  • reimplemented remaing avg_ pixel functions
  • modified PAVGB mmx macro to select mmx register with FE constant

Originally committed as revision 657 to svn://svn.ffmpeg.org/ffmpeg/trunk

fca0f0e5 05/30/2002 03:14 PM Zdenek Kabelac
  • removed MANGLE from macros for setting constants
  • using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access
    as its always faster
  • PAVGB_MMX macro is using now mm6 -> mm7 is unmodified
  • replaced original pixels_xy2_mmx with new faster and equal implementation...
6aa6ea8e 05/29/2002 07:57 PM Zdenek Kabelac
  • reenabled original xy2 put routine - rounding error is really bad with
    the new code
  • added PAVGP macros for parallel processing to safe few more cycles on
    celerons

Originally committed as revision 625 to svn://svn.ffmpeg.org/ffmpeg/trunk

91abb473 05/29/2002 05:16 PM Zdenek Kabelac
  • code with new PAVGB for MMX only CPU splited into separate file
    and being compiled in the same way as _avg.h
  • PAVG_MMX macros accept also output parameter
  • implemented faster put_pixels_xy2, but it has slightly smaller precission.
    But there is not visible difference in the image quality - might be eventualy...

  • some modifications to allow gcc to compile same code for -fPIC
    - introduced MOVQ_WONE, MOVQ_WTWO
  • unrolled put_pixels_clamped_mmx
  • added .baling where the jump address would be compiled on odd address
  • added some testing code to disable all these routines (for time measurement)...
