2013-07-29Remove a redundant branching in tokenize_bJingning Han
The tokenize_b function is only called when output flag is on. Hence removing the conditional branch on it therein. Change-Id: Ib709f47f23f39ca05a695faf86fa3377f11f2dd0
2013-07-29Tune tokenization/detokenization flow for speed-upJingning Han

2013-07-24Adding condition inside get_tx_type_{4x4, 8x8, 16x16}.Dmitry Kovalev
Adding plane type check condition because it was always used outside of get_tx_type_{4x4, 8x8, 16x16}. Change-Id: I02f0bbfee8063474865bd903eb25b54d26e07230
2013-07-23Moving counts from FRAME_CONTEXT to new struct FRAME_COUNTS.Dmitry Kovalev
Counts are separate from frame context. We have several frame contexts but need only one copy of all counts. Change-Id: I5279b0321cb450bbea7049adaa9275306a7cef7d

2013-07-01Make get_coef_context() branchless.Ronald S. Bultje
This should significantly speedup cost_coeffs(). Basically what the patch does is to make the neighbour arrays padded by one item to prevent an eob check in get_coef_context(), then it populates each col/row scan and left/top edge coefficient with two times the same neighbour - this prevents a single/double context branch in get_coef_context(). Lastly, it populates neighbour arrays in pixel order (rather than scan order), so we don't have to dereference the scantable to get the correct neighbours. Total encoding time of first 50 frames of bus (speed 0) at 1500kbps goes from 2min10.1 to 2min5.3, i.e. a 2.6% overall speed increase. Change-Id: I42bcd2210fd7bec03767ef0e2945a665b851df56
2013-07-01Quantize (64-bit only, for now) SSSE3 SIMD.Ronald S. Bultje
Total encoding time for first 50 frames of bus (speed 0) @ 1500kbps goes 2min34.8 to 2min14.4, i.e. a 10.4% overall speedup. The code is x86-64 only, it needs some minor modifications to be 32bit compatible, because it uses 15 xmm registers, whereas 32bit only has 8. Change-Id: I2df53770c2e850813ffa713e1a91b45b0082b904
2013-06-28Inline vp9_get_coef_context() (and remove vp9_ prefix).Ronald S. Bultje
Makes cost_coeffs() a lot faster: 4x4: 236 -> 181 cycles 8x8: 888 -> 588 cycles 16x16: 3550 -> 2483 cycles 32x32: 17392 -> 12010 cycles Total encode time of first 50 frames of bus (speed 0) @ 1500kbps goes from 2min51.6 to 2min43.9, i.e. 4.7% overall speedup. Change-Id: I16b8d595946393c8dc661599550b3f37f5718896
2013-06-25Removing unused code.Dmitry Kovalev

2013-06-07Cleans up mbskip encodingDeb Mukherjee
Refactors mbskip coding to be compatible with coding of the rest of the symbols. Adds forward/backward adaptation and removes a lot of the legacy code. Results: fast50: +1.6% derfraw300: +0.317% Change-Id: I395a2976d15af044d3b8ded5acfa45f6f065f980
2013-06-06Change ref frame coding.Ronald S. Bultje
Code intra/inter, then comp/single, then the ref frame selection. Use contextualization for all steps. Don't code two past frames in comp pred mode. Change-Id: I4639a78cd5cccb283023265dbcc07898c3e7cf95
2013-06-06don't tokenize & encode tokens for blocks in UMVJim Bankoski
This avoids encoding tokens for blocks that are entirely in the UMV border. This changes the bitstream. Change-Id: I32b4df46ac8a990d0c37cee92fd34f8ddd4fb6c9
2013-05-31Merge all various transform size data trackers into single variables.Ronald S. Bultje

