Ari Lemmetti 9407610555 Moved DCT / DST matrices to dct-generic.c 2014-10-02 13:24:30 +03:00
Ari Lemmetti 7255112bd8 Added transposed DCT/DST tables. Use them while calculating transforms instead of doing runtime transpose. Added separate functions for DST and IDST. 2014-10-02 13:24:30 +03:00
Ari Lemmetti e7bcb58846 Added 32x32 IDCT 2014-10-02 13:24:30 +03:00
Ari Lemmetti eacf173b7e Added 32x32 DCT for AVX2 2014-10-02 13:24:30 +03:00
Ari Lemmetti d2856a5d40 Added 32x32 transpose 2014-10-02 13:24:30 +03:00
Ari Lemmetti 7a33f08312 Added 16x16 DCT and IDCT for AVX2 2014-10-02 13:24:30 +03:00
Ari Lemmetti d2fe2a5391 Added 16x16 transpose 2014-10-02 13:24:30 +03:00
Ari Lemmetti d6af146a2e Added part of the functions 16x16 DCT needs 2014-10-02 13:24:30 +03:00
Ari Lemmetti aba3acdfff Added AVX2 optimized transforms for 4x4 and 8x8 blocks 2014-10-02 13:24:30 +03:00
Ari Lemmetti 41b032664d First version of 4x4 forward DCT 2014-10-02 13:24:29 +03:00
Laurent Fasnacht f1b303a2d2 Fix compilation errors 2014-08-11 09:53:06 +02:00
Ari Lemmetti 0beb278f5b Partial butterfly strategy is now called DCT strategy. Made changes to transform functions in preparation for optimizations. 
-Moved fast_forward_dst and fast_inverse_dst to DCT strategies
 2014-07-31 13:25:28 +03:00
Ari Lemmetti 6bf63bd171 Added AVX2 strategy for partial butterfly (no optimizations yet) 2014-07-31 13:25:28 +03:00
Ari Koivula 669e99dd7f Improve intra SAD AVX2 intrinsics. 
- Moved implementations for different sizes to inline functions that are
  defined using each other, reducing the amount of redundant code.

- Performance of sad_8bit_32x32_avx2 improved by about 10% due to unrolling of
  the loop.

Ari Koivula a8f7103797 Add AVX2 implementations for sad_8bit_ 8x8, 16x16 and 32x32. 2014-07-18 18:27:30 +03:00
