NoxyGen

We present NoxyGen, a Network-On-Chip(NoC) design and evaluation tool which generates NoC RTL in Verilog and functionally validates generated RTL. NoxyGen comes with parameterizable NoC router built using modular latency-insensitive pipeline stages, facilitating easy modifications. We describe the internal micro-architecture and configurable parameters of the router. Network statistics can be obtained by running synthetic traffics. Evaluation with synthetic benchmarks shows the effectiveness and correctness of the generated NoC RTL design by NoxyGen. For prototyping, we build a multicore system with Xilinx Microblaze cores connected using NoC on an FPGA and run message-passing (MPI) applications. We make NoxyGen open-source so that it can be used by the scientific community for further research on NoC and prototype their proposals to be run on FPGA.
