GNU Radio works in 2 ways with PicoZed SDR
- Running directly on the Zynq PS7 processors ... works, but slow.
- Running on a host PC with the IIO plugin (gr-iio) ... preferred setup.
The 2nd method transfers data/control over Ethernet using LIBIIO. There are also convenient source/sink example blocks for FMCOMMS2 that work with PicoZed SDR.
