/ dct36_3dnow.s - 3DNow! optimized dct36()
|
||
|
|
/
|
||
|
|
/ This code based 'dct36_3dnow.s' by Syuuhei Kashiyama
|
||
|
|
/ <squash@mb.kcom.ne.jp>,only two types of changes have been made:
|
||
|
|
/
|
||
|
|
/ - remove PREFETCH instruction for speedup
|
||
|
|
/ - change function name for support 3DNow! automatic detect
|
||
|
|
/
|
||
|
|
/ You can find Kashiyama's original 3dnow! support patch
