* 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

|
|
* 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.
