2013-11-26Fix 16 wide neon horz loopfilter.Frank Galligan
Multiply by 3 was on 8bit vectors when it should have been on 16bit vectors. Change-Id: I248c1429b3134dfd171dfab0ebb109fd2437e1fc
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
2013-11-21Revert "Add 16 wide neon horz loopfilter."Frank Galligan
The change caused mismatches with some test vectors on neon. Original CL: https://gerrit.chromium.org/gerrit/#/c/67863/ Change-Id: I913891636d53783e93cb1865ca78ded1821dc4b0
2013-11-21Add 16 wide neon horz loopfilter.Frank Galligan
Add support to do 16 pixel horizontal filtering in Neon. Nexus devices saw about 0.5% decode speed increase. Change-Id: I2993f6c2d49f31fa74976879eeaa289fd3f4e15d
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.
