Hi Louis, The E310 has limited FPGA resources, so you will quickly run into resource utilization issues when trying to include multiple RFNoC blocks. Also, the FFT, Window, and Schmidl Cox RFNoC blocks focus on usability, so their implementations are less optimized and likely use more resources than necessary for your application. I would suggest combining those blocks into your own custom RFNoC block and removing features you don't need for your specific application. Another option would be getting an E320 which has a much larger FPGA.
