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 --- 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.? --- Quote End --- Alera fft supports complex input/output f your input is real only then your imag is zero but fft output will be complex. You can't create imag input if you don' have it(it is zero if you don't have it).
