| Abstract(in English) | In the field of Real-Time embedded systems, both of high-performance and low-power consumption are required. In this paper, we propose an algorithm to make utilization of logical processors even in order to improve schedulability and achieve efficient Real-Time Static Volatage and Frequency Scaling (RT-SVFS) with Instructions Per Clock cycle (IPC) Control mechanism which controlsthe thread execution speed. In addition, we also propose a method of Real-Time Dynamic Voltage and Frequency Scaling (RT-DVFS) that can maintain executed time of tasks with dealing with the efficiency of task executing by IPC control. According to the simulation results, the proposed techques improve schedulability and power consumptions compared by the existing techniques. |
