2013-06-26fixed a compiling problem with MSVC win32 buildYaowu Xu
The aligned array in parameter list caused win32 build to report c2719 error. This commit fixed the issue by make the parameter type a pointer instead of an array. Change-Id: I4ed654ce4eba2db4995d9cdc136c68e9a6acc992

2013-06-25Add averaging-SAD functions for 8-point comp-inter motion search.Ronald S. Bultje
Makes first 50 frames of bus @ 1500kbps encode from 3min22.7 to 3min18.2, i.e. 2.3% faster. In addition, use the sub_pixel_avg functions to calc the variance of the averaging predictor. This is slightly suboptimal because the function is subpixel-position-aware, but it will (at least for the SSE2 version) not actually use a bilinear filter for a full-pixel position, thus leading to approximately the same performance compared to if we implemented an actual average-aware full-pixel variance function. That gains another 0.3 seconds (i.e. encode time goes to 3min17.4), thus leading to a total gain of 2.7%. Change-Id: I3f059d2b04243921868cfed2568d4fa65d7b5acd

This commit makes use of the butterfly structure to enable the sse2 version implementation of 8x8 ADST/DCT hybrid transform coding. The runtime of hybrid transform module goes down from 1170 cycles to 245 cycles. Overall speed-up around 1.5%. Change-Id: Ic808ffd21ece8a9d0410d8c0243d7b6c28ac3b3f

2013-06-21Implement SSE2 block_error.Ronald S. Bultje
Change vp9_block_error() to return a 64bit error variable, change all callers to expect a 64bit return value (this will prevent overflows, which we basically don't check for at all right now). Remove duplicate block_error() function, which fixed that through truncation. Remove old (incompatible) mmx/sse2 block_error SIMD versions and replace with a new one that returns a 64bit value. Encoding time of first 50 frames of bus @ 1500kbps goes from 3min29 to 3min23, i.e. a 3% overall speedup. Change-Id: Ib71ac5508b5ee8a80f1753cd85d72df1629abe68

3% faster overall (3min35.0 to 3min28.5). Change-Id: I5ff8a5c2c91586b6632ca5009ad1ea51ce94af5e
2013-06-20SSE2/SSSE3 optimizations and unit test for sub_pixel_avg_variance().Ronald S. Bultje
Encoding of bus @ 1500kbps (first 50 frames) goes from 3min57 to 3min35, i.e. approximately a 10.5% speedup. Note that the SIMD versions which use a bilinear filter (x_offset & 7 || y_offset & 7) aren't perfectly interleaved, and can probably be improved further in the future. I've marked this with a few TODOs/FIXMEs in the code. Change-Id: I5c9e900c0f0d32e431a50fecae213b510b2549f9
2013-06-20Implement sse2 and ssse3 versions for all sub_pixel_variance sizes.Ronald S. Bultje
Overall speedup around 5% (bus @ 1500kbps first 50 frames 4min10 -> 3min58). Specific changes to timings for each function compared to original assembly-optimized versions (or just new version timings if no previous assembly-optimized version was available): sse2 4x4: 99 -> 82 cycles sse2 4x8: 128 cycles sse2 8x4: 121 cycles sse2 8x8: 149 -> 129 cycles sse2 8x16: 235 -> 245 cycles (?) sse2 16x8: 269 -> 203 cycles sse2 16x16: 441 -> 349 cycles sse2 16x32: 641 cycles sse2 32x16: 643 cycles sse2 32x32: 1733 -> 1154 cycles sse2 32x64: 2247 cycles sse2 64x32: 2323 cycles sse2 64x64: 6984 -> 4442 cycles ssse3 4x4: 100 cycles (?) ssse3 4x8: 103 cycles ssse3 8x4: 71 cycles ssse3 8x8: 147 cycles ssse3 8x16: 158 cycles ssse3 16x8: 188 -> 162 cycles ssse3 16x16: 316 -> 273 cycles ssse3 16x32: 535 cycles ssse3 32x16: 564 cycles ssse3 32x32: 973 cycles ssse3 32x64: 1930 cycles ssse3 64x32: 1922 cycles ssse3 64x64: 3760 cycles Change-Id: I81ff6fe51daf35a40d19785167004664d7e0c59d

2013-04-10Make RD superblock mode search size-agnostic.Ronald S. Bultje
Merge various super_block_yrd and super_block_uvrd versions into one common function that works for all sizes. Make transform size selection size-agnostic also. This fixes a slight bug in the intra UV superblock code where it used the wrong transform size for txsz > 8x8, and stores the txsz selection for superblocks properly (instead of forgetting it). Lastly, it removes the trellis search that was done for 16x16 intra predictors, since trellis is relatively expensive and should thus only be done after RD mode selection. Gives basically identical results on derf (+0.009%). Change-Id: If4485c6f0a0fe4038b3172f7a238477c35a6f8d3
2013-04-04Move qcoeff, dqcoeff from BLOCKD to per-plane dataJohn Koleszar

2013-03-18Optimize 8x8 idct functionYunqing Wang
Wrote sse2 functions of vp9_short_idct8x8 and vp9_short_idct10_8x8. Compared to c version, the sse2 version is 2X faster. The decoder test didn't show noticeable gain since 8x8 idct doesn't take much of decoding time (less than 1% in my test). Change-Id: I56313e18cd481700b3b52c4eda5ca204ca6365f3
