hi,
we are trying to implement an efficient aoutocorrelation in verilog and for this we need to find the FFT. what we are trying to do is (from wikipedia/efficient comp):
ac[n] = IFFT { FF{(x[n]} * FFT*{x[n]} }.
In this case does it matter how many points FFT we choose, because that we will take the IFFT, or does it lead to data loss? can you give us some tips on doing autocorrelation and/or FFT in verilog.
thanks
