Ronald S. Bultje	c6fe984f2f	vp9/x86: make STORE_2X2 macro local. Prevents this assembler warning: libavcodec/x86/vp9itxfm.asm:1208: warning: (VP9_IDCT32_1D:309) redefining multi-line macro `STORE_2X2' Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	04a187fb2a	vp9/x86: idct_32x32_add_ssse3 sub-8x8-idct. Runtime of the full 32x32 idct goes from 2446 to 2441 cycles (intra) or from 1425 to 1306 cycles (inter). Overall runtime is not significantly affected.	11 years ago
Ronald S. Bultje	37b001d14d	vp9/x86: idct_32x32_add_ssse3 sub-16x16-idct. Runtime of all IDCTs together goes from 3327 to 2473 cycles (intra, i.e. ~35% faster) or from 2312 to 1448 cycles (inter, i.e. ~60% faster). Total decode time of ped1080p.webm goes from 8.086sec to 7.974sec (1.4% faster).	11 years ago
Ronald S. Bultje	e84d14df10	vp9/x86: idct_32x32_add_ssse3. Sub-IDCTs will follow later. ped1080.webm goes from 9.295s to 8.191s (13.5% faster). The IDCT itself goes from 4372 (intra) or 4337 (inter) to 403 (intra) or 329 (inter) cycles for the DC-only form, 23755 (intra) or 23723 (inter) to 3497 (intra) or 3607 (inter) cycles for the no-DC form, which averages from 23393 (intra) or 16612 (inter) to 3449 (intra) or 2392 (inter) for all 32x32s together, i.e. about ~7x faster (all tests done on ped1080p.webm).	11 years ago
Ronald S. Bultje	0d9375fc90	vp9/x86: 16x16 sub-IDCT for top-left 8x8 subblock (eob <= 38). Sub8x8 speed (w/o dc-only case) goes from ~750 cycles (inter) or ~735 cycles (intra) to ~415 cycles (inter) or ~430 cycles (intra). Average overall 16x16 idct speed goes from ~635 cycles (inter) or ~720 cycles (intra) to ~415 cycles (inter) or ~545 (intra) - all measurements done using ped1080p.webm.	11 years ago
Ronald S. Bultje	8d4c616fc0	vp9/x86: idct_add_16x16_ssse3. Currently only dc-only and full 16x16. Other subforms will follow in the near future. Total decoding time of ped1080p.webm goes from 9.7 to 9.3 seconds. DC-only goes from 957 -> 131 cycles, and the full IDCT goes from ~4050 to ~745 cycles.	11 years ago
Ronald S. Bultje	92436e8ad9	vp9: implement top/left half (4x4) sub-8x8-IDCT. For that specific case (eob>3&&eob<=12), runtime of idct8x8 goes from 668 to 477 cycles. For all idct8x8, runtime goes from 521 to 490 cycles.	11 years ago
Ronald S. Bultje	b2045c44a9	vp9: split pre-load of 11585x2 out of 1d idct macro. This allows us to load it only once, instead of twice, in this function.	11 years ago
Ronald S. Bultje	f9a0d4c6e0	vp9: minor refactorings in idct ssse3 assembly. Make register usage in macros explicit; change mulsub_2w_4x to use 2 instead of 3 temp registers.	11 years ago
Ronald S. Bultje	8729964b99	vp9: split x86 assembly in two files. (And in future, loopfilter or intra pred could be put in their own respective files also.)	11 years ago
Clément Bœsch	616da59542	avcodec/x86/vp9dsp: merge a few SWAP together.	11 years ago
