The way I read the slides [1], these are the PRUs being used. Still the compiler seems to be proprietary (ick). Perhaps the whole instruction set is -- SOCs are strange beasts, full of patents, fears and secret sauces.

Note that the code on the PRUs is small enough that just doing it in assembler is quite easy. We used the C compiler as it is a bit easier to maintain.

There is a GCC backend for PRUs as well
