64 This MMX assembler is my first assembler/MMX program ever.
|
|
|
65 Thus it maybe buggy.
|
|
|
66 Send patches to:
|
|
|
67 mvogt@rhrk.uni-kl.de
|
|
|
68
|
|
|
69 After it worked fine I have "obfuscated" the code a bit to have
|
|
|
70 more parallism in the MMX units. This means I moved
|
|
|
71 initilisation around and delayed other instruction.
|
|
|
72 Performance measurement did not show that this brought any advantage
|
|
|
73 but in theory it _should_ be faster this way.
|
|
|
74
|
|
|
75 The overall performanve gain to the C based dither was 30%-40%.
|
|
|
76 The MMX routine calculates 256bit=8RGB values in each cycle
|
|
|
77 (4 for row1 & 4 for row2)
|
|
|
78
|
|
|
79 The red/green/blue.. coefficents are taken from the mpeg_play
|
|
|
80 player. They look nice, but I dont know if you can have
|
|
|
81 better values, to avoid integer rounding errors.
|
|
|
82
|
|
|
83
|
|
|
84 IMPORTANT:
|
|
|
85 ==========
|
|
|
86
|
|
|
87 It is a requirement that the cr/cb/lum are 8 byte aligned and
|
|
|
88 the out are 16byte aligned or you will/may get segfaults
