摘　　要：系统级动态功耗管理(Dynamic Power Management,DPM)策略根据系统状态和负载,动态地调整系统配置,从而能够有效降低系统功耗。传统的DPM策略仅从设备的角度考察工作负载状况,忽略了工作负载的应用特征。本文从任务的角度分析负载,提出新颖的多请求源(Multiple Service Requesters,MSR)系统级功耗管理的模型,以及基于该模型的自适应超时策略(Multiple-Service-Requester-Based Timeout Policy,MSRBTP)。实验表明,与传统DPM策略相比较,在非平稳的应用环境下,MSRBTP策略具有更好更稳定的节能效果。System-level dynamic power management （DPM） techniques observe the status and workload of the system, and dynamically reconfigure the system to reduce power consumption. Traditional DPM policies only focus on the device requests and neglect the application features behind the workload. In this paper, we establish a novel system-level DPM model： MSR （Multiple Service Requesters） DPM model, for the multi-task application environment. Based on the model, we put forward the MSRBTP （Multiple-Service-Requester-Based Timeout Policy）. As the simulation experiment shows, comparing with traditional DPM policies, MSRBTP is more stable and more efficient in the non-stationary application environment.
