2013-11-13Simplifies band-getting with a static arrayDeb Mukherjee
Simplifies the code by implementing band mapping with static arrays. A lot of the code complexity introduced in a previous patch disappears. Change-Id: Ia3fac36e594fb5ad2d55ae141c58bba4c55c2d28

2013-11-12Removes conditional statements from band gettingDeb Mukherjee
Implements scan order to band map with arrays in both the encoder and decoder to remove conditional statements. Encoding seems to be about 1% faster at speed 0, tested on football. Decoding seems to be about 0.5-1% faster on a set of 25 videos. Change-Id: Idb233ca0b9e0efd790e30880642e8717e1c5c8dd

2013-10-11Replacing {VP9_COEF, MODE}_UPDATE_PROB with DIFF_UPDATE_PROB.Dmitry Kovalev
Values of MODE_UPDATE_PROB and VP9_COEF_UPDATE_PROB are equal, so replacing them with one constant. Inlining appropriate arguments for functions: vp9_cond_prob_diff_update (encoder) vp9_diff_update_prob (decoder) Change-Id: I1255a1cb477743b799b3bfbbcd8de6b32b067338
2013-10-10Removing vp9_tree_p typedef.Dmitry Kovalev

2013-10-07Moving all scan/iscan code into separate vp9_scan.{h, c} files.Dmitry Kovalev
Now we have entropy code separate from scan/iscan code. The next step in future is to move iscan code from common part to the encoder. Change-Id: Id9732f7d80aec00af35c1d58d1137c4c96c91451

2013-07-25General cleanups.Dmitry Kovalev
Removing unused constants, macros, and function declarations. Using ROUND_POWER_OF_TWO macro, vp9_zero, vp9_copy where possible. Moving #include from *.h to *.c. Merging for loops for motion vectors. Change-Id: Ic3bf841764a2bb177128bb3a6d7aa8f68229cd13
2013-07-22More optimizations for cost_coeffs().Ronald S. Bultje
4x4: 163 -> 123 cycles (33% faster) 8x8: 491 -> 399 cycles (23% faster) 16x16: 1889 -> 1763 cycles (7% faster) 32x32: 8311 -> 8180 cycles (1.6% faster) Overall encoding time of first 50 frames of bus (speed 0) @ 1500kbps goes from 1min4.33 to 1min3.00, i.e. 2.11% faster. Change-Id: Ib52d1dbb5649b14de769d3e7a74af67440b5284f
2013-07-15Removing and moving around constant definitions.Dmitry Kovalev
Removing unused and duplicated constants, moving them from *.h to *.c if possible. Change-Id: Ief4d6b984a3ca2e9b38504f0d855ed072cf7133f
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
2013-06-24Move vp9_full_to_model_counts to encoderJohn Koleszar
This function is not called from the decoder, so it doesn't need to be in common/. Change-Id: I6977dd462a25b4ff39c9c7e1b0b5b16aa58ee733
2013-06-21Remove unused vp9_model_to_full_probs_sb()John Koleszar
This function never referenced. Change-Id: I1c42cd355bfa88e17d169f7335a44be682af58cc
