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.

Pauli Oikkonen df2e6c54fd 4-unroll hor_sad_sse41_arbitrary
This may not increase perf though because it's so rarely used
function, so keeping icache footprint may be more essential...

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 57db234d95 Move 32-wide SSE4.1 hor_sad to picture-sse41.c
It's not used by picture-avx2.c that also includes the header, so
it should not be in the header

Pauli Oikkonen 768203a2de First version of arbitrary-width SSE4.1 hor_sad 2019-02-04 20:41:40 +02:00
Pauli Oikkonen ccf683b9b6 Start work on left and right border aware hor_sad
Comes with 4, 8, 16 and 32 pixel wide implementations now, at some point
investigate if this can start to thrash icache
2019-02-04 20:41:40 +02:00
Pauli Oikkonen 760bd0397d Pad the image buffer by 64 bytes from both ends
This will be necessary for an efficient and straightforward
implementation of hor_sad for blocks over 16 pixels wide, because they
cannot use the shuffle trick because inter-lane shuffling is so hard to
do

Pauli Oikkonen 007fb7ae19 Un-break tests
Pass the NULL optimized function pointer from the test function, it
should still forward execution to width-specific SAD implementations
2019-02-04 20:41:40 +02:00
Pauli Oikkonen 91380729b1 Add generic get_optimized_sad implementation
NOTE: To force generic SAD implementation on devices supporting
vectorized variants, you now have to override both get_optimized_sad
and reg_sad to generic (only overriding get_optimized_sad on AVX2
hardware would just run all SAD blocks through reg_sad_avx2). Let's
see if there's a more sensible way to do it, but it's not trivial.
