Can I use radix-2 first , divide 512 to two parts of 256 points, and then use radix-4 to calculate each 256 points. How to re-order the result ,is it different as normal ?(binary re-order)
Thanks in advance
 

What you mean you re-order the result?
You 're gonna write matlab code for calculating FFT or it's ... question ?
 

I need write a 512 point FFT in Verilog, I want use radix-2 first , divide 512 to two parts of 256 points, and then use radix-4 to calculate each 256 points. In the end ,after the final Butterfly ,it need binary re-order . I would like to know How to re-order the result? Is it different as radix-2 only arithmetic.
