Abstract
Dynamic voltage scaling (DVS) is the scheduling algorithm that changes the operating clock frequency of the processor according to the supplied voltage. This is very effective method to improve the power efficiency of embedded systems which use operating system. In this paper, we apply dynamic voltage scaling scheme to scaling scheme of real-time operating system. This estimates the amount of the task which will executed next time slot, then adjust the supplying voltage and clock frequency to improve system performance.
