Hotspot Prevention Through Runtime Reconfiguration in Network-On-Chip

TL;DR

This paper proposes a dynamic runtime reconfiguration method for Network-On-Chip systems to effectively reduce hotspots by periodically shifting computation, leading to more uniform thermal profiles.

Contribution

It introduces a novel approach using runtime reconfiguration to address location-specific hotspots in NoCs, which was not the focus of prior thermal management techniques.

Findings

Reconfiguration reduces hotspot intensity

Thermal profile becomes more uniform

Effective in NoC environments

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.
