Hello I am trying to compute DFT using FFT in BF535. My need is to compute DFT of about 1 megasamples(1 million points). But since I'm very new to the field and am using a DSP for the first time, I do not know whether this is possible. If it is possible using BF535, how much time does it take to do it? Thank you.
