Thermal-aware phase-based tuning of embedded systems

Abstract

Due to embedded systems' stringent design constraints, much prior work focused on optimizing energy consumption and/or performance. However, since embedded systems have fewer cooling options, rising temperature, and thus temperature optimization, is an emergent concern. We present thermal-aware phase-based tuning--TaPT--that determines Pareto optimal configurations for fine-grained execution time, energy, and temperature tradeoffs. Results show that TaPT reduces execution time, energy, and temperature by as much as 5%, 30%, and 25%, respectively, while adhering to designer-specified design constraints.
