In this thread http://www.psp-programming.com/forums/index.php/topic,3360.15.html
Raphael, master programmer that he is, gave his version of a fast memcpy that uses the VFPU's cache to speed up a cache write.

Does anybody else have information about the VFPU cache? Does a separate VFPU cache really exist? What are the rules for this cache?

I'm thinking of adapting Raphael's memcpy and making all large copies use the VFPU cache if such a cache really exists, so that the main cache doesn't become polluted from streaming data. Does that sound like a good plan?
