FFT implementation

[Mr plexi]

Good evening,
I have to implement a monodimensional 16 points FFT, radix-4,
Decimate In Time.

Can anybody tells me where can I find some vhdl code for this project?

Thanks so much.
MrP

You want to implement 16 point FFT and you are asking the code for it.
may be you can start by asking the code for the adder used there.
