| 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. |
