2016-08-27Move vp9_alt_ref_aq_private.h to vp9_alt_ref_aq.cYury Gitman
+ add a temporary dummy element to ALT_REF_AQ to avoid a warning about an empty struct Change-Id: Ib6e5c39ff62ad96eb4e3686d4882228a42b3843f
2016-08-25Create interface for the ALT_REF_AQ classYury Gitman
Current commit is just an API template for the rest of the code, and I will add inner logic later. Altref frames generate a lot of bitrate and at the same time other frames refer to them a lot, so it makes sense to apply special compensation-based adaptive quantization scheme for altref frames. E.g., for blocks that are good predictors for the future apply rate-control chosen quantizer while for bad predictors apply worse one. Change-Id: Iba3f8ec349470673b7249f6a125f6859336a47c8

This reverts commit be12fefa4b7d224e9f39275a6bb4fab01b8bae3b and commit 057c1c4034ba5b9bf360c5c1f600ebc6d0718c3a. Also, the mismatch between the avx version and the c version has been fixed.

2016-05-27Upgrade fwht4x4_mmx() to fwht4x4_sse2() for vp9 and vp10.Linfeng Zhang
Function level timing test shows about 27% time saving on a Xeon E5-2680 v2 desktop. Rename vp9_dct_sse2.c to vp9_dct_intrin_sse2.c for vp9 and rename dct_sse2.c to dct_intrin_sse2.c for vp10 to avoid duplicate basenames. Actually vp9_fwht4x4_mmx/sse2() and vp10_fwht4x4_mmx/sse2() are identical. TODO: They should be unified later if there is no intention to keep a duplicate.

2015-11-11Add AVX vectorized vp9_diamond_search_sadGeza Lore
This function now has an AVX intrinsics version which is about 80% faster compared to the C implementation. This provides a 2-4% total speed-up for encode, depending on encoding parameters. The function utilizes 3 properties of the cost function lookup table, constructed in 'cal_nmvjointsadcost' and 'cal_nmvsadcosts'. For the joint cost: - mvjointsadcost[1] == mvjointsadcost[2] == mvjointsadcost[3] For the component costs: - For all i: mvsadcost[0][i] == mvsadcost[1][i] (equal per component cost) - For all i: mvsadcost[0][i] == mvsadcost[0][-i] (Cost function is even) These must hold, otherwise the AVX version of the function cannot be used.

This reverts commit f1342a7b070ef61b9fbdf03e899ac2107cfcb6bd. This breaks 32-bit builds: runtime error: load of misaligned address 0xf72fdd48 for type 'const __m128i' (vector of 2 'long long' values), which requires 16 byte alignment + _mm_set1_epi64x is incompatible with some versions of visual studio Change-Id: I6f6fc3c11403344cef78d1c432cdc9147e5c1673

2015-10-21Optimize vp9_highbd_block_error_8bit assembly.Geza Lore
A new version of vp9_highbd_error_8bit is now available which is optimized with AVX assembly. AVX itself does not buy us too much, but the non-destructive 3 operand format encoding of the 128bit SSEn integer instructions helps to eliminate move instructions. The Sandy Bridge micro-architecture cannot eliminate move instructions in the processor front end, so AVX will help on these machines. Further 2 optimizations are applied: 1. The common case of computing block error on 4x4 blocks is optimized as a special case. 2. All arithmetic is speculatively done on 32 bits only. At the end of the loop, the code detects if overflow might have happened and if so, the whole computation is re-executed using higher precision arithmetic. This case however is extremely rare in real use, so we can achieve a large net gain here. The optimizations rely on the fact that the coefficients are in the range [-(2^15-1), 2^15-1], and that the quantized coefficients always have the same sign as the input coefficients (in the worst case they are 0). These are the same assumptions that the old SSE2 assembly code for the non high bitdepth configuration relied on. The unit tests have been updated to take this constraint into consideration when generating test input data. Change-Id: I57d9888a74715e7145a5d9987d67891ef68f39b7
2015-10-08Optimization of 8bit block error for high bitdepthGeza Lore
If high bit depth configuration is enabled, but encoding in profile 0, the code now falls back on optimized SSE2 assembler to compute the block errors, similar to when high bit depth is not enabled. Change-Id: I471d1494e541de61a4008f852dbc0d548856484f
