An enhanced and embedded GNU radio flow

This paper presents a Zynq capable version of GNU Radio - an open-source rapid radio deployment tool - with an enhanced flow that utilizes the processing capability of FPGAs. This work features TFlow - an FPGA back-end compilation accelerator for instant FPGA assembly. The Xilinx Zynq FPGA architecture integrates the FPGA fabric and CPU onto a single chip, which eliminates the need for a controlling host computer; thus, providing a single, portable, low-power, embedded platform. By exploiting the computational advantages of FPGAs in the GNU Radio flow, a larger class of software defined radios can be implemented. Once the FPGA is programmed with a design, modules can be parameterized to realize an even larger class of applications and further solidify the concept of rapid assembly of software defined radios.
