Hi Erik, so, GNU Radio *itself* is purely host-based software; in other words, you'd be processing 100s of MHz on the poor Zynq's ARM (will not even remotely happen).
What you'd need is to do the signal processing in the FPGA, for the most significant part. After you've selected your channel and reduced your sampling rate to that, yes, GNU Radio could very well deal with that data (if the ARM CPU is up for that). There's an accelerator framework, that Ettus developed for their Zynq- based products, called RFNoC. That works relatively nicely with GNU Radio. Pretty sure Analog Devices themselves also have libiio- compatible ways of signal (pre)processing on Zynqs, but I'm not knowledgeable about that at all. Which FPGA would fit your bill depends on the kind of signal processing you'd need to do. I'd assume the 7000 series Zynq would be a bit on the limits of its bandwidths dealing with 450 MS/s.
