      Accelerated transform in high bit depth · 406030d1
      Julia Robson authored
      When configured with high bitdepth enabled, the 8bit transform
      stopped using optimised code. This made 8bit content decode slowly.

      Factor inverse transform functions into vpx_dsp · e8b133c7
      Jingning Han authored
      This commit moves the module inverse transform functions from vp9
      to vpx_dsp folder. The hybrid transform wrapper functions stay in
      the vp9 folder, since it involves codec-specific data structures.

      vp9_idct_intrin_*: RECON_AND_STORE: remove dest offset · 778845da
      James Zern authored
      offsetting by a variable stride prevents instruction reordering,
      resulting in poor assembly.
      additionally reroll 16x16/32x32 loops to reduce register spill with this
      new format

      Enable SSSE3 inverse 2D-DCT with 10 non-zero coeffs · 6d21cbd2
      Jingning Han authored
      This commit enables SSSE3 implementation of the inverse 2D-DCT
      with only first 10 coefficients non-zero. It reduces the runtime
      of SSE2 version from 745 cycles to 538 cycles, i.e., 27% speed-up.

      Inverse 16x16 2D-DCT SSSE3 implementation · 48b08913
      Jingning Han authored
      This commit enables the SSSE3 implementation of full inverse 16x16
      2D-DCT. The unit runtime goes down from 1642 cycles to 1519 cycles,
      about 7% speed-up.
