I've got a couple of Blackfin kits (the Stamp and an EZ-Kit), it is a nice 
chip. Only problem is that the DSP is 16 bits, making the dynamic range a 
bit marginal. GNU tools for the SHARC are available, but need some work 
doing before they are usable. I might do a similar Blackfin board later on, 
it would be quite easy to design.
