             *
+ *       implementation.  We choose to represent the parameters as           *
+ *       follows :                                                           *
+ *                                                                           *
+ *               R[i]    Q31   +- .99..                                      *
+ *               K[i]    Q31   +- .99..                                      *
+ *               Alpha   Normalized -> mantissa in Q31 plus exponent         *
+ *               A[i]    Q27   +- 15.999..                                   *
+ *                                                                           *
+ *       The additions are performed in 32 bit.  For the summation used      *
+ *       to calculate the K[i], we multiply numbers in Q31 by numbers        *
+ *       in Q27, with the result of the multiplications in Q27,              *
+ *       resulting in a dynamic of +- 16.  This is sufficient to avoid       *
+ *       overflow, since the final result of the summation is                *
+ *       necessarily < 1.0 as both the K[i] and Alpha are                    *
+ *       theoretically < 1.0.                                                *

+## Media Testing ##
+---
+#### AMR-WB Encoder :
+The Amr-Wb Encoder Test Suite validates the amrwb encoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrwbEncoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/AmrwbEncoderTest/AmrwbEncoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrwbEncoderTest/AmrwbEncoderTest /data/local/tmp/
+```

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+ FUNCTION DESCRIPTION
+
+ Compute pixel values for a block in the current VOP. The prediction
+ values are generated by averaging pixel values in the previous VOP; the
+ block position in the previous frame is computed from the current block's
+ motion vector. The computed pixel values are then computed by adding the
+ prediction values to the block residual values.

+ FUNCTION DESCRIPTION
+
+ Summary:
+
+ This function performs motion compensated prediction for the case where
+ the motion vector points to a block outside the VOP. The function interpolates
+ the pixels that are outside the VOP using the boundary pixels for the block.
+ Once the values are interpolated, the pixel values are computed for a block
+ in the current VOP. The prediction values are generated by averaging pixel
+ values in the previous VOP; the block position in the previous frame is
+ computed from the current block's motion vector. The computed pixel values
+ are calculated by adding the prediction values to the block residual values.
+
+ Details:
+
+ First, this functions determines which VOP boundary(ies) the motion vector
+ is outside, i.e., left, right, top, bottom. xpos is compared to the left and
+ right boundaries; ypos is compared to the top and bottom boundaries. The number
+ of block pixels inside the the boundary in the x and y directions are stored
+ in endx and endy, respectively. If the entire block is inside the x or y
+ boundary, the respectively end is set to 0.
+
+ After the boundaries are tested, any pixels lying outside a boundary are
+ interpolated from the boundary pixels. For example, if the block is outside the
+ bottom boundary, boundary pixels alone the bottom of the VOP as used to
+ interpolated those pixels lying outside the bottom boundary. The interpolation
+ used is a simple column-wise or row-wise copy of the boundary pixels (inside the
+ block) depending on which boundary the block is outside. In our example, each
+ boundary pixel would be copied column-wise to the pixel beneath it. If the
+ block was outside right boundary, the boundary pixels would be copied row-wise
+ to the pixel to the right of it. If the block was outside both an x and y
+ boundary, the boundary pixels would be copied row-wise for the portion of the
+ block outside the x boundary, and column-wise for the portion of the block
+ outside the y boundary. And so on.
+
+ Once the pixel interpolation is complete, the motion compensated output values
+ (comp[]) are calculed from the motion compensated prediction (pred[])values and
+ the residual values (sh_d[]) of the current frame. The prediction values are
+ generated by averaging pixel values in the previous VOP; the block position in
+ the previous frame is computed from the current block's motion vector. The
+ computed pixel values are calculated by adding the prediction values to the
+ block residual values.

