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