[oc] C to VHDL parser/converter


Does anyone have a C to VHDL translator that can be used?  I need to 
convert my C code  to VHDL as a part of my thesis work. Please let me 
know if you can help.

Sounds very ambitious - I'd start by flashing some lights :-) I have to 
say the Celoxica's video demos are *very* impressive, generating VGA 
real-time from C impresses the pants off most softies, so a demo board 
with a RAMDAC on would be nice...

They generate directly to EDIF normally, although they do have a VHDL 
output flow now. YOu might get some info from some of the papers 
written about Handel-C when it was still an academic thing.

See my other reply on sequential processing...

You never know... Of course, if you open the source, Celoxica can nick 
your ideas, even without nicking the source-code can't they?

I've never objected to Handel-C actually :-) You maybe want to find 
something completely different... or not as you like!
