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
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, and
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.
