I am interested in two things. 1) information about the FASTEC AT&T
DSP32 board  2) experiences and applications that other users have
implemented with DSP boards and/or with array coprocessor boards.

Fastec is a company out of Boulder CO. and sent me a flier about
their board which uses the AT&T DSP32 chip. They have software available
to compile BASIC commands into DSP32 microcode. Is the software any
good? What knids of things can I do with such a beastie?  Our research
group studies the mechanics of the cochlea (inner ear) and run a model
of the cochlea consisting of 100-1000 fluid coupled nonlinear VanderPol
oscillators.  Our code is essentially a timestep simulation which
alternates between solving with backsubstitution a matrix of the 
displacements to get the pressure at each site along the cochlea, and then 
feeding these pressures into a 2nd order diff eq. to get the next set of
displacements and velocities. 

Please e-mail your responses.  I AM interested in your experience
with any of the coprocessor boards whether they are DSP or not.
thanks
