PhoNoCMap: An application mapping tool for photonic networks-on-chip

While providing a promising solution for high-performance on-chip communication, photonic networks-on-chip suffer from insertion loss and crosstalk noise, which may severely constrain their scalability. In this paper, we introduce a methodology and a related tool, PhoNoCMap, for the design space exploration of optical NoCs mapping solutions, which automatically assigns application tasks to the nodes of a generic photonic NoC architecture such that the worst-case either insertion loss or crosstalk noise are minimized. The experimental results show significant benefits in terms of insertion loss and crosstalk noise, allowing improved network scalability.
