This means I moved 59 initilisation around and delayed other instruction. 60 Performance measurement did not show that this brought any advantage 61 but in theory it _should_ be faster this way. 62 63 The overall performanve gain to the C based dither was 30%-40%. 64 The MMX routine calculates 256bit=8RGB values in each cycle 65 (4 for row1 & 4 for row2) 66 67 The red/green/blue.. coefficents are taken from the mpeg_play 68 player.
