Clément Bœsch	62d31307c1	avcodec/x86/vp9lpf: add a comment above a bunch of SWAP.	11 years ago
Clément Bœsch	f0d368d758	avcodec/x86/vp9lpf: merge a few movs with other instructions.	11 years ago
Clément Bœsch	010732b73a	vp9/x86: simplify FILTER_INIT. In the 2 FILTER_INIT usages, the source is already preloaded so that extra complexity taken from FILTER_UPDATE is not necessary. Also add forgotten "mask" argument in FILTER_{INIT,UPDATE} comments.	11 years ago
Clément Bœsch	b8d002dc95	vp9/x86: clarify mixed splatb.	11 years ago
Clément Bœsch	669d4f9053	x86/vp9lpf: simplify 2nd transpose in 44/48/88/84. For non-avx optims, this saves 8 movs. before: 1785 decicycles in ff_vp9_loop_filter_h_44_16_ssse3, 524129 runs, 159 skips 3327 decicycles in ff_vp9_loop_filter_h_48_16_ssse3, 262116 runs, 28 skips 2712 decicycles in ff_vp9_loop_filter_h_88_16_ssse3, 4193729 runs, 575 skips 3237 decicycles in ff_vp9_loop_filter_h_84_16_ssse3, 524061 runs, 227 skips after: 1768 decicycles in ff_vp9_loop_filter_h_44_16_ssse3, 524062 runs, 226 skips 3310 decicycles in ff_vp9_loop_filter_h_48_16_ssse3, 262107 runs, 37 skips 2719 decicycles in ff_vp9_loop_filter_h_88_16_ssse3, 4193954 runs, 350 skips 3184 decicycles in ff_vp9_loop_filter_h_84_16_ssse3, 524236 runs, 52 skips	11 years ago
Clément Bœsch	d92a725329	x86/vp9lpf: remove 8 SWAPs in 84/48 transpose.	11 years ago
Clément Bœsch	97dde561de	x86/vp9lpf: remove braindead double pxor.	11 years ago
Clément Bœsch	9a3b05b0a9	x86/vp9lpf: save a few mov in flat8in/hev masks calc.	11 years ago
Clément Bœsch	91d85bb167	x86/vp9lpf: add ff_vp9_loop_filter_[vh]_44_16_{sse2,ssse3,avx}.	11 years ago
Clément Bœsch	c5dd73b890	x86/vp9lpf: add ff_vp9_loop_filter_h_{48,84}_16_{sse2,ssse3,avx}(). 5.40s → 5.30s overall decode time with -threads 1 on ped1080p.webm (i7 920, ssse3)	11 years ago
James Almer	644c32ea4b	x86/vp9lpf: add ff_vp9_loop_filter_[vh]_88_16_sse2() Similar gains as the ssse3 version once again Signed-off-by: James Almer <jamrial@gmail.com>	11 years ago
Clément Bœsch	222c46c531	x86/vp9lpf: add ff_vp9_loop_filter_[vh]_88_16_{ssse3,avx}. 9680 decicycles in loop_filter_v_88_16_c, 4193765 runs, 539 skips 9233 decicycles in loop_filter_h_88_16_c, 4193751 runs, 553 skips 1929 decicycles in ff_vp9_loop_filter_v_88_16_ssse3, 4194118 runs, 186 skips 2738 decicycles in ff_vp9_loop_filter_h_88_16_ssse3, 4193861 runs, 443 skips 5.978 → 5.417 overall decode time on ped1080p.webm (-threads 1) Adding SSE2 support should be relatively trivial (just a matter of changing the pshufb [mask_mix] with something else), patch welcome.	11 years ago
Clément Bœsch	822385d775	x86/vp9lpf: add a preload system in FILTER_UPDATE. Allow some macro refactoring in filter14().	11 years ago
Clément Bœsch	315b4775ad	x86/vp9lpf: refactor v/h using common macros for P7 to Q7.	11 years ago
Clément Bœsch	5d144086cc	x86/vp9lpf: faster P7..Q7 accesses. Introduce 2 additional registers for stride3 and mstride3 to allow direct accesses (lea drops). 3931 → 3827 decicycles in ff_vp9_loop_filter_v_16_16_ssse3 Also uses defines to clarify the code.	11 years ago
James Almer	d2a7314f1e	vp9/x86: add ff_vp9_loop_filter_[vh]_16_16_sse2(). Similar gains in performance as the SSSE3 version Signed-off-by: James Almer <jamrial@gmail.com>	11 years ago
