      Rework idct calling structure. · 93c32a55
      Fritz Koenig authored
      Moving the eob structure allows for a non-struct based
      function to handle decoding an entire mb of
      idct/dequant/recon data.  This allows for SIMD functions
      to idct/dequant/recon multiple blocks at once.
      
      SSE2 implementation gives 3% gain on Atom.

      framework for assembly version of the detokenizer · 9602799c
      Johann authored
      adds a compile time option: --enable-arm-asm-detok which pulls in
      vp8/decoder/arm/detokenize.asm
      
      currently about break even speed wise, but changes are pending to
      the fill code (branch and load 3 bytes versus conditionally always
      load one) and the error handling. Currently it doesn't handle zero
      runs or overrunning the buffer.
      
      this is really just so i don't have to rebase my changes all the
      time to run benchmarks - now just need to replace one file!

      update arm idct functions · 56f5a9a0
      Johann authored
      Jeff Muizelaar posted some changes to the idct/reconstruction c code.
      This is the equivalent update for the arm assembly.
      
      This shows a good boost on v6, and a minor boost on neon.
      Here are some numbers for highway in qcif, 2641 frames:
      HEAD neon: ~161 fps
      new neon:  ~162 fps
      HEAD v6:   ~102 fps
      new v6:    ~106 fps
      
      The following functions have been updated for armv6 and neon:
      vp8_dc_only_idct_add
      vp8_dequant_idct_add
      vp8_dequant_dc_idct_add
      
      Conflicts:
      
      	vp8/decoder/arm/armv6/dequantdcidct_v6.asm
      	vp8/decoder/arm/armv6/dequantidct_v6.asm
      
      Resolved by removing these files. When I rewrote the functions, I also
      moved the files to dequant_dc_idct_v6.asm/dequant_idct_v6.asm

      Combine idct and reconstruction steps · b2fa74ac
      Jeff Muizelaar authored
      This moves the prediction step before the idct and combines the idct and
      reconstruction steps into a single step. Combining them seems to give an
      overall decoder performance improvement of about 1%.

      Remove CONFIG_NEW_TOKENS files. · 08eed049
      Fritz Koenig authored
      These files were out of date and no longer maintained.
      Token decoding has implemented the no-crash code which
      is incompatible with this arm assembly code.

      cosmetics: trim trailing whitespace · 94c52e4d
      John Koleszar authored
      When the license headers were updated, they accidentally contained
      trailing whitespace, so unfortunately we have to touch all the files
      again.

      Change bitreader to use a larger window. · c17b62e1
      Timothy B. Terriberry authored
      Change bitreading functions to use a larger window which is refilled less
       often.
      
      This makes it cheap enough to do bounds checking each time the window is
       refilled, which avoids the need to copy the input into a large circular
       buffer.
      This uses less memory and speeds up the total decode time by 1.6% on an ARM11,
       2.8% on a Cortex A8, and 2.2% on x86-32, but less than 1% on x86-64.
      
      Inlining vp8dx_bool_decoder_fill() has a big penalty on x86-32, as does moving
       the refill loop to the front of vp8dx_decode_bool().
      However, having the refill loop between computation of the split values and
       the branch in vp8_decode_mb_tokens() is a big win on ARM (presumably due to
       memory latency and code size: refilling after normalization duplicates the
       code in the DECODE_AND_BRANCH_IF_ZERO and DECODE_AND_LOOP_IF_ZERO cases.
      Unfortunately, refilling at the end of vp8dx_bool_decoder_fill() and at the
       beginning of each decode step in vp8_decode_mb_tokens() means the latter
       requires an extra refill at the end.
      Platform-specific versions could avoid the problem, but would require most of
       detokenize.c to be duplicated.
