NI-USRP utilizes portions of UHD and allows for programming in LabVIEW, NI’s flagship
intuitive development environment. The abstracted design environment helps accelerate the
design of wireless systems and makes FPGA programming accessible to those without HDL
design expertise. Using LabVIEW, you have the option to program the FPGA and host in a
single development environment. Users have the option to customize the FPGA when using
NI-USRP.
UHD uses a common, open-source software interface that increases code portability, allowing
applications to transition to other USRP SDR platforms when development requirements
expand or new platforms are available. UHD offers cross-platform support for multiple
industry-standard development environments and frameworks, including GNU Radio and
MATLAB/Simulink.
