* avfilter/vf_lut3d: add x86-optimized tetrahedral interpolationMark Reid2021-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I spotted an interesting pattern that I didn't see before that leads to the implementation being faster. The bit shifting table I was using before is no longer needed, and was able to remove quite a few lines.  I also add use of FMA on the AVX2 version. f32 1920x1080 1 thread with prelut c impl 1434012700 UNITS in lut3d->interp,       1 runs,      0 skips 1434035335 UNITS in lut3d->interp,       2 runs,      0 skips 1423615347 UNITS in lut3d->interp,       4 runs,      0 skips 1426268863 UNITS in lut3d->interp,       8 runs,      0 skips sse2 905484420 UNITS in lut3d->interp,       1 runs,      0 skips 905659010 UNITS in lut3d->interp,       2 runs,      0 skips 915167140 UNITS in lut3d->interp,       4 runs,      0 skips 915834222 UNITS in lut3d->interp,       8 runs,      0 skips avx 574794860 UNITS in lut3d->interp,       1 runs,      0 skips 581035090 UNITS in lut3d->interp,       2 runs,      0 skips 584116720 UNITS in lut3d->interp,       4 runs,      0 skips 581460290 UNITS in lut3d->interp,       8 runs,      0 skips avx2 301698880 UNITS in lut3d->interp,       1 runs,      0 skips 301982880 UNITS in lut3d->interp,       2 runs,      0 skips 306962430 UNITS in lut3d->interp,       4 runs,      0 skips 305472025 UNITS in lut3d->interp,       8 runs,      0 skips gbrap16 1920x1080 1 thread with prelut c impl 1480894840 UNITS in lut3d->interp,       1 runs,      0 skips 1502922990 UNITS in lut3d->interp,       2 runs,      0 skips 1496114307 UNITS in lut3d->interp,       4 runs,      0 skips 1492554551 UNITS in lut3d->interp,       8 runs,      0 skips sse2 980777180 UNITS in lut3d->interp,       1 runs,      0 skips 986121520 UNITS in lut3d->interp,       2 runs,      0 skips 986489840 UNITS in lut3d->interp,       4 runs,      0 skips 998832248 UNITS in lut3d->interp,       8 runs,      0 skips avx 622212360 UNITS in lut3d->interp,       1 runs,      0 skips 622981160 UNITS in lut3d->interp,       2 runs,      0 skips 645396315 UNITS in lut3d->interp,       4 runs,      0 skips 641057075 UNITS in lut3d->interp,       8 runs,      0 skips avx2 321336400 UNITS in lut3d->interp,       1 runs,      0 skips 321268920 UNITS in lut3d->interp,       2 runs,      0 skips 323459895 UNITS in lut3d->interp,       4 runs,      0 skips 324949967 UNITS in lut3d->interp,       8 runs,      0 skips

| | | | | | | | | | | Speed of all modes increased by a factor between 7.4 and 19.8 largely depending on whether bytes are unpacked into words. Modes 2, 3, and 4 have been sped-up by a factor of 43 (thanks quick sort!) All modes are available on x86_64 but only modes 1, 10, 11, 12, 13, 14, 19, 20, 21, and 22 are available on x86 due to the number of SIMD registers used.

* vf_psnr: sse2 optimizations for sum-squared-error.Ronald S. Bultje2015-07-14
| | | | | | | | | | | | The internal line accumulator for 16bit can overflow, so I changed that from int to uint64_t in the C code. The matching assembly looks a little weird but output looks correct. (avx2 should be trivial to add later.)

* | yadif: x86 assembly for 9 to 14-bit samplesJames Darnley2013-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These smaller samples do not need to be unpacked to double words allowing the code to process more pixels every iteration (still 2 in MMX but 6 in SSE2). It also avoids emulating the missing double word instructions on older instruction sets. Like with the previous code for 16-bit samples this has been tested on an Athlon64 and a Core2Quad. Athlon64: 1809275 decicycles in C, 32718 runs, 50 skips 911675 decicycles in mmx, 32727 runs, 41 skips, 2.0x faster 495284 decicycles in sse2, 32747 runs, 21 skips, 3.7x faster Core2Quad: 921363 decicycles in C, 32756 runs, 12 skips 486537 decicycles in mmx, 32764 runs, 4 skips, 1.9x faster 293296 decicycles in sse2, 32759 runs, 9 skips, 3.1x faster 284910 decicycles in ssse3, 32759 runs, 9 skips, 3.2x faster Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
