As long as there is some way, we can exchange data with the DSP and
exchange it's programs, which isn't all that slow, I have to
disagree.

TI and other companies sell so called "Evaluation Boards" or
"Evaluation Modules". The smallest ones are attached via Parallel
Port or soon via USB. We have two different PCI boards with TI chips.
One supports up to 4 DSPs and thus is capable of doing even video
processing, but its just a C44 board.
Both boards support standalone running of the DSP, while not
plugged into a PCI slot, but having their power lines wired of
course. The newer one with an C66 has even a A/D and D/A
converter. (so it's also a bloated sound card ;-)).
They are made for developing applications for the DSP and
examining its behavior via hardware debugging.
In short: They have lots of useless features.
Price: We got them donated, but they cost about half a car, if
you get them new, we have been told.
