An autonomous-DVFS-enabled supply island architecture oil network-on-chip platforms is proposed. This architecture exploits the temporal and spatial network traffic variations in minimizing the communication energy while constraining the latency and supply management overhead. Each island is equipped with autonomous DVFS mechanism, which traces the local and nearby network conditions. In quantitative simulations with various types of representative traffic patterns, this approach achieves greater energy efficiency than two other low-energy architectures (typically 10% - 27% lower energy). With autonomous supply management oil a proper granularity as demonstrated in this study, the communication energy can be minimized in a scalable manner for many-core NoCs.
