I've just began to learn C programming, and CPU extentions are long way for me to go... My posts of the introductions into Japanese programs have two problem: my English and my knowledge. Hmm, I should learn the extentions... Thanks!

It's not like SSE is intended to replace MMX. They are two distinct sets of instructions. Why limit yourself to SSE, when you have both, MMX and SSE, available?
You would only make your assembly code slower than it could be...

Oh, yeah, you have a point. I'll ask him about that. Thanks!

That article is easy to understand for me, thanks! OK. It helps me how he came to think MMX can't use on 64bit Windows, then I can tell him about the discussion on MMX here easier.

Certainly. You're the gentleman.
But I think the discussion here helps him very well. And, don't worry, however you tell him to do anything he doesn't want to, he won't do
