Reliability-Aware Power Management for Real-Time Embedded Systems

Abstract

The improvements in the performance of modern computing systems have resulted in drastic in- creases in power densities. For battery-operated em- bedded devices with limited energy budget, energy is now considered a first-class system resource and power- aware computing has recently become an important re- search area. However, as a widely-deployed power management technique, Dynamic Voltage and Frequen- cy Scaling (DVFS) was recently shown to have negative effects on system reliability. In this talk, I will discuss a reliability-aware power management (RAPM) framework, which can systematically exploit static and dynamic slack to minimize energy consumption while preserving system reliability for various real-time systems.
