unfortunately the FPGA verilog source code isn't open source.. and I can't see any RF block diagram in the website
Some more questions because the website isn't clear:
- does the FPGA handle digital beamforming in the FPGA fabric? or it controls RF phase shifters for analog beamforming?
- will we have access to FPGA pin constraint file so we can write our own verilog
- can I get IQ samples from the antenna elements and run my own beamforming algorithm / calibration in a separate PC with possible GPU acceleration? or it will be bottlenecked by rpi5 gigabit ethernet?
- mrtnmcc 5mo agoYes the FPGA does digital beamforming and there will be published FPGA pin constraint files so you can write your own Verilog. For IQ samples, you can stream a continuous 60 MSPS IQ beam over the Ethernet, but for custom beamforming algorithms, the processing needs to be distributed across the FPGAs (for MoonRF it is a SERDES daisy chain, using the same FFC connectors as the links to the RPi-5). Yes I'll put some newer block diagrams on the website this week. Thanks for the reminder.
- minetest2048 5mo agoSounds good! Hopefully i can buy one and play around with it
