As Thomas says, there is plenty of time to load coefficients from
external memory to internal memory for processing. A while back,
Analog Devices offered a Blackfin eval system for 99�, which would
have easily covered all your needs (perhaps you can still pick one up
somewhere).

I'm not familiar with the TI processors.

Good luck and lots of fun!

The $99/99� Blackfin became available again after the first offer
expired. Maybe it is still available.
