      Removing redundant parenthesis and curly braces. Combining declarations
      with initializations. Adding useful intermediate variables instead of
      recalculating expressions every time.

      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

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

      Replace scatter scan 32x32 with HW friendly scan. · 5700b4ea
      Sami Pietila authored
      The first 240 coeff positions (15 top-left blocks) are scanned in the
      same order as in scatter scan, after that the coeffs are scanned in
      "block bands", each band at a time, all coeffs in one band before
      moving on to the next band. This brings down the amount of 4x4 coeff
      blocks that need to be buffered while scanning, from 15 blocks to 8 blocks.

      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.

      Residual coding to cache energy class of tokens. · 88a4d4c5
      Sami Pietila authored
      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.

      Using 128 entry look up table for coef models · de4d682c
      Deb Mukherjee authored
      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.
