Thermal/Performance Trade-Off in Network-on-Chip Architectures

Free registration required

Executive Summary

Multi-core architectures are a promising paradigm to exploit the huge integration density reached by high-performance systems. Indeed, integration density and technology scaling are causing undesirable operating temperatures, having net impact on reduced reliability and increased cooling costs. Dynamic Thermal Management (DTM) approaches have been proposed in literature to control temperature profile at run-time, while design-time approaches generally provide floor-plan-driven solutions to cope with temperature constraints. Nevertheless, a suitable approach to collect performance, thermal and reliability metrics has not been proposed, yet.
