Abstract

The application of multi-core processors in the embedded power terminal system can significantly improve the system performance, whereas will also bring about the increasing of the reaction time and the energy consumption. Aiming at the operating characteristics of the power industrial control terminal system, this paper proposes a time-trigger-based energy-saving scheduling method for multi-core systems. An intelligent scheduling scheme is established to ensure the requirements of real-time performance for multi-core systems. Also, two common system-level energy management technologies, such as the dynamic voltage and frequency regulation (DVFS) and dynamic power management (DPM), are adopted to reduce the power consumption of multi-core processors.
