2015-08-04Replace vp9_ prefix with vpx_ prefix in vpx_dsp function namesJingning Han
This commit clears the function naming convention in vpx_dsp. It replaces vp9_ prefix of global functions with vpx_ prefix. It also removes the vp9_ prefix from static functions. Change-Id: I6394359a63b71a51dda01342eec6a3cc08dfeedf

2015-07-20Unify the high bit-depth forward hybrid transformsJingning Han
The SSE2 version high bit-depth forward hybrid transforms are essentially using the C functions via cross referencing to 1-D functions in vp9_dct.c. This commit unifies the two versions and removes the unnecessary dependency. Change-Id: Ib4d0702a138f8daf7d0bd97c141ee7088f293765

2015-06-01mips msa vp9 updated idct 8x8, 16x16 and 32x32 moduleParag Salasakar
Updated sources according to improved version of common MSA macros. Enabled idct MSA hooks and tests. Overall, this is just upgrading the code with styling changes. Change-Id: I1f488ab2c741f6c622b7a855388a202168082209

2015-05-29mips msa vp9 updated macros and disable all MSA functionsParag Salasakar
Done little restructuring/styling changes to the sources like generic macro definitions, their use to reduce code lines, better code alignments etc. Disabled all MSA hooks and tests Change-Id: Ic6f2dce0b501f46b80c06c46c0fe2043d557b190
2015-05-22Re-worked header filesScott LaVarnway
Various header/test files had to be re-worked in order to build "Remove cm parameter from vp9_decode_block_tokens()". This patch reverts the "Remove cm" part and only contains the re-worked header files. Change-Id: I520958a88d1991fee988a3c784d0eac40e117a32
2015-05-13Relocate memory operations for common codeJohann
With the sad functions, and hopefully the variance functions soon, moving to the vpx_dsp location, place the defines used in the reference C code in a common location. Change-Id: I4c8ce7778eb38a0a3ee674d2f1c488eda01cfeca
2015-05-07replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNEDJames Zern
this macro was used inconsistently and only differs in behavior from DECLARE_ALIGNED when an alignment attribute is unavailable. this macro is used with calls to assembly, while generic c-code doesn't rely on it, so in a c-only build without an alignment attribute the code will function as expected. Change-Id: Ie9d06d4028c0de17c63b3a27e6c1b0491cc4ea79

2014-12-02Added high bitdepth sse2 transform functionsPeter de Rivaz
Also removes some spurious changes in common/vp9_blockd.h which was introduced by a rebase issue between nextgen and master branches. Change-Id: If359f0e9a71bca9c2ba685a87a355873536bb282 (cherry picked from commit 005d80cd05269a299cd2f7ddbc3d4d8b791aebba) (cherry picked from commit 08d2f548007fd8d6fd41da8ef7fdb488b6485af3) (cherry picked from commit 4230c2306c194c058f56433a5275aa02a2e71d56)
2014-10-09Rename highbitdepth functions to use highbd prefixDeb Mukherjee

Bit-stream clarification related to Issue 868. Change-Id: I92a7bc5b7782c9ea5c3f6cceec761742183c9514
2014-10-03Incorporate WRAPLOW macro into non-highbitdepth txDeb Mukherjee
Incorporates the WRAPLOW macro into the non-highbitdepth transforms to aid hardware verification between a software C model and an intended hardware implementation though the use of the configure options: --enable-experimental --enable-emulate-hardware. Note that to avoid further discrepancies between the sse/sse2 implementations of the transforms and the C implementation, when the emulate hardware option is invoked, we also disable sse/sse2/etc. Also incudes some minor cleanups/renaming etc. Change-Id: Ib864d8493313927d429cce402982f1c8e45b3287
2014-09-11Adds high bitdepth transform functions and testsDeb Mukherjee
Adds various high bitdepth transform functions and tests. Much of the changes are related to using typedefs tran_low_t and tran_high_t for the final transform cofficients and intermediate stages of the transform computation respectively rather than fixed types int16_t/int. When vp9_highbitdepth configure flag is off, these map tp int16_t/int32_t, but when the flag is on, they map to int32_t/int64_t to make space for needed extra precision.

2014-07-10tests: add API_REGISTER_STATE_CHECKJames Zern
used to wrap API functions to ensure full environment consistency as opposed to the renamed ASM_REGISTER_STATE_CHECK which is used with assembly functions. currently checks the FPU tag word in x86/x86_64 gcc builds to ensure emms has been called. Change-Id: Ie241772dbf903d33d516a1add4c8c6783f2e1490

2014-06-03Rework unit test for 8x8 transformationJingning Han
This commit reworks the unit test for 8x8 forward/inverse transformation. It adds extreme input value test to detect overflow issues in the intermediate steps. It temporarily disables unit test for the SSSE3 version, which showed overflow failure in the new test conditions. Change-Id: I7caf10bba4b6db031add65d8c0eb99426b38aa42
2014-05-30Add overflow check unit test for 16x16 inverse DCT/ADST transformJingning Han

Change-Id: I68034a6126b45192c87d8c642155290e89bff8fa
2014-05-23Re-enable unit test on neon implementation of 16x16 idctJingning Han
The previous change only tunes forward transform. It doesn't affect the neon implementation of the inverse transform. Hence turn the unit test on. Change-Id: I4f0f43783b98814d1eee53182209f9669d538140