2013-05-29Balancing coef-tree to reduce bool decodesDeb Mukherjee
This patch changes the coefficient tree to move the EOB to below the ZERO node in order to save number of bool decodes. The advantages of moving EOB one step down as opposed to two steps down in the other parallel patch are: 1. The coef modeling based on the One-node becomes independent of the tree structure above it, and 2. Fewer conext/counter increases are needed. The drawback is that the potential savings in bool decodes will be less, but assuming that 0s are much more predominant than 1's the potential savings is still likely to be substantial. Results on derf300: -0.237% Change-Id: Ie784be13dc98291306b338e8228703a4c2ea2242
2013-05-29Residual coding to cache energy class of tokens.Sami Pietila
Proposal for tuning the residual coding by changing how the context from previous tokens is calculated. Storing the energy class of previous tokens instead of the token itself eases the critical path of HW implementations. Change-Id: I6d71d856b84518f6c88de771ddd818436f794bab
2013-05-23Merge Scatter Scan experiment.Paul Wilkins
Removal from under configure flag. A bit renaming Change-Id: I2213229dfe852001dfec16b149f47c52ce88f3aa
2013-05-23Merge 4x4 block level partition into codebaseJingning Han
Move 4x4/4x8/8x4 partition coding out of experimental list. This commit fixed the unit test failure issues. It also resolved the merge conflicts between 4x4 block level partition and iterative motion search for comp_inter_inter. Change-Id: I898671f0631f5ddc4f5cc68d4c62ead7de9c5a58
2013-05-22Using 128 entry look up table for coef modelsDeb Mukherjee
Reverts to using 128 bit LUT for the coef models rather than 48 to ease hardware implementation. Also incorporates some cleanups including removing various hooks to support different lookup tables based on block_type and ref_type. Change-Id: I54100c120cca07a2ebd3a7776bc4630fa6a153f6
2013-05-21Merging the model coef prob experimentDeb Mukherjee
Merges the experiment. Change-Id: I4eb19af6de6df6aa3a96a2e82f231d47ed9b3ae9
2013-05-20Updating the model coef experimentDeb Mukherjee
Cleans up the experiment. Actually uses reduced counts for backward updates, and reduced number of probabilities in the context. No change in bitstream when the experiment is on. Between expt on and off: derfraw300 is down only -0.062% (which is better than when expts were run previously). Change-Id: I55285a049a0c22810bdb42914212ab5a4f8521b5
2013-05-14Enable recursive partition down to 4x4Jingning Han
This commit allows the rate-distortion optimization recursion at encoder to go down to 4x4 block size. It deprecates the use of I4X4_PRED and SPLITMV syntax elements from bit-stream writing/reading. Will remove the unused probability models in the next patch. The partition type search and bit-stream are now capable of supporting the rectangular partition of 8x8 block, i.e., 8x4 and 4x8. Need to revise the rate-distortion parts to get these two partition tested in the rd loop. Change-Id: I0dfe3b90a1507ad6138db10cc58e6e237a06a9d6
2013-05-13Change to band calculation.Paul Wilkins
Change band calculation back to simpler model based on the order in which coefficients are coded in scan order not the absolute coefficient positions. With the scatter scan experiment enabled the results were appear broadly neutral on derf (-0.028) but up a little on std-hd +0.134). Without the scatterscan experiment on the results were up derf as well. Change-Id: Ie9ef03ce42a6b24b849a4bebe950d4a5dffa6791

2013-04-29Immigrate tokenize_mb into tokenize_sbJingning Han
Unify the tokenize_ function and enable configurable block size for superblock 8x8. We are immigrating the functionalities of macroblock handles into superblock ones, and eventually will remove encode_mb and decode_mb. To be continued on detokenize_ module.

2013-04-29Change above/left_context to use an 8x8 basis.Ronald S. Bultje
Output changes slightly because of a minor bug in (at least) the sb32x16 block2above tx16x16 tables that previously existed in vp9_blockd.c. Change-Id: I624af28ac200a8322d64454cf05c79e9502968cc
2013-04-25Use b_width/height_log2 instead of mb_ where appropriate.Ronald S. Bultje

2013-04-22End of orientation zero group experimentDeb Mukherjee
Adds an experiment that codes an end-of-orientation symbol for every eligible zero encountered in scan order. This cleans out various other sub-experiments that were part of the origiinal patch, which will be later included if found useful. Results are slightly positive on all sets (0.1 - 0.2% range).
