TMS320C20 C-compiler?

I remember programming a C20 or C25 back in 1988 or so, using a pretty mediocre TI compiler.? I recall having to look at the output not so much for buggy assembly output, but to identify any really egregiously inefficient code.? To my recollection, those chips were pretty easy to program in assembler, and that was pretty much necessary for any really timing critical code.??? (On the plus side, there was a great in-circuit emulator, and I used the lovable BRIEF editor, by underware) I think the 320C20 is the same underlying architecture as the 320C2xx series, and may be supported by some older, possibly free, versions of the TI development environment, Code Composer. Good luck! Dave
