14 * dct36_3dnow.c - 3DNow! optimized dct36()
|
|
|
15 *
|
|
|
16 * This code based 'dct36_3dnow.s' by Syuuhei Kashiyama
|
|
|
17 * <squash@mb.kcom.ne.jp>, 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 <kim@hannah.ipc.miyakyo-u.ac.jp> - until 31.Mar.1999
|
|
|
27 * <kim@comtec.co.jp> - after 1.Apr.1999
|
|
|
