It depends on your computer: it can be a MMX memcpy, a 3DNow memcpy or a SSE memcpy.
BTW, what are you doing, exactly?
A pointer switch every 10ms would be way more efficient. Why can't you do it?
Or are you doing video double buffering? In this case, you can do the memcpy only on video retrace, not every 10ms. Or you could do an AGP memory transfer, using DirectX or DirectVideo.
You won't be able to speed up this so much. The newest machines have a processor of 3.2Ghz and a FSB of 2x400 Mhz, that means your processor clock is 8 times your memories' clock; in simple words: memory is becoming slower and slower...

Perl combines all the worst aspects of C and Lisp: a billion different sublanguages in one monolithic executable. It combines the power of C with the readability of PostScript. -- Jamie Zawinski
