전압변화에 의한 에너지 오버헤드를 고려하는 멀티프로세서 시스템을 위한 전압 조절 기법

Voltage Scaling for Multiprocessor Systems with Voltage Translation Energy Overhead

We propose a DVS technique for multiprocessor systems considering the energy consumed when translating voltage. We schedule periodic applications on two identical processors throughout a three-stage process; firstly, the computation energy consumption is minimized then the number of voltage translations is minimized. Finally, the result is compared with the schedule with no voltage translation and the one with smaller energy consumption is chosen. Overall, 10.6% energy reduction was achieved.
