Hyper-periodic thermal management for hard real-time systems

Abstract

This paper proposes hyper-period thermal management to minimize the peak temperature while guaranteeing hard real-time constraints for real-time systems. To establish the criterion of the optimal solution, a closed-form representation of the peak temperature is derived. With this formulation and the linear convex hull of an arrival curve, an approach which derives hyper-periodic thermal management schemes is proposed to minimize the peak temperature. Case studies show that our approach achieves lower peak temperature compared to previous work.
