* rv40dsp x86: MMX/MMX2/3DNow/SSE2/SSSE3 implementations of MCChristophe Gisquet2012-05-10
| | | | | | | | | | | | | | | | | | | | Code mostly inspired by vp8's MC, however: - its MMX2 horizontal filter is worse because it can't take advantage of the coefficient redundancy - that same coefficient redundancy allows better code for non-SSSE3 versions Benchmark (rounded to tens of unit): V8x8 H8x8 2D8x8 V16x16 H16x16 2D16x16 C 445 358 985 1785 1559 3280 MMX* 219 271 478 714 929 1443 SSE2 131 158 294 425 515 892 SSSE3 120 122 248 387 390 763 End result is overall around a 15% speedup for SSSE3 version (on 6 sequences); all loop filter functions now take around 55% of decoding time, while luma MC dsp functions are around 6%, chroma ones are 1.3% and biweight around 2.3%.
