Some questions about the old Motorola's dsp56k-gcc compiler and dsp563xx family - Avelino Herrera - Apr 21 8:23:00 2005
Hi, all. I am a newbie in the Motorola's DSP world and I have modified
the well known dsp56k-gcc port of the gcc GNU compiler (made by
Motorola) to use it in actual Linux boxes. I have a dsp56303 but the
dsp56k-gcc generates only dsp56000 code
- What are the essential differences between dsp56000 and dsp563xx
family?
- Is the dsp563xx family compatible with the dsp56000 code?
- What features of the dsp563xx family are throwed away running
dsp56000 code on it?
Thanks in advance and sorry about my poor english writting, I am spanish :-)

Hi, Stefan! :-)
> Which version of dsp56k-gc is it that you modified?
I modified the code located at
ftp://nic.funet.fi/pub/ham/dsp/dsp56k-tools/dsp56k-gcc.tar.Z derivate
from GCC 1.37.1 code, too.
> I might have sources of a newer compiler that supports the 56300 family,
> g563c -v says: g563c version Motorola 1.29 09-02-97 -- GNU 1.37.1
That sounds great!! 8-) How can I get that sources?
> Main difference between 56000 and 56300 is, besides faster execution,
> an extended instruction set, and as far as I know, none of the original
> 56000 opcodes have been discarded. So I think 56300 is 100% backwards

Thanks for the info and, please, say me how to obtain that g563c!! ^_^.
Thanks for your reply :-)
