OXiGen is a tool that automates configuring FPGAs by taking high-level C/C++ code as input, performing optimizations, and generating an optimized bitstream file for a Xilinx FPGA. FPGAs offer competitive performance and power efficiency but configuring them typically requires using different toolchains and languages. OXiGen addresses this by handling all intermediate steps to configure the FPGA from an input program. It works by taking C/C++ code through frontend processing, optimizations in the backend, and outputting a bitstream file for the Xilinx FPGA. More details and the tool's source code can be found on its Bitbucket repository.
