Pauli Oikkonen	6d43759604	Create a border-respecting 32-wide AVX hor_sad	2019-03-07 18:01:22 +02:00
Pauli Oikkonen	f218cecb38	Remove offending hor_sad_avx2_w32 function ... Consider possibly creating a non-offending AVX2 version instead, the way hor_sad_sse41_w32 works. Or maybe there's more essential work to do.	2019-03-05 22:51:41 +02:00
Pauli Oikkonen	d8b8923028	Add LGPL notices to reg_sad headers	2019-02-18 17:52:47 +02:00
Pauli Oikkonen	2d05ca8520	Remove width from constant-width hor_sad func params ... They should kinda know it already	2019-02-04 20:41:40 +02:00
Pauli Oikkonen	dd7d989a39	Implement 32-wide hor_sad on AVX2	2019-02-04 20:41:40 +02:00
Pauli Oikkonen	cbca3347b5	Unroll 64-wide AVX2 SAD by 2	2019-02-04 20:41:40 +02:00
Pauli Oikkonen	84cf771dea	Unroll 32 and 16 wide SAD vector implementations by 4	2019-02-04 20:41:40 +02:00
Pauli Oikkonen	a711ce3df5	Inline fixed width vectorized SAD functions	2019-02-04 20:41:40 +02:00
Pauli Oikkonen	6504145cce	Remove 16-pixel wide AVX2 SAD implementation ... At least on Skylake, it's noticeably slower than the very simple version using SSE4.1	2019-02-04 20:41:40 +02:00
Pauli Oikkonen	4cb371184b	Add SSE4.1 strategy for 24px wide SAD and an AVX2 strategy for 16	2019-02-04 20:41:40 +02:00
Pauli Oikkonen	796568d9cc	Add SSE4.1 strategies for SAD on widths 4 and 12 and AVX2 strategies for 32 and 64	2019-02-04 20:41:40 +02:00
Pauli Oikkonen	4d45d828fa	Use constant-width SSE4.1 SAD funcs for AVX2	2019-02-04 20:41:40 +02:00