+ FUNCTION DESCRIPTION FOR idct
+
+ This function transforms an 8r8 image block from dequantized DCT coefficients
+ (F(u,v)) to spatial domain pirel values (f(r,y)) by performing the two
+ dimensional inverse discrete cosine transform (IDCT).
+
+         _7_ _7_      C(u) C(v)
+    f(r,y) = \   \  F(u,v)---- ----cos[(2r+1)*u*pi/16]cos[(2y+1)*v*pi/16]
+         /__ /__    2    2
+         u=0 v=0
+
+    where   C(i) = 1/sqrt(2)    if i=0
+        C(i) = 1        otherwise
+
+ 2-D IDCT can be separated as horizontal(row-wise) and vertical(column-wise)
+ 1-D IDCTs. Therefore, 2-D IDCT values are found by the following two steps:
+ 1. Find horizontal 1-D IDCT values for each row from 8r8 dequantized DCT
+    coefficients by row IDCT operation.
+
+          _7_        C(u)
+    g(r,v) =  \   F(u,v) ---- cos[(2r+1)*u*pi/16]
+          /__         2
+          u=0
+
+ 2. Find vertical 1-D IDCT values for each column from the results of 1
+    by column IDCT operation.
+
+              _7_        C(v)
+    f(r,y) =  \   g(r,v) ---- cos[(2y+1)*v*pi/16]
+          /__         2
+          v=0

+ FUNCTION DESCRIPTION
+
+ This function performs high level motion compensation on the luminance and
+ chrominance data. It sets up all the parameters required by the functions
+ that perform luminance and chrominance prediction and it initializes the
+ pointer to the post processing semaphores of a given block. It also checks
+ the motion compensation mode in order to determine which luminance or
+ chrominance prediction functions to call and determines how the post
+ processing semaphores are updated.

+## Media Testing ##
+---
+#### Mpeg4H263Decoder :
+The Mpeg4H263Decoder Test Suite validates the Mpeg4 and H263 decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m Mpeg4H263DecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/Mpeg4H263DecoderTest/Mpeg4H263DecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/Mpeg4H263DecoderTest/Mpeg4H263DecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/m4v_h263/dec/test/Mpeg4H263Decoder-1.1.zip).
+Download, unzip and push these files into device for testing.
+
+```
+adb push Mpeg4H263Decoder /data/local/tmp/
+```
+
+usage: Mpeg4H263DecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/Mpeg4H263DecoderTest -P /data/local/tmp/Mpeg4H263Decoder/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest Mpeg4H263DecoderTest -- --enable-module-dynamic-download=true
+```

+/** @introduction   Common Video Encoder Interface (CVEI) is intended to be used by
+    application developers who want to create a multimedia application with video
+    encoding feature. CVEI is designed such that new video encoder algorithms or
+    modules can be plugged in seamlessly without user interaction. In other words,
+    any changes to the CVEI library are transparent to the users. Users can still
+    use the same set of APIs for new encoding tools.
+
+    @requirement    CVEI will take an input frame in one of several format supported
+    by PV and encode it to an MPEG4 bitstream. It will also return a reconstructed
+    image in YUV 4:2:0 format. Currently the input format supported are YUV 4:2:0,
+    RGB24 and UYVY 4:2:2.
+
+    CVEI is designed such that it is simple to use. It should hides implementation
+    dependency  from the users. In this version, we decided that the operation will
+    be synchronous, i.e., the encoding will be a blocked call. Asynchronous operation
+    will be in the level above CVEI, i.e., in Author Engine Video Module which will
+    take care of capturing device as well.
+
+    @brief  The following classes are used to interface with codecs. Their names
+    are CPVxxxVideoEncoder where xxx is codec specific such as MPEG4, H263, H26L,
+    etc. All of them are subclasses of CPVCommonVideoEncoder.

+ REVISION HISTORY
+ Who:   Date: July/2001
+ Description:   1. Optimized BlockIDCT bitmap checking.
+                2. Rearranged functions.
+                3. Do column IDCT first, then row IDCT.
+                4. Combine motion comp and IDCT, require
+                   two sets of row IDCTs one for INTRA
+                   and one for INTER.
+                5. Add AAN IDCT
+
+ Who:   Date: 8/16/01
+                1. Increase the input precision to 8 bits, i.e. change RDCTBITS
+                   to 11, have to comment out all in-line assembly since 16 bit
+                    multiplication doesn't work. Try to use diffent precision with
+                    32 bit mult. but hasn't finished. Turns out that without in-line
+                    assembly the performance doesn't change much (only 1%).
+ Who:   Date: 9/04/05
+                1. Replace AAN IDCT with Chen's IDCT to accommodate 16 bit data type.

