As Networks-on-Chip (NoCs) continue to consume a large fraction of the total chip power budget, dynamic voltage and frequency scaling (DVFS) has evolved into an integral part of NoC designs. Efficient DVFS relies on accurate predictions of future network state. Most previous approaches are reactive and based on network-centric metrics, such as buffer occupation and channel utilization. However, we find that there is little correlation between those metrics and subsequent NoC traffic, which… CONTINUE READING
