4096-FFT-FPGA

[Harishkanmani]

Can any one explain me the concept of implementing FFT in labview FPGA.

I understood the basic concept of FFT

But I have no idea how to implement it without using inbuilt FFT

Can anyone share the logic? 

[Terry_ALE]

Right-click on the FFT (when on the block diagram) and select "Convert to subVI"

Are you looking to change the FFT functionality to do something different?

[Harishkanmani]

That's an inbuilt function

I need to develope on own for practice purpose

It is unlikely that you can beat the built-in IP, but from the size restrictions, they most likely use the Cooley-Tukey Radix-2 algorithm. (or higher radix).

There are plenty of references, for example start reading here.

Hardware implementations of FFT have been around for over 50 years. Here's another good reference.

Good luck. Seems like a nice exercise, but be careful about picking suitable datatypes and structures.

Can you help me in understanding this logic 

Still I can't able to understand
