No, it doesn't have the CPU in hardware. It does have multipliers,
MACs, & FIR filters that would be very useful in implementing a co
processor for a DSP to do the three functions. Not sure what the FIRs
could be used for.
But you said it was expensive.
sorry about that. xilinx says thats its no more than 30 usd. avnet did
not have a price.
