Hi Derek, Thank you for referring to the RFNoC. I think it covers most DSP operations.
However, the things I want to add is not DSP operation but eCPRI. Do you have any future plan to support eCPRI? eCPRI is basically formatted messages over standard Ethernet. Therefore, I am thinking of customizing the firmware.
