I'd suggest to get the application notes from Motorola. They show
example schematics and give some details on programming. Motorola
also has a BBS where you can download example software including
the monitor program used on Motorolas development system.

As for hardware, it depends. If you build a small system, the 8x24bit
RAM from Motorola helps to make a very compact design. For me this
memory size wasn't sufficient, so I used 3 32kx8 chips.

Hope this helps,

Hi Raymond

Motorola offers quite a lot of paper about the DSP56000/1. Ask there for
literature. 
I'm designing a multi DSP system for parallel processing. As RAM I use
the Motorola DSPRAM MCM56824 (8k x 24 bit) plus common chips (32k x 8 bit)
for extended appliactions. Decoding is done via GALs (Lattice 20V8, 16V8).
This is a fast (some ns) and flexible way of decoding and partitioning.

As peripherals serve standard 68xxx devices, but they require different
bus signals and timings. This interface is done with GALs.

My IO devices are Crystal converters: CS4328 (2 x 18 bit D/A)
                                      CS5326 (2 x 16 bit A/D)

That`s all for the moment.. (I mean: good luck!)

	There is available as PD one design and software (mainly for radio
	amateur purposes) at nic.funet.fi (directory /pub/ham/dsp/packet).
	The schematics and documentation is available as PostScript form.
	The older revision uses TLC32044 codec and the newer version uses
	beautifull CS4215 stereo codec.