+ Function: BlckQuantDequantH263
+ Date:     June 15, 1999
+ Purpose:  Combine BlockQuantH263 and BlockDequantH263ENC
+ Input:   coeff=> DCT coefficient
+ Output:  qcoeff=> quantized coefficient
+          rcoeff=> reconstructed coefficient
+          return CBP for this block
+          4/2/01,  correct dc_scaler for short_header mode.
+          5/14/01,
+          changed the division into LUT multiplication/shift and other
+          modifications to speed up fastQuant/DeQuant (check for zero 1st, rowq LUT,
+          fast bitmaprow mask and borrowed Addition method instead of ifs from , ).
+          6/25/01,
+          Further optimization (~100K/QCIF), need more testing/comment before integration.
+
+          7/4/01,  break up Inter / Intra function and merge for different cases.
+          7/22/01,  combine AAN scaling here and reordering.
+          7/24/01, , reorder already done in FDCT, the input here is in the next block and
+            it's the
+            transpose of the raster scan. Output the same order (for proof of concenpt).
+          8/1/01, , change FDCT to do row/column FDCT without reordering, input is still
+            in the next block. The reconstructed DCT output is current block in normal
+            order. The quantized output is in zigzag scan order for INTER, row/column for
+            INTRA. Use bitmapzz for zigzag RunLevel for INTER.  The quantization is done
+            in column/row scanning order.
+          8/2/01, , change IDCT to do column/row, change bitmaprow/col to the opposite.
+          8/3/01, , add clipping to the reconstructed coefficient [-2047,2047]
+          9/4/05, , removed scaling for AAN IDCT, use Chen IDCT instead.

+
+#### Mpeg4H263Encoder :
+The Mpeg4H263Encoder Test Suite validates the Mpeg4 and H263 encoder available in libstagefright.
+Run the following steps to build the test suite:
+```
+m Mpeg4H263EncoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/Mpeg4H263EncoderTest/Mpeg4H263EncoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/Mpeg4H263EncoderTest/Mpeg4H263EncoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/m4v_h263/enc/test/Mpeg4H263Encoder.zip ) Download, unzip and push these files into device for testing.
+
+```
+adb push Mpeg4H263Encoder/. /data/local/tmp/
+```
+
+usage: Mpeg4H263EncoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/Mpeg4H263EncoderTest -P /data/local/tmp/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest Mpeg4H263EncoderTest -- --enable-module-dynamic-download=true
+```

+# Fuzzer for libstagefright_m4vh263dec decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for MPEG4/H263 is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+Dict files (dictionary files) are created for MPEG4 and H263 to ensure that the required start
+bytes are present in every input file that goes to the fuzzer.
+This ensures that decoder does not reject any input file in the first check
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec using a loop.
+ * If the decode operation was successful, the input is advanced by the number of bytes consumed
+   in the decode call.
+ * If the decode operation was un-successful, the input is advanced by 1 byte so that the fuzzer
+   can proceed to feed the next frame.
+
+This ensures that the plugin tolerates any kind of input (empty, huge, malformed, etc)
+and doesnt `exit()` on any input and thereby increasing the chance of identifying vulnerabilities.
+
+##### Other considerations
+ * Two fuzzer binaries - mpeg4_dec_fuzzer and h263_dec_fuzzer are generated based on the presence
+   of a flag - 'MPEG4'
+ * The number of decode calls are kept to a maximum of 100 so that the fuzzer does not timeout.
+
+## Build
+
+This describes steps to build mpeg4_dec_fuzzer and h263_dec_fuzzer binary.
+
+### Android
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) mpeg4_dec_fuzzer
+  $ mm -j$(nproc) h263_dec_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some MPEG4 or H263 files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/mpeg4_dec_fuzzer/mpeg4_dec_fuzzer CORPUS_DIR
+  $ adb shell /data/fuzz/arm64/h263_dec_fuzzer/h263_dec_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/mpeg4_dec_fuzzer/mpeg4_dec_fuzzer CORPUS_DIR
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/h263_dec_fuzzer/h263_dec_fuzzer CORPUS_DIR

