p9 Energy-Efficient Real-Time Task Scheduling with Temperature-Dependent Leakage

Abstract—Leakage power consumption contributes significantly
to the overall power dissipation for systems that are
manufactured in advanced deep sub-micron technology.

I. INTRODUCTION
Due to the urgent demand to prolong the life time of
batteries in embedded systems and to reduce power bills
for cutting the maintenance cost in server systems, power
management has become a prominent system design issue.

Recently, it has been shown that leakage current is highly
dependent upon the temperature and it goes up rapidly when
the temperature increases [7], [8]. For example, the leakage
current in 65nm technology in [7] will increase by 21%

This paper explores how to execute a given periodic workload
under its timing constraint on a processor so that the
energy consumption is minimized, where the leakage current
is temperature-dependent.
when the temperature is raised from 60◦C to 80◦C.
