Abstract(in English) | In order to improve the efficiency of DVFS, it is important to properly distribute the slack time among tasks which is estimated by analyzing the task scheduling. In this paper, we proposed a method for slack time distribution called LFST (Leveling Frequency with Slack Time) to reduce the energy consumption of embedded real-time systems. The method uses two kinds of frequencies. One is the lowest frequency for guaranteeing deadline, and the other is a leveled frequency for analyzed tasks. Then, it selects the higher one from them and distributes it to the dispatched task so that energy can be reduced while guaranteeing the deadline restriction. The effectiveness of the LFST has been validated via experiments, and the results showed that maximal 64 % energy can be reduced comparing with fixed distribution rate of slack time. |
