Title of Paper:A Novel Non-cluster based architecture of hybrid electro-optical Network-on-Chip

Journal:IAENG Int. J. Comput. Sci.

Abstract:With the growing scale of Multi-Processor System-on-Chip, the large interconnection power and latency is becoming the bottleneck of the system performance. Hybrid electro-optical Network-on-Chip (NoC) is envisioned as a promising solution, which delivers global and local traffic in optical and electronic path respectively. Most of existing work is cluster based. They break up the node accessibility in the electronic link and thus might result in poor locality support, inability of fault tolerance or limited scalability. In this paper, we propose a novel non-cluster based hybrid electro-optical network architecture, in which topology of electronic NoC is maintained unchanged and an auxiliary optical NoC is built for the global communication speed up. Performance and power efficiency have been tested under 64 nodes and 100 nodes scale network. Experiments shown that, compared to the electronic network, throughput has been improved by 39% and 57%, while the latency has been reduced by 63% and 51%. When the network gets saturated, the per-bit energy consumption has been reduced by about 29% and 21%.
