Hotspot Prevention Through Runtime Reconfiguration in Network-On-Chip

Abstract: Many existing thermal management techniques focus on reducing the overall power consumption of the chip, and do not address location-specific temperature problems referred to as hotspots. We propose the use of dynamic runtime reconfiguration to shift the hotspot-inducing computation periodically and make the thermal profile more uniform. Our analysis shows that dynamic reconfiguration is an effective technique in reducing hotspots for NoCs.
