Just curious, how much logic does each DDC (cordic, CIC, decimator) require? I'm trying to estimate how many would fit in an XC3S400. I think that currently the code uses the "free cordic multiply" with a cordic for each channel. Could we instead take the sin and cos off of a single cordic and use the hardware 18x18 multipliers in the Spartan 3? Would that be a savings?
