Crossbar Switch Arbitration with Traffic Control for NoC

NoC is a network of computing cores (IP cores) for processing information and routers for transferring data between IP cores. NoC has a lot of applications: it is used in communications, transport, in the Internet of Things ecosystems and the Internet of Drones. Routers are used to efficiently exchange messages between IP cores. One of the important functions of a router is arbitration. In this paper, we review the main arbitrage methods: Fixed Priority Arbitrage (FPA), Matrix Arbitrage, Round Robin Arbitrage (RRA), and some of its modifications for crossbar switching systems. We propose a conceptual framework for traffic control of NoC routers using arbitration techniques. Fairness as an important property of an arbitrator is considered. Different approaches have been proposed and some have been justified. The comparison of the simulated data shows that the results are in good agreement with both available experimental data and proposed models in the literature.
