You specifically setup the signal processing chain to do what you're saying here. You should be able to port the "guts" of the signal processing chain to the B200 without the need for RFNoC, per se. All the communication channels for getting the data streams to the host should live within UHD. This is a much more tractable problem than trying to get the entire RFNoC framework shoved into the B200. Good luck! Brian
