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.