+# Fuzzer for libstagefright_m4vh263enc encoder
+
+## Plugin Design Considerations
+The fuzzer plugin for MPEG4/H263 is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+MPEG4/H263 supports the following parameters:
+1. Frame Width (parameter name: `encWidth`)
+2. Frame Height (parameter name: `encHeight`)
+3. Rate control mode (parameter name: `rcType`)
+4. Number of bytes per packet (parameter name: `packetSize`)
+5. Qp for I-Vop(parameter name: `iQuant`)
+6. Qp for P-Vop (parameter name: `pQuant`)
+7. Enable RVLC mode (parameter name: `rvlcEnable`)
+8. Quantization mode (parameter name: `quantType`)
+9. Disable frame skipping (parameter name: `noFrameSkipped`)
+10. Enable scene change detection (parameter name: `sceneDetect`)
+11. Number of intra MBs in P-frame(parameter name: `numIntraMB`)
+12. Search range of ME (parameter name: `searchRange`)
+13. Enable 8x8 ME and MC (parameter name: `mv8x8Enable`)
+14. Enable AC prediction (parameter name: `useACPred`)
+15. Threshold for intra DC VLC (parameter name: `intraDCVlcTh`)
+16. Encoding Mode (parameter name: `encMode`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `rcType` | 0. `CONSTANT_Q` 1. `CBR_1` 2. `VBR_1` 3. `CBR_2` 4. `VBR_2` 5. `CBR_LOWDELAY` | All the bits of 6th byte of data modulus 6 |
+| `packetSize` | In the range `0 to 255` | All the bits of 7th byte of data |
+| `iQuant` | In the range `1 to 31` | All the bits of 8th byte of data |
+| `pQuant` | In the range `1 to 31` | All the bits of 9th byte of data |
+| `rvlcEnable` | 0. `PV_OFF` 1. `PV_ON` | bit 0 of 10th byte of data |
+| `quantType` | 0. `0` 1. `1` | bit 0 of 11th byte of data |
+| `noFrameSkipped` | 0. `PV_OFF` 1. `PV_ON` | bit 0 of 12th byte of data |
+| `sceneDetect` | 0. `PV_OFF` 1. `PV_ON` | bit 0 of 13th byte of data |
+| `numIntraMB` | In the range `0 to 7` | bit 0, 1 and 2 of 14th byte of data |
+| `searchRange` | In the range `0 to 31` | bit 0, 1, 2, 3 and 4 of 15th byte of data |
+| `mv8x8Enable` | 0. `PV_OFF` 1. `PV_ON` | bit 0 of 16th byte of data |
+| `useACPred` | 0. `PV_OFF` 1. `PV_ON` | bit 0 of 17th byte of data |
+| `intraDCVlcTh` | In the range `0 to 7` | bit 0, 1 and 2 of 18th byte of data |
+
+Following parameters are only for mpeg4_enc_fuzzer
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `encWidth` | In the range `0 to 10239` | All the bits of 1st and 2nd byte of data |
+| `encHeight` | In the range `0 to 10239` | All the bits of 3rd and 4th byte of data |
+| `encMode` | 0. `H263_MODE` 1. `H263_MODE_WITH_ERR_RES` 2. `DATA_PARTITIONING_MODE` 3. `COMBINE_MODE_NO_ERR_RES` 4. `COMBINE_MODE_WITH_ERR_RES` | All the bits of 19th byte of data modulus 5 |
+
+Following parameters are only for h263_enc_fuzzer
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `encWidth` | 0. `128` 1. `176` 2. `352` 3. `704` 4. `1408` | All the bits of 1st byte of data modulus 5|
+| `encHeight` | 0. `96` 1. `144` 2. `288` 3. `576` 4. `1152 ` | All the bits of 3rd byte of data modulus 5|
+| `encMode` | 0. `SHORT_HEADER` 1. `SHORT_HEADER_WITH_ERR_RES` | All the bits of 19th byte of data modulus 2 |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec using a loop.
+If the encode operation was successful, the input is advanced by the frame size.
+If the encode operation was un-successful, the input is still advanced by frame size so
+that the fuzzer can proceed to feed the next frame.
+
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+# Fuzzer for libstagefright_mp3dec decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for mp3 decoder is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+
+This fuzzer makes use of the following config parameters:
+1. Equalizer type (parameter name: `equalizerType`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `equalizerType` | 0. `flat ` 1. `bass_boost ` 2. `rock ` 3. `pop ` 4. `jazz ` 5. `classical ` 6. `talk ` 7. `flat_ ` | Bits 0, 1 and 2 of first byte of input stream |
+| `crcEnabled` | 0. `false ` 1. `true `| Bit 0 of second byte of input stream |
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec using a loop.
+ * If the decode operation was successful, the input is advanced by the number
+   of bytes used by the decoder.
+ * If the decode operation was un-successful, the input is advanced by 1 byte
+   till it reaches a valid frame or end of stream.
+
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build mp3_dec_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) mp3_dec_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some mp3 files to that folder.
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/mp3_dec_fuzzer/mp3_dec_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/mp3_dec_fuzzer/mp3_dec_fuzzer CORPUS_DIR
+```

