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

Subject: TMS320C20 C-compiler?
Hi,
a friend from our german Robotron comuter Forum gave me an U320C20 Chip
that was made in the former GDR bei ZMD Dresden. It is a copy of the
TMS320C20.
I got that Chip to do something with it, not to display it somewhere.
Maybe I can build a wirewrap board with it, but I want to program the
firmware in C.
Now I'm searching for an C Compiler that supports it, gcc does'nt
unfortunately, there is some support for the TMS320C3x and 320C4x
Processors which are floating point variants, the C20 is a Integer
processor w/o fp.
I know that there must be at least a TI C Cross-Compiler has existed
for Dos, Solaris and other OS.
Has someone a usable copy from such a thing?
Kind Regards,
Holm
