Re: [Discuss-gnuradio] Faster FPGA clock rates

[CEL]

Dear Maria,

no, GNU Radio is a pure software framework; it doesn't directly talk to
any hardware, but has a gr-uhd component which uses UHD, Ettus' own
driver, to talk to your USRP.

Anyway, you can't simply reprogram the FPGA to give you higher clock
rates. 61.44 MHz is physically the most that the interface on the radio
chip on the B210 can do. There's zero way around that.

To answer your question "which programming language would I need to
modify an Ettus USRP's FPGA image": None, you would need to learn
*hardware description languages*, especially Verilog. If you haven't
worked with those before, it will be quite different from programming
Python or C++ or Matlab. But again, an FPGA modification couldn't do
anything here.

Best regards,
Marcus
