* dct36_k7.c - 3DNowEx(DSP)! optimized dct36()
|
|
*
|
|
* This code based 'dct36_3dnow.s' by Syuuhei Kashiyama
|
|
* <squash@mb.kcom.ne.jp>, only two types of changes have been made:
|
|
*
|
|
* - added new opcode PSWAPD
|
|
* - removed PREFETCH instruction for speedup
|
|
* - changed function name for support 3DNowEx! automatic detection
|
|
*
|
|
* note: because K7 processors are an aggresive out-of-order three-way
|
|
* superscalar ones instruction order is not significand for them.
|
|
*
|
|
* You can find Kashiyama's original 3dnow! support patch
