52 This MMX assembler is my first assembler/MMX program ever.
53 Thus it maybe buggy.
54 Send patches to:
55 mvogt@rhrk.uni-kl.de
56
57 After it worked fine I have "obfuscated" the code a bit to have
58 more parallism in the MMX units. 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. They look nice, but I dont know if you can have
69 better values, to avoid integer rounding errors.
70
71
72 IMPORTANT:
73 ==========
74
75 It is a requirement that the cr/cb/lum are 8 byte aligned and
76 the out are 16byte aligned or you will/may get segfaults
