The dev tools I'm getting include assembler and C compiler, along with a simple OS and a good sized application specific (imaging) library.
But there are a lot of advantages to combining assembly and C with a scripting language. It's a lot more flexible. So, if I can do it, I will. The only current language that might work for the ADSP21xx DSP seems to be FORTH (and at least two different people have ported FORTH to these chips). The other alternatives are to roll my own (something I'd prefer not to do) or give up.
