[comp.sys.next] DSP modem implementations

Somebody recently enquired about the feasability of implementing a 9600 baud
modem using the DSP.  Someone else wanted to know what the hardware and software
overhead was.

I can't directly answer these questions, but I remember that in one of the
volumes from one of IEEE ISCAS (Internat'l Symposium on Circuits & Systems)
from this year (yeah, i know, that probably only narrows it down to about
twelve huge volumes) contains a description of a fast modem implemented using
a TI DSP chip.  Ok, ok, so its not the 56000.  However, the paper does give
an idea of the hardware overhead--i believe all they needed was pulse shaping
filters.  I don't have the time to go digging thru stacks and stacks of
conference proceedings (anymore), but I'm sure someone out there does and can
post the exact reference.
