Description/Abstract

We present a novel co-design methodology for the synthesis of energy-efficient embedded systems. In particular, we concentrate on distributed embedded systems that accommodate several different applications within a single device, i.e., multimode embedded systems. Based on the key observation that operational modes are executed with different probabilities, that is, the system spends uneven amounts of time in the different modes, we develop a new co-design technique that exploits this property to significantly reduce energy dissipation. Energy and cost savings are achieved through a suitable synthesis process that yields better hardware-resource-sharing opportunities. We conduct several experiments, including a realistic smart phone example, that demonstrate the effectiveness of our approach. Reductions in power consumption of up to 64% are reported.
