If I follow you right, I think you are mistaken on this about the 56K.
To save silicon, you can do as many of us do and use a single memory 
space addressed by X, Y, and P memory.

Yes, it most definitely does.  By this I presume you mean allowing an ALU or
multiply-accumulate instruction in parallel with two memory reads or writes.
This it will do.

The DSP56001 has two serial ports and a host interface port for use in
communicating with a master processor.  One serial port is asynch, the
other synch.  The host port supports addressable, networked DSPs.

Note: I work for Motorola Cellular, not DSP Operations,
 so I only USE the 56K.

  Don't feel paranoid; when we're out to get you, you won't have the vaguest 
    idea what's going on.  Corollary:  When you feel safe, that's when you 
                             should feel paranoid.
