altivec yuv->rgb converter
orginal patch by (Marc Hoffman <mmh at pleasantst dot com>) critical fixes by (Reza Jelveh <reza.jelveh at tu-harburg dot de>) known bugs/issues, which should be fixed ASAP by someone who has a ppc: 0..255 vs. 16..235 unneeded recalculation of tables general cleaup, like removing double initalizing of variables Originally committed as revision 12699 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc

Altivec Acceleration for Color Space Conversion revision 0.2
|
||||
|
||||
convert I420 YV12 to RGB in various formats,
|
||||
it rejects images that are not in 420 formats
|
||||
it rejects images that don't have widths of multiples of 16
|
||||
it rejects images that don't have heights of multiples of 2
|
||||
reject defers to C simulation codes.
|
||||
|
||||
lots of optimizations to be done here
|
||||
|
||||
1. need to fix saturation code, I just couldn't get it to fly with packs and adds.
|
||||
so we currently use max min to clip
|
||||
|
||||
2. the inefficient use of chroma loading needs a bit of brushing up
|
||||
|
||||
3. analysis of pipeline stalls needs to be done, use shark to identify pipeline stalls
|
||||
|
||||
|
||||
MODIFIED to calculate coeffs from currently selected color space.
|
||||
MODIFIED core to be a macro which you spec the output format.
|
||||
ADDED UYVY conversion which is never called due to some thing in SWSCALE.
|
||||
CORRECTED algorithim selection to be strict on input formats.
|
||||
ADDED runtime detection of altivec.
|
||||
|
||||
ADDED altivec_yuv2packedX vertical scl + RGB converter

PERFORMANCE ANALYSIS
|
||||
|
||||
The C version use 25% of the processor or ~250Mips for D1 video rawvideo used as test
|
||||
The ALTIVEC version uses 10% of the processor or ~100Mips for D1 video same sequence
|
||||
|
||||
720*480*30 ~10MPS
|
||||
|
||||
so we have roughly 10clocks per pixel this is too high something has to be wrong.
|
||||
|
||||
OPTIMIZED clip codes to utilize vec_max and vec_packs removing the need for vec_min.
|
||||
|
||||
OPTIMIZED DST OUTPUT cache/dma controls. we are pretty much
|
||||
guaranteed to have the input video frame it was just decompressed so
|
||||
it probably resides in L1 caches. However we are creating the
|
||||
output video stream this needs to use the DSTST instruction to
|
||||
optimize for the cache. We couple this with the fact that we are
|
||||
not going to be visiting the input buffer again so we mark it Least
|
||||
Recently Used. This shaves 25% of the processor cycles off.
|
||||
|
||||
Now MEMCPY is the largest mips consumer in the system, probably due
|
||||
to the inefficient X11 stuff.
|
||||
|
||||
GL libraries seem to be very slow on this machine 1.33Ghz PB running
|
||||
Jaguar, this is not the case for my 1Ghz PB. I thought it might be
|
||||
a versioning issues, however i have libGL.1.2.dylib for both
|
||||
machines. ((We need to figure this out now))
|
||||
|
||||
GL2 libraries work now with patch for RGB32
|
||||
|
||||
NOTE quartz vo driver ARGB32_to_RGB24 consumes 30% of the processor
|
||||
|
||||
Integrated luma prescaling adjustment for saturation/contrast/brightness adjustment.
