-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 code.
-
-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 where you specify 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
-
-March 27,2004
-PERFORMANCE ANALYSIS
-
-The C version uses 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 10 clocks 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 issue, 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.
