FlooNoC: A Fast, Low-Overhead On-chip Network¶

FlooNoC, is a Network-on-Chip (NoC) research project, which is part of the PULP (Parallel Ultra-Low Power) Platform. The main idea behind FlooNoC is to provide a scalable high-performance NoC for non-coherent systems. FlooNoC was mainly designed to interface with AXI4+ATOPs, but can easily be extended to other On-Chip protocols. FlooNoC already provides network interface IPs (named chimneys) for AXI4 protocol, which converts to a custom-link level protocol that provides significantly better scalability than AXI4. FlooNoC also includes protocol-agnostic routers based on the custom link-level protocol to transport payloads. Finally, FlooNoC also include additional NoC components to assemble a complete NoC in a modular fashion. FlooNoC is also highly flexible and supports a wide variety of topologies and routing algorithms. A Network generation framework called FlooGen makes it possible to easily generate entire networks based on a simple configuration file.
