2013-04-18convolve: support larger blocks, fix asm saturation bugJohn Koleszar
Updates the common convoloution code to support blocks larger than 16x16, and rectangular blocks. This uncovered a bug in the SSSE3 filtering routines due to the order of application of saturation. This commit fixes that bug, adjusts the unit test to bias its random values towards the extremes, and adds a test to ensure that all filters conform to the expected pairwise addition structure.

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

2013-02-26Optimize vp9_dc_only_idct_add_c functionYunqing Wang
Wrote SSE2 version of vp9_dc_only_idct_add_c function. In order to improve performance, clipped the absolute diff values to [0, 255]. This allowed us to keep the additions/subtractions in 8 bits. Test showed an over 2% decoder performance increase. Change-Id: Ie1a236d23d207e4ffcd1fc9f3d77462a9c7fe09d
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

* 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
