Energy is becoming the limiting resource for many applications, as processor performance and network bandwidth continue to rapidly advance. Devices such as wireless sensor networks, cell phones with integrated personal organizers (PDAs), laptops, and even Internet hosting centers are all concerned about power consumption either due to limited battery capacity or the high cost of operating and cooling large server farms. In many of these systems main memory can become a significant portion of the overall power budget, particularly with the advent of low-power, high-performance processors.This project investigates main memory power management research issues that span several levels of computer system design: from the operating system managing memory power states, to the design characteristics of platform architectures, and finally down to the details of internal DRAM organization.This project will investigate power management design decisions within each system level and explore interactions across levels.

随着处理器性能和网络带宽的持续快速提升，能源正成为许多应用程序的有限资源。无线传感器网络、具有集成个人管理器(PDA)的手机、笔记本电脑，甚至互联网托管中心等设备都担心功耗，要么是因为电池容量有限，要么是因为大型服务器群的运营和冷却成本很高。在许多这样的系统中，特别是随着低功耗、高性能处理器的出现，主存可能成为总功率预算的重要部分。本项目研究了跨越计算机系统设计的几个层次的主存电源管理研究问题：从管理内存电源状态的操作系统，到平台架构的设计特征，最后到内部DRAM组织的细节。本项目将调查每个系统级别内的电源管理设计决策，并探索跨级别的交互。
