摘要 面向层次化存储的DPM策略利用数据缓冲区实现请求集中从而延长PMC的空闲时间,可获得比传统策略更好的节能效果。在此基础上提出基于任务信息(task information based,TIB)的层次化存储DPM策略。TIB策略对任务的数据访问模式进一步细分,通过修改存储访问接口获知任务数据访问的模式,根据不同模式决定预读与替换算法,使策略具有更好的节能意识。 Storage hierarchy oriented DPM,which uses buffer to prolong idle time,can achieve lower power than traditional DPM policies.The paper proposes task information based（TIB） policy for storage hierarchy oriented DPM.TIB subdivides the data access mode of tasks and introduces them into policy by modifying access interface to make prefetching and replacement algorithm more energy aware.
