摘要：Hybrid electro-optical Network-on-Chip (HOE_ NoC) has recently been proposed to solve the problem of large scale interconnection. Although optical links in HOE_NoC provide high bandwidth and low latency for global communication, large static power consumed by laser and thermal tuning is also introduced. This leads to low power efficiency when the global traffic load is low. Anyway, for different application, traffic distribution in space and time may differ largely. It is necessary to dynamically provide optical link bandwidth to make the power efficiency keep high under all traffic distribution. In this paper, we propose a reconfigurable HOE_NoC architecture, in which, topology of electronic NoC is kept unchanged while the optical links can be reconfigured by dynamically throttling optical node. Experiments shown that compared to the electronic network under 64 nodes, latency has been reduced by 51%, while the throughput has been improved by 14%, the per-bit energy consumption has been reduced by about 26%.
