Priority-based packet communication on a bus-shaped structure for FPGA-systems

We present an application tailored packed-based SoC communication system with one-hop communication between all entities, priority-based arbitration, broadcast and multicast support on a bus-shaped basis. It is located as a hybrid between NoC and bus approaches, closing the gap for mostly streaming-based systems with the need for highly flexible communication patterns and multicast messages that are below a certain size. The system is implemented and evaluated on a FPGA within a car-to-car communication gateway application.
