Hey, I haven''t actually learned any MMX yet... but I''m wondering what computers support it (i.e. first Pentium Mhz)? Pretty old, probably pretty common... so maybe I ca require it? On a side note, afaik the inline ASM in VC5 doesn''t support MMX and all that... I can get MASM from the DDK, any ideas on how to set that up so it works from Visual Studio? Thanks, Nathan. nathany.com

The first pentiums didn''t support MMX, i think it was only until the Pentium 200 (or 166) MHz that MMX came out. It probably won''t be a bad idea to require it because all Pentium 2s & 3s support it, and hardly anyone has a processor less than 200MHz

Yah, chances are my game will end up requiring a 166/200 Mhz processor anyway.

Anybody have any idea on when MMX first appeared on Cyrix and AMD chips?

I think there are MMX and non-MMX versions of the P166 and P200. I think AMD processors support MMX since K6-II.

AMD K6-200 supports MMX.

3DNow! = MMX compatible? Or did it support both?


Two separate, but similar things. And they supported both.

Thanks everyone, sounds like basically a 200 Mhz machine as a target will have MMX built in already. Could always do an unMMX version of my routines, but for a freeware game... nah

Now I just need to learn how to code it... any urls, book titles, resources welcome...

Thanks, Nathan

Intels website. They have some great examples plus the whole reference manual and all those goodies

I found some stuff their. Guess that''s what it will have to be, because all the books on the topic seem to be out of print.

Right now I just downloaded MASM 6.14 from Microsoft''s web site. I''m trying to figure out the custom build stuff in VC5 so I can use DevStudio for both C/ASM. Fun stuff
