Network-on-chips (NoCs) continues to be the choice of communication fabric in multicore architectures because the NoC effectively combines the resource efficiency of the bus with the parallelizability of the crossbar. As NoC suffers from both high static and dynamic energy consumption, power-gating and dynamic voltage and frequency scaling (DVFS) have been proposed in the literature to improve energy-efficiency. In this work, we propose DozzNoC, an adaptable power management technique that effectively combines power-gating and DVFS techniques to target both static power and dynamic energy reduction with a single inductor multiple output (SIMO) voltage regulator. The proposed power management design is further enhanced by machine learning techniques that predict future traffic load for proactive DVFS mode selection. DozzNoC utilizes a SIMO voltage regulator scheme that allows for fast, low-powered, and independently power-gated or voltage scaled routers such that each router and its outgoing links share the same voltage/frequency domain. Our simulation results using PARSEC and Splash-2 benchmarks on an 8 × 8 mesh network show that for a decrease of 7% in throughput, we can achieve an average dynamic energy savings of 25% and an average static power reduction of 53%.
