Multiple use-case Chip Multi-Processor (CMP) applications require adaptive on-chip communication fabrics to cope with changing use-case performance needs. Networks-on-Chip (NoC) have recently gained popularity as scalable and adaptive on-chip communication fabrics, but suffer from prohibitive power dissipation. In this paper, the authors propose UCPHOTON, a novel hybrid photonic NoC communication architecture optimized to cope with the variable bandwidth and latency constraints of multiple use-case applications implemented on CMPs. Their detailed experimental results indicate that UC-PHOTON can effectively adapt to meet diverse use-case traffic requirements and optimize energy delay product and power dissipation, with scaling CMP core count and multiple use-case complexity.
