| Summary: | 碩士 === 國立臺灣大學 === 電機工程學研究所 === 95 === The thesis introduces a new optimization problem called dynamic power mode switching (DPMS) in real-time system. In order to reduce the static power of system, we shutdown the system components in idle by means of some particular power modes which represent combinations of system components on/off states. The DPMS optimization problem indicates a new research direction of the energy-saving techniques on processor.
Aiming at the DPMS optimization problem, we propose an algorithm based on the well-known earliest deadline first (EDF) scheduling. It describes how to exploit the spare system utilization to reduce energy consumption during the operation of power mode switching and guarantee all tasks meet their deadlines at the same time. The results show that our algorithm is energy efficient and effective.
