ITR: System Support for Energy Management in Mobile and Embedded Workloads

该项目的目标是开发一个集成的硬件/软件基础设施，以支持电池供电的移动和无线应用的电源管理。这些未来环境将支持具有苛刻要求的应用程序，例如灾难恢复。节能，特别是移动和嵌入式设备的节能，有望产生重大的经济、环境和社会影响。这些活动集中在三个关键方向：i)开发功率测量工具、工作负载和实验方法来评估能源消耗；ii)开发能源感知API以实现以应用为导向的电源管理；iii)开发系统支持高级解决方案。这些研究项目都依赖于评估想法的实验技术。对设备和工作负载特征进行经验测量和观察，找出最有潜力的问题领域。最初建立仿真模型缩小了解决方案空间，并允许考虑新的体系结构。最后，构建工作原型允许观察与真实操作环境相关的所有活动，并提供对其行为的更深层次的洞察。掌上电脑和掌上电脑平台的受欢迎程度和可获得性为这项研究提供了立即进行技术转移的巨大潜力。

The goal of this project is to develop an integratedhardware/software infrastructure to support power management forbattery-powered mobile and wireless applications. These futureenvironments will support applications with demanding requirementssuch as disaster recovery. Energy conservation, especially formobile and embedded devices, promises to have significant economic,environmental, and societal impacts.The activities focus on three key directions: i) the development ofpower measurement tools, workloads, and experimental methods toevaluate energy consumption, ii) the energy-aware APIs to allowapplication-directed power management, and iii) the development ofsystem support for high-level solutions.These research projects all rely on experimental techniques forevaluating ideas. Making empirical measurements and observations ondevice and workload characteristics pinpoints the problem areas ofgreatest potential. Initially formulating simulation models narrowsthe solution space and allows consideration of new architectures.Finally, constructing working prototypes allows observation of allactivity associated with real operating environments and offersdeeper insights into their behavior. The popularity andaccessibility of the palmtop and handheld platforms gives thisresearch significant potential for immediate technology transfer.
