Sindre Aamås b43e58a366 [Processing/x86] Add an AVX2 implementation of GeneralBilinearFastDownsample ... Keep track of relative pixel offsets and utilize pshufb to efficiently extract relevant pixels for horizontal scaling ratios <= 8. Because pshufb does not cross 128-bit lanes, the overhead of address calculations and loads is relatively greater as compared with an SSSE3 implementation. Fall back to a generic approach for ratios > 8. The implementation assumes that data beyond the end of each line, before the next line begins, can be dirtied; which AFAICT is safe with the current usage of these routines. Speedup is ~10.42x/~5.23x (32-bit/64-bit) for horizontal ratios <= 2, ~9.49x/~4.64x for ratios within (2, 4], ~6.43x/~3.18x for ratios within (4, 8], and ~5.42x/~2.50x for ratios > 8 when not memory-bound on Haswell as compared with the current SSE2 implementation.		2016-05-23 20:23:47 +02:00