+Input
+    pExt = pointer to the external interface structure. See the file
+           pvmp3decoder_api.h for a description of each field.
+           Data type of pointer to a tPVMP3DecoderExternal
+           structure.
+
+    pMem = void pointer to hide the internal implementation of the library
+           It is cast back to a tmp3dec_file structure. This structure
+           contains information that needs to persist between calls to
+           this function, or is too big to be placed on the stack, even
+           though the data is only needed during execution of this function
+           Data type void pointer, internally pointer to a tmp3dec_file
+           structure.
+
+
+ Outputs:
+     status = ERROR condition.  see structure  ERROR_CODE
+
+ Pointers and Buffers Modified:
+    pMem contents are modified.
+    pExt: (more detail in the file pvmp3decoder_api.h)
+    inputBufferUsedLength - number of array elements used up by the stream.
+    samplingRate - sampling rate in samples per sec
+    bitRate - bit rate in bits per second, varies frame to frame.

+ FUNCTION DESCRIPTION
+
+    The frequency lines are preprocessed by the "alias reduction" scheme
+    and fed into the IMDCT matrix, each 18 into one transform block.
+    The first half of the output values are added to the stored overlap
+    values from the last block. These values are new output values and
+    are input values for the polyphase filterbank. The second half of the
+    output values is stored for overlap with the next data granule.
+    The number of windowed samples is 12 for short blocks, and 36 for long
+    blocks
+
+Windowing
+
+    Depending on window_switching_flag[gr][ch], block_type[gr][ch] and
+    mixed_block_flag[gr][ch] different shapes of windows are used.
+        normal window
+        start window
+        stop window
+        short windows
+            Each of the three short blocks is windowed separately.
+            The windowed short blocks must be overlapped and concatenated.
+
+Overlapping and adding with previous block
+
+    The first half (18 values) of the current block (36 values) has to be
+    overlapped with the second half of the previous block. The second half
+    of the current block has to be stored for overlapping with the next block

+ FUNCTION DESCRIPTION
+
+    stereo processing for mpeg1 layer III
+    After requantization, the reconstructed values are processed for ms_stereo
+    or intensity_stereo modes or both, before passing them to the synthesis
+    filterbank
+
+    In ms_stereo mode the values of the normalized middle/side channels
+    M[l] and S[l] are transmitted instead of the left/right channel values
+    L[l] and R[l]. From here, L[l] and R[l] are reconstructed
+
+    Intensity_stereo is done by specifying the magnitude (via the
+    scalefactors of the left channel) and a stereo position is_pos[sfb],
+    which is transmitted instead of scalefactors of the right channel.
+    The stereo position is used to derive the left and right channel signals

+
+Run the following steps to build the test suite:
+```
+m Mp3DecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/Mp3DecoderTest/Mp3DecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/Mp3DecoderTest/Mp3DecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/mp3dec/test/Mp3DecoderTest.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push Mp3DecoderTestRes/. /data/local/tmp/
