摘要
提出一种实时功耗管理算法,对当前空闲时间长度进行预测,并应用Timeout方法进行修正,以确定是否进入睡眠模式。在IBM硬盘管理的应用中,实验表明该方法具有较少的错误关闭次数和错误等待次数,因而有效地降低了功耗。
In this paper, a novel dynamic power management is presented based on predictive and timeout policies. Online idle period is predicted according to previous idle period and previous prediction. In order to cope with errors aroused by a long sudden idle period, a adaptive coefficient to avoid overestimate the online idle period has been provided. On the other hand, timeout policy is taken to reclaim shutdown in the underestimate situation. Experimental results show that this algorithm outperforms other advanced dynamic power management policies because of less wrong shutdown times and wrong waiting times.
