      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.

      Refactored idct routines and headers · 3a8c43a4
      Peter de Rivaz authored
      This change is made in preparation for a
      subsequent patch which adds acceleration
      for the highbitdepth transform functions.
      
      The highbitdepth transform functions attempt
      to use 16/32bit sse instructions where possible,
      but fallback to using the C implementations if
      potential overflow is detected.  For this reason
      the dct routines are made global so they can be
      called from the acceleration functions in the
      subsequent patch.

      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.

      Change eob threshold for partial inverse 8x8 2D-DCT to 12 · 41a350a8
      Jingning Han authored
      The scanning order has the first 12 coefficients of the 8x8 2D-DCT
      sitting in the top left 4x4 block. Hence the partial inverse 8x8
      2D-DCT allows to handle cases with eob below 12.
      
      The overall runtime of the inverse 8x8 2D-DCT unit is reduced from
      166 cycles (using SSE2) to 150 cycles (using SSSE3).

      version of vp9_short_idct32x32_1_add will be added in the next patch set,
      right now it is only C implementation. Now we have all idct functions
      implemented in a consistent manner.
