Know Of Any Good FFT Implementation Resources?

Hello,

I am currently in the conceptual stages of implementing an FFT function in
a relatively large FPGA (the thing has 6 multipliers that come for free, I
need the device anyway to do other stuff).

I've had cursory exposure to the FFT by reading Oppenheim/Schafer, but I'm
looking for some material that will go deeper with the concepts and that
will address practical implementation issues more thoroughly.

Does anyone here have experience with HW-based FFT implemenations?  If so,
do you have any favorite texts or websites that get into the gory details?

Thanks in advance,

Eric

I would check with the maker of the FPGA and see if they have any intellectual 
property for an FFT.  Even if you don't buy it from them, you can find out if 
it is possible and get some information to see if it's what you want.
