2013-02-13WIP: ssse3 version of convolve avg functionsScott LaVarnway
Initial ssse3 convolve avg functions and is one step closer to using x86inc.asm. The decoder performance improved by 8% for the test clip used. This should be revisited later to see if averaging outside the loop is better than having many similar filter functions. Change-Id: Ice3fafb423b02710b0448ffca18b296bcac649e9
2013-02-09Bug fix: ssse3 version of subpixel did not match C codeScott LaVarnway
A 16 bit overflow condition occurs when using the EIGHTTAP_SMOOTH filters. (vp9_sub_pel_filters_8lp) Changed the order of the adds to fix this problem. Also added ssse3 support for 4x4 subpixel filtering. Change-Id: I475eaadae920794c2de5e01e9735c059a856518e

* changes: Restore SSSE3 subpixel filters in new convolve framework Convert subpixel filters to use convolve framework Add 8-tap generic convolver
2013-02-08Restore SSSE3 subpixel filters in new convolve frameworkJohn Koleszar
This commit adds the 8 tap SSSE3 subpixel filters back into the code underneath the convolve API. The C code is still called for 4x4 blocks, as well as compound prediction modes. This restores the encode performance to be within about 8% of the baseline. Change-Id: Ife0d81477075ae33c05b53c65003951efdc8b09c

2013-02-05Convert subpixel filters to use convolve frameworkJohn Koleszar
Update the code to call the new convolution functions to do subpixel prediction rather than the existing functions. Remove the old C and assembly code, since it is unused. This causes a 50% performance reduction on the decoder, but that will be resolved when the asm for the new functions is available. There is no consensus for whether 6-tap or 2-tap predictors will be supported in the final codec, so these filters are implemented in terms of the 8-tap code, so that quality testing of these modes can continue. Implementing the lower complexity algorithms is a simple exercise, should it be necessary. This code produces slightly better results in the EIGHTTAP_SMOOTH case, since the filter is now applied in only one direction when the subpel motion is only in one direction. Like the previous code, the filtering is skipped entirely on full-pel MVs. This combination seems to give the best quality gains, but this may be indicative of a bug in the encoder's filter selection, since the encoder could achieve the result of skipping the filtering on full-pel by selecting one of the other filters. This should be revisited. Quality gains on derf positive on almost all clips. The only clip that seemed to be hurt at all datarates was football (-0.115% PSNR average, -0.587% min). Overall averages 0.375% PSNR, 0.347% SSIM. Change-Id: I7d469716091b1d89b4b08adde5863999319d69ff

2012-11-28Further improve macroblock loop filtersYunqing Wang
This change included: 1. Aligned reads in vp9_mbloop_filter_vertical_edge function. Since we actually read 16 bytes, we can align the reads to read starting at (s - 8) instead of (s - 5). 2. Combined u, v loop filters. 3. Added 8x16 transpose. This gave 2% decoder performance gain (tulip clip). Change-Id: Ib14c2f1645c4a3436df17fe2f24789506bf0bb58

2012-11-26Improve sad3x16 SSE2 functionYunqing Wang
Vp9_sad3x16_sse2() is heavily called in decoder, in which the unaligned reads consume lots of cpu cycles. When CONFIG_SUBPELREFMV is off, the unaligned offset is 1. In this situation, we can adjust the src_ptr to be 4-byte aligned, and then do the aligned reads. This reduced the reading time significantly. Tests on 1080p clip showed over 2% decoder performance gain with CONFIG_SUBPELREFM off. Change-Id: I953afe3ac5406107933ef49d0b695eafba9a6507
