Implementation of FFT on FPGA

I want to implement FFT on FPGA..
i am using the approach of Microblaze processor...
A to D converter will give the sine function in digital form to the FPGA kit then this Sine wave will be sent for FFT and after FFT the result ll be sent to LCD for display.
all this management ll be done by Microblaze processor...
is there any approach to implement FFT on FPGA?
Is my approach correct for real time processing...
Thanks

Re: Implementation of FFT on FPGA

There are multiple methods of implementing an FPGA-based FFT.

One technique is to use a software implementation by an FPGA-based processor. Another approach (likely more common) is to use a traditional fabric-based implementation. Here's one example.

I personally wouldn't consider displaying the data to an LCD to be "real-time" but I guess it could depend on the application.

Re: Implementation of FFT on FPGA

hi,

i could not find any of them at opencores...

i got the ip core for FFT at Xilinx ISE core generator ...

bt still to find the cores for ADC and VGA....

plz help me out precisely if u know....

thanks
