RTNoC: A Simulation Tool for Real-Time Communication Scheduling on Networks-on-Chips

Networks-on-chips (NoC) is accepted as the most promising on-chip communication infrastructure to solve the communication bottleneck of MPSoCs. Currently, research on real-time communication scheduling on NoCs is immature, and no existing simulation tool can satisfy the requirements of simulating real-time communication scheduling on NoCs. Such a simulator is highly desirable for the research on NoC-based real-time systems. In this paper, we designed RTNoC, a realtime communication scheduling simulator on wormhole-switched NoCs. We also use this simulator to evaluate the real-time performance of different scheduling algorithms with periodic task sets. Experiment results show that RTNoC is a good tool to motivate research on real-time communication scheduling.
