Hardware-Software Co-Design

Deploy hardware and software implementations of SDR algorithms on Xilinx® Zynq®-based radio hardware

With the Communications Toolbox™ Support Package for Xilinx Zynq-Based Radio, you can design an SDR algorithm in Simulink®, and then prototype your design on the Xilinx Zynq-based radio hardware. You can either deploy a hardware-software (HW/SW) co-design implementation partitioned between the ARM® processor and the FPGA fabric of the underlying system on chip (SoC), or prototype the design targeting the FPGA fabric only. The workflow is available in Simulink only.
