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%.
