Adaptive CDMA based multicast method for photonic networks on chip

Abstract

Networks on Chip (NoC) are a scalable solution to the growing problem of multicore data communication. One of the major challenges in multicore NoCs is that the redundant multicast invalidations can easily increase the load on communication resources cumulatively and lower the overall performance of the chip. In this paper we propose a novel technique to minimize the number of redundant invalidations. Moreover, Silicon-photonics is applied in NoC to lower the energy-delay product. Performance results show 15% improvement over an electrical mesh NoC and 13% improvements over a state of the art photonic NoC.
