Dynamic power management for hard real-time systems

In “Dynamic power management for hard real-time systems,” Kai Huang, Luca Santinelli∗, Jian-Jia Chen, Lothar Thiele, and Giorgio C. Buttazzo at the Computer Engineering and Networks Laboratory, ETH Zurich, Switzerland, explore how to effectively reduce the energy consumption to handle event streams with hard real-time guarantees. Making use of Real-Time Calculus to describe the event arrival and resource service by arrival curves and service curves in the interval domain, they have developed algorithms to adaptively control the power mode of the device, postponing the processing of arrival events as late as possible.
