摘　　要：提出一种基于活跃态的动态电源管理预测算法,充分利用了活跃态和空闲时间段的关系,并且加入动态自适应调节因子,不仅对较大变化的时间段预测误差小,而且能快速调整适应工作负载的变化。实验表明该算法优于传统算法。A predictive shutdown method based on active period was proposed. This method utilized the relationship between active period and idle period, and also imported the dynamic adaptive factor, Not only does it improve the prediction accuracy of idle periods which change greatly, but also adjusts and adapts to the change in workload quickly. Experiments show that this method achieves better performance and energy saving than traditional ones.
