I know nothing about DSP, but here is some information from the 
FAQ in comp.dsp:




DSP56001: 20.5, 27, or 32 MHz fixed point DSP.  24 bit data bus, 16 bit
address bus, 56 bit accumulators (2), host interface port, serial ports (2),
general purpose I/O pins, timer.  Harvard architecture.  512 words program
RAM, 512 words data RAM on chip.

DSP56000: Mask-programmed version of DSP56001.



A free assembler for the Motorola DSP56000 exists, thanks to Quinn
Jensen, jensenq@qcj.icon.com.  The current version is 1.1, and
it is posted to alt.sources, so look for it on mirrors of this
newsgroup (like wuarchive.wustl.edu).


There are  two separate  compiler sources for the Motorola DSP56000.
One is the port of gcc 1.40 done by Andrew Sterian (ASTERIAN@BNR.CA)
and the other is a port of  gcc 1.37.1 done by Motorola and returned
to the FSF.  These may be portable to gcc2.x.x with  some  effort
required.  Neither of these comes with an assembler, but you can get
a free DSP56k assembler elsewhere (see above).  For more information
on the Motorola compilers try contacting Jeff Enderwick (jeff@dsp.sps.mot.com).

From Andrew Sterian, ASTERIAN@BNR.CA:

The source code for the Moto compiler is available on nic.funet.fi. 
My own DSP56K port has bowed to Motorola's version.  My DSP56156 port is
still the only DSP56156 compiler around and I have just released an updated
version of it.  Both this compiler and the previous incarnation are archived
on wuarchive.wustl.edu (in the usenet/alt.sources directory) amongst other
places.



Q3.2.3: Where can I get algorithms and libraries for Motorola DSPs?
        What is the number for the Motorola DSP BBS?

Motorola runs "Dr. Bub", a bulletin board for DSPs containing source code
for various libraries and algorithms.  You can call it at (512) 891-3771
(1200 bps 212A), (512) 891-3772 (V.22), and (512) 891-3773 (2400 bps V.22bis).
Format is 7 data bits, even parity, 1 stop bit).  Log in as "guest", terminal
type of "dumb" if you have no screen emulation capabilities.

Alternatively, Dr. BuB is mirrored on the following sites:

calvin.stanford.edu   (36.14.0.43)     in   /motorola
bode.ee.ualberta.ca   (129.128.16.96)  in   /pub/dos/motorola
nic.funet.fi          (128.214.6.100)  in   /pub/misc/motorola
doc.ic.ac.uk          (146.169.3.7)    in   
/computing/systems/motorola/digital-signal-processing/dr.bub.sources

Also try nic.funet.fi in /pub/ham/dsp for a lot of good stuff on 
communications uses, including some hardware.
