 I have recently been given a task to write a Viterbi decoder for the TMS320C25.
I have a copy of a variable constraint length version from Sklar, _Digital
Communications_, and would have to translate it into C, then use the C
compiler to get TMS code out.  Since I've heard some horror stories about
the C compiler and its inability to optimize its code, I was hoping to find
someone who has already gone through this.  The algorithm itself need not
be exactly what I'm looking for (i.e. Sklar, 3202x family).

Thanks.

Horror story about 'C' compiler for the TMS320xxx

A friend of mine was using the Texas C Compiler for a student project
at Surrey University. He was having a number of problems, and got onto
TI about it, but their customer support was not too hot seeing as he
was a mere student (read 'pleb':-). 

He was developing his system for MSK carrier recovery on a
Loughborough Sound Images board, so he 'phoned them in search of the
assistance which had thus far eluded him.

He was told: 'Oh yeah, we don't use the C compiler anymore, because
no-one ever got it to work'.

He re-started basically from scratch, which involved much desperate
assembly-code hacking needing to be done to get his project in in time.

Ho Hum,

Andy.
