* dct36_3dnow.c - 3DNow! optimized dct36() |
|
|
15 |
* |
|
|
16 |
* This code based 'dct36_3dnow.s' by Syuuhei Kashiyama |
|
|
17 |
* , only two types of changes have been made: |
|
|
18 |
* |
|
|
19 |
* - removed PREFETCH instruction for speedup |
|
|
20 |
* - changed function name for support 3DNow! automatic detection |
|
|
21 |
* |
|
|
22 |
* You can find Kashiyama's original 3dnow! support patch |
|
|
23 |
* (for mpg123-0.59o) at |
|
|
24 |
* http://user.ecc.u-tokyo.ac.jp/~g810370/linux-simd/ (Japanese). |
|
|
25 |
* |
|
|
26 |
* by KIMURA Takuhiro - until 31.Mar.1999 |
|
|
27 |
* - after 1.Apr.1999 |
