Hi Dan, I was unaware that the compiler was able to remove unused logic, that's pretty useful. What I need is one real input to one complex output, so I'll check Nitish model and import it to ROACH2 if I need to, thanks for the info. On a sidenote: It is possible still to join the slack? I

hi franco, are you looking for an FFT with a real input and complex output? you mentioned you are connected the unused inputs of the the biplex_real-4x to ground. this is useful, as the compiler should remove all the unused parts of the FFT, although it's probably not as resource efficient as a

[casper] One input FFT block [ROACH2]

2019-12-30 Thread Franco
Hello everyone, Is there an FFT block in the CASPER library (ROACH2) that can be used as 1 input -> 1 output? The closest thing I've found is the 'fft' block which has a minimum of 2 inputs. For now I'm using the fft_biplex_real-4x and zeroing 3 of the 4 inputs, but that's wasteful. I've also
