I guess the question is if this is the use of SIMD code or is it code that takes care of the threading for you. I've looked at AMD's packages in the past and didn't find anything useful as the library routines were more application-specific. But if they put out some nice multimedia libraries, then I'll take a look.
Intel currently does this but they aren't free (my recollection).
The best multimedia libraries that were free that I've seen came from Apples Developer stuff.
