Honored ContributorGenerate Real FFT IP
Hi, I would like to generate a real 64 point FFT. i.e. it takes 64 real input and generates 32 complex output bins. As per myy initial analysis, Altera MEgacore generates only complex...

Honored Contributor --- Quote Start --- just set imaginary input of altera ftt to zeros --- Quote End --- Thanks Kaz.. I understand setting imaginary to zero is an option. But it need a 64 point complex FFT, which I feel is unnecessary. Also I found a paper where it can do using 32 point FFT(in my example), by making odd and even values as real and imaginary. But it needs some additional logic to be implemented on out put of FFT. What I was interested is whether Altera provides such whole solution itself.?
