See the book CMOS VLSI Design: A Circuits and Systems Perspective (3rd Edition)
has some info on FFT on FPGA for 128 points. May you get some hints from this book!

Hi yongqin2005,

The best source about how to implement FFT in the FPGA is comp.arch.fpga newsgroup. You will not find source code for FFT over there but lots of good advices about implementation.

You could try also the "Digital Signal Processing with Field Programmable Gate Arrays" book by Uwe Meyer-Baese ( published by Springer, second edition). It has a chapter about Fourier Transforms.

Also you can go to www.opencores.org and see how their FFT works.

good luck,

To add some reference.

Please see this paper: http://www.andraka.com/files/HPEC2006.pdf
You can find there a really good description of the FFT in the FPGA. After reading it you should get some general knowledge about FFT algorithms which are best suited for FPGA realization.

Good luck.
