Leakage-aware real-time scheduling for maximal temperature minimization
Gang Quan, Shangping Ren · ACM SIGBED Review · 2010
Thermal management problem has become a prominent issue as power consumption continues to grow exponentially. The leakage/temperature dependency becomes critical in power and thermal aware design as the processor continues to evolve into the the deep sub-micron domain. This paper seeks to explore fundamental principles in thermal aware design when taking the leakage/temperature dependency into considerations. We show and formally prove that, under certain realistic conditions, using the lowest constant processor speed that can guarantee deadlines of all real-time tasks is an optimal method to minimize the maximal temperature for a real-time system. We also use empirical results to justify the validation of this conclusion. We then discuss the possible future extension of this work.
