I think that we should take it as a given that for a sequential
processor that it would be cheaper to purchase one (probably a DSP)
rather than making one with a FPGA. OTOH, a massively parallel
operation like DCT/IDCT or special purpose functions like YUV <> RGB and
image scaling would better be realized with something else -- a FPGA
would be one option (probably the best option since discrete chips seem
to be on their way out).
the spartan 3a dsp has a bunch of dsp's in it.
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.
