Revision 1205 - Directory Listing
Modified Thu Nov 13 23:11:24 2003 UTC (20 years, 5 months ago) by edgomez

MMXed the calculation of SSE for 8x8 16bit blocks. This helps quite
a lot VHQ=4 mode.

My tests show with trellis:chroma_me:
  - ~20% speed improvement for vhq=4.
  - at least 5% when using vhq=1.

Of course this speedup vanishes if more CPU intensive features are
used. CruNcher who used gmc/qpel, noticed "only" a ~5% speed
improvement.

NB: i'm of course talking about overall speed improvement. Such a
small patch for such a big improvement :-)

Modified Mon Nov 3 19:58:16 2003 UTC (20 years, 5 months ago) by edgomez

* Small error fixed by Skal in his dev16 code (missing pshufd).
* Blocks used by DCT tests are now aligned with DECLARE_ALIGNED_MATRIX
  this avoids the well know segfaults when using SSE2 instructions that
  suppose data alignment.
