Mark Reid	716b396740	avfilter/vf_lut3d: add x86-optimized tetrahedral interpolation 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	3 years ago

Wu Jianhua	7bbad32d5a	libavfilter/x86/vf_gblur: correct the order of loop step The problem was caused by if the width of the processed block minus 1 is a multiple of the aligned number the instruction jle .bscale_scalar would skip the Optimized Loop Step, which will lead to an incorrect sampling when specifying steps more than 1. Move the Optimized Loop Step after .bscale_scalar to ensure the loop step is enabled. Signed-off-by: Wu Jianhua <jianhua.wu@intel.com>	3 years ago

Wu Jianhua	4041c1029b	libavfilter/x86/vf_gblur: add localbuf and ff_horiz_slice_avx2/512() We introduced a ff_horiz_slice_avx2/512() implemented on a new algorithm. In a nutshell, the new algorithm does three things, gathering data from 8/16 rows, blurring data, and scattering data back to the image buffer. Here we used a customized transpose 8x8/16x16 to avoid the huge overhead brought by gather and scatter instructions, which is dependent on the temporary buffer called localbuf added newly.
