2014-02-14SSSE3 convolution optimizationlevytamar82
Optimizing all SSSE3 assembly for convolution: 1. vp9_filter_block1d4_h8_sse2 2. vp9_filter_block1d8_h8_sse2 3. vp9_filter_block1d16_h8_sse2 4. vp9_filter_block1d4_v8_sse2 5. vp9_filter_block1d8_v8_sse2 6. vp9_filter_block1d16_v8_sse2 my optimization include: -processing 2x8 elements in one 128 bit register instead of processing 8 elements in one 128 bit register. -removing unecessary loads. This optimization gives between 2.4% user level gain for 480p input and 1.6% user level gain for 720p. This Optimization is done only for 64 bit Change-Id: Ic07fce2f9360329b4f2d956efda1480ae958766b
2014-02-12AVX2 Convolve Optimizationlevytamar82
Two convolve functions were optimized for AVX2: 1. vp9_filter_block1d16_h8 2. vp9_filter_block1d16_v8 vp9_filter_block1d16_v8 was optimized for AVX2 by reducing the number of loop strides by half, two strides were processed in parallel. vp9_filter_block1d16_v8 was also optimized in the same way also some of the loads were being done outside of the loop and by that preventing redundant loads. This Optimization gives 43% function level gain and 1.3% user level gain. Now can be compiled in Windows Change-Id: I2714124cfb0c14a77d7a0ce126a20db92ffbf92c

2014-01-08Optimze inv 16x16 DCT with 10 non-zero coeffs - P1Jingning Han
This commit is the first patch optimizing SSE2 implementation of inverse 16x16 DCT with <10 non-zero coefficients. It focused on the first 1-D (row) transformation. It exploits the fact that only top-left 4x4 block contains non-zero coefficients, in a 2-D inverse 16x16 DCT with <10 coeffients. The average runtime of idct16x16_10 unit is reduced from 883 cycles -> 779 cycles (12% faster). For pedestrian_area_1080p 300 frames at 4000 kbps, the speed 2 runtime goes down from 310651 ms -> 305910 ms. The decoding speed goes up from 80.37 fps -> 80.87 fps.

This commit merges the initial buffer swap operations in idct8_1d_sse2 into the array transpose step, hence reducing number of instructions therein. Change-Id: I219f6f50813390d2ec3ee37eecf2a4a2b44ae479
2014-01-03Rework idct8x8_10 SSE2 implementationJingning Han
This commit optimizes the SSE2 implmentation of idct8x8_10. It exploits the fact that only top-left 4x4 block contains non-zero coefficients, and hence reduces the instructions needed. The runtime of idct8x8_10_sse2 goes down from 216 to 198 CPU cycles, estimated by averaging over 100000 runs. For pedestrian_area_1080p 300 frames coded at 4000kbps, the average decoding speed goes up from 79.3 fps to 79.7 fps. Change-Id: I6d277bbaa3ec9e1562667906975bae06904cb180

The performance gain of idct16x16_10_add_sse2 function is not noticeable. However since both functions use the IDCT16_1D, idct16x16_10_add_sse2 should be modified as well. Tested with: park_joy_420_720p50.y4m Change-Id: I02b957e36fcf997c677d15baf496533895271bff

2013-11-22Do vertical loopfiltering in parallelYunqing Wang
This patch followed "Add filter_selectively_vert_row2 to enable parallel loopfiltering" commit, and added x86 SSE2 optimization to do 16-pixel filtering in parallel. For other optimizations (neon and dspr2), current 16-pixel functions were done by calling 8-pixel functions twice, and real 16-pixel functions could be added later. Decoder speedup: tulip clip: 2% speed gain; old_town_cross: 1.2% speed gain; bus: 2% speed gain. Change-Id: I4818a0c72f84b34f5fe678e496cf4a10238574b7

2013-11-19Fix decoder mismatch with ssse3 enabledYunqing Wang
This patch fixed issue 661: "Decoder produces mismatched outputs with ssse3 enabled and disabled." In sub-pixel filters, a pixel value was multiplied by a filter coefficient, and the results were added up. The order of adding up these multiplications had to be arranged carefully to prevent incorrect overflowing. Change-Id: Id08af4200fea9e1b896fc40157b8651c2c7e80f2

2013-11-15Do horizontal loopfiltering in parallelYunqing Wang
This patch followed "Rewrite filter_selectively_horiz for parallel loopfiltering" commit, and added x86 SSE2 optimization to do 16-pixel filtering in parallel. Also, corrected the declaration of aligned arrays. For 8-pixel-in-parallel case, improved the calculation of the masks and filters. Updated the threshold loading since the thresholds were already duplicated. Updated neon C functions to call neon loopfilters twice. Using tulip clip, tests showed it gave a ~1.5% decoder speed gain.
