      Incorporate WRAPLOW macro into non-highbitdepth tx · d50716fa
      Deb Mukherjee authored
      Incorporates the WRAPLOW macro into the non-highbitdepth transforms
      to aid hardware verification between a software C model and an
      intended hardware implementation though the use of the configure
      options: --enable-experimental --enable-emulate-hardware.
      Note that to avoid further discrepancies between the sse/sse2
      implementations of the transforms and the C implementation, when the
      emulate hardware option is invoked, we also disable sse/sse2/etc.
      Also incudes some minor cleanups/renaming etc.

      Adds high bitdepth transform functions and tests · 10783d4f
      Deb Mukherjee authored
      Adds various high bitdepth transform functions and tests.
      Much of the changes are related to using typedefs tran_low_t
      and tran_high_t for the final transform cofficients and intermediate
      stages of the transform computation respectively rather than fixed
      types int16_t/int. When vp9_highbitdepth configure flag is off,
      these map tp int16_t/int32_t, but when the flag is on, they map
      to int32_t/int64_t to make space for needed extra precision.

      SSE2 8-tap sub-pixel filter optimization · 3fb728c7
      Yunqing Wang authored
      To ensure fast encoding/decoding on devices without ssse3 support,
      SSE2 optimization of sub-pixel filters was done. Test using 1080p
      clip showed the decoder speeds were ~70fps with ssse3 filters, ~60fps
      with sse2 filters, and ~15fps with c filters.

      Fix intermediate height in convolve_c · e326cecf
      Tero Rintaluoma authored
      - Intermediate height was not correct i.e. when block size is 4 and
        y_step_q4 is 6. In this case intermediate height was
        (4*6) >> 4 = 1 and vertical interpolation needs two source pixels
        plus 7 extra pixels for taps.
      - Also if the current output block is 16x16 and we are using 4x upscaling
        we need only 12 rows after horizontal filtering instead of 16.
        Patch Set 2: Intermediate_height updated after CL 66723

      Fix bug in convolution functions (filter selection) · 3f108313
      Adrian Grange authored
      (In response to Issue 604:
      There were bugs in the convolution code for two cases:
      1. Where the filter table was assumed to be aligned to a
         256 byte boundary. The offset of the pixel in the
         source buffer was computed incorrectly.
      2. Where no such alignment assumption was made. An
         incorrect address for the filter table base was used.
      To fix both problems, I now assume that the filter table is
      256-byte aligned and modify the pixel offset calculation to
      A later patch should remove the restriction that the filter
      table is aligned to a 256-byte boundary.
      There was also a bug in the ConvolveTest unit test
      (Bug & initial fix suggestion submitted by Tero Rintaluoma
      and Sami Pietilä).
