Low Power NoC Switch Using Novel Adaptive Virtual Channels
Adaptive Virtual Channel (AVC) is proposed as a novel technique to achieve low power NoC switch. Power supply gating is employed to reduce the power dissipation of NoC switch without degrading network performance. Hierarchical multiplexing tree is used to achieve efficient AVC. AVC could reduce both dynamic and leakage power of the switch. Hierarchical multiplexing tree decreases the area of the switch which reduces the dynamic power by 60%. Using the leakage power reduction technique, the average leakage power consumption of Adaptive Virtual Channels is reduced by up to 97%.
