It's my understanding that the current disassembler for this hardward is not working properly, so you can't program kernels in ISA. If you are able to get some ISA code working I would love to see some samples.
I guess you might be able to use the ISA to help optimize your IL or Brook+ code; however, you then still need to have a pretty solid understanding of the optimizations that are taking place within the CAL compiler.
