* dct36_3dnow.c - 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:
|
|
*
|
|
* - removed PREFETCH instruction for speedup
|
|
* - changed function name for support 3DNow! automatic detection
|
|
*
|
|
* You can find Kashiyama's original 3dnow! support patch
|
|
* (for mpg123-0.59o) at
|
|
* http://user.ecc.u-tokyo.ac.jp/~g810370/linux-simd/ (Japanese).
|
|
*
|
|
* by KIMURA Takuhiro <kim@hannah.ipc.miyakyo-u.ac.jp> - until 31.Mar.1999
|
|
* <kim@comtec.co.jp> - after 1.Apr.1999
|
|
*
|
|
* Modified for use with MPlayer, for details see the changelog at
|
