It would be ideal if we could trick the DSP into thinking TRV11 (or
whatever model number) was its memory.  The DSP would have to have
more of a local bus than a memory bus so that we could insert wait
states.

Another option would be to give the DSP a small local memory and have
TRV11 force-feed streams in and out.
