| 71 This MMX assembler is my first assembler/MMX program ever. | |
| 72 Thus it maybe buggy. | |
| 73 Send patches to: | |
| 74 mvogt@rhrk.uni-kl.de | |
| 75 | |
| 76 After it worked fine I have "obfuscated" the code a bit to have | |
| 77 more parallism in the MMX units. This means I moved | |
| 78 initilisation around and delayed other instruction. | |
| 79 Performance measurement did not show that this brought any advantage | |
| 80 but in theory it _should_ be faster this way. | |
| 81 | |
| 82 The overall performanve gain to the C based dither was 30%-40%. | |
| 83 The MMX routine calculates 256bit=8RGB values in each cycle | |
| 84 (4 for row1 & 4 for row2) | |
| 85 | |
| 86 The red/green/blue.. coefficents are taken from the mpeg_play | |
| 87 player. They look nice, but I dont know if you can have | |
| 88 better values, to avoid integer rounding errors. | |
| 89 | |
| 90 | |
| 91 IMPORTANT: | |
| 92 ========== | |
| 93 | |
| 94 It is a requirement that the cr/cb/lum are 8 byte aligned and | |
| 95 the out are 16byte aligned or you will/may get segfaults | |
