When Eric Christensen and I were speaking at Georgia Tech, one of the big points we'd made was that on the SPUs, "Code is just data." There's nothing special about it and really no reason at all why you shouldn't just be dynamically uploading the code you need to transform the data right along with the data. Using the OS provided system for launching SPUs and SPU code may carry too much overhead though. And sometimes dynamic code loading libraries are just over-complicated. So we've written up a little document to give those of you that want to dynamically load SPU fragments a really straightforward and simple way to do just that.
