This is the official home page of the MMX Emulation Library Project for Linux/x86. Here the German mirror. And here the French translation.

It works only on Linux, and on Intel compatible processors, for the moment.

FAQ: MMX-EMU does not work under Windows, and we don't know about any equivalent package for Windows, sorry. Please do not send us mails about this, we won't answer them.

This library provides a simple way to execute (but slowly) binaries that use MMX instructions, on processors that do not support them.

It can be used if you want to develop MMX code, or execute MMX binaries, on a non-MMX Intel compatible CPU. Note that well written MMX binaries should contain the equivalent non-MMX code, since the emulation will always be really slow, and MMX code is all about speed.

The emulator also contains emulation code for Cyrix and AMD variants of MMX (EMMX and 3DNow!).

Source code to download (under GNU's Library General Public License):

• mmx-emu-0.6.tar.gz : 2nd beta release. 3DNow! and EMMX support added. Found bugs fixed.
• mmx-emu-0.5.tar.gz : 1st beta release. It should emulate correctly all the Intel MMX instructions.
• mmx-emu-0.2.tar.gz : 2nd alpha release
• mmx-emu-0.1.tar.gz : 1st alpha release

• mmx-emu-0.6.1-patch : a patch provided by Saisanthosh Balakrishnan against 0.6 that you may find useful.

Mailing-list:

• mmx-emu at openhardware.org doesn't work anymore.
