[Discuss-gnuradio] RFNoc and data rates

[Simon Olvhammar]

Hello,

I have a question regarding RFnoc and the USRP x310 FPGA capabilities.
We currently have a working GnuRadio application used for astronomy 
observations and are looking to get several more devices for integration 
in other systems.

However the data rates are high and CPU loads as well, thus we would 
like to move the application to the FPGA.
In the GnuRadio application we basically take the FFT of the signal and 
store it to files.
In Python we average the stored FFT:s, in terms of file size this is 
then reducing, for example a 200 MB file with FFT:s to a couple of KB. 
We would like to do the latter in the FPGA using RFNoc. This would then 
eliminate the need for expensive PCIe and Ethernet equipment for the 
high data rates.
My question is, is this possible using current RFnoc blocks?, with for 
example an average block?

Also wondering if a 8k channel FFT block might be expected in RFNoc 
anytime soon?

Best regards
Simon
