      Simplifies band-getting with a static array · cfcd5c4f
      Deb Mukherjee authored
      Simplifies the code by implementing band mapping with static arrays.
      A lot of the code complexity introduced in a previous patch
      disappears.

      Replacing {VP9_COEF, MODE}_UPDATE_PROB with DIFF_UPDATE_PROB. · 4a0f9478
      Dmitry Kovalev authored
      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)

      Removing vp9_tree_p typedef. · 98400c1b
      Dmitry Kovalev authored
      It is used only two times and it is more clear to use real type instead
      of typedef.

      Make get_coef_context() branchless. · 26b6318d
      Ronald S. Bultje authored
      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.

      x86-64 only, it needs some minor modifications to be 32bit compatible,
      because it uses 15 xmm registers, whereas 32bit only has 8.

      Balancing coef-tree to reduce bool decodes · b8b3f1a4
      Deb Mukherjee authored
      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%
