Best FFT implementation for FPGA/ASIC ???????

Dear All,
I have a problem with FFT. It needs a lot of gates to implements. Is there any optimized algorithm to implement FFT in FPGA/ ASIC ?

I read about FFT . there are several ways. Pipeline, Radix, Cordic ... But i want a good comparison between them.

I don't know what type of FFT you need to have, but for streaming FFT, take a look at Radix-2^2 FFT. It was easier to implement than radix-4 FFT, but had the same performance as radix-4.
