The main current stumbling block to large FFTs in RFNOC is that the FFT output has to be able to fit into a single transport packet, andOn 03/03/2016 05:21 AM, Simon Olvhammar wrote:
Hi,
I'm wondering what it would take to modify the current FFT RFNoC block to be able to compute a 8192 channel FFT. Someone that can guide me in the right direction? I'm a quite experienced programmer, however not in HDL.
Best regards
Simon
that is limited to 9000 bytes, which pretty-much limits you to 2048-bin FFTs. There will be work in the future to allow FFT outputs in
RFNOC to span multiple packets.
