ITR: Designing "Real-Power" Systems: Static and Dynamic Techniques for Managing Power/Performance Tradeoffs

功耗、热问题和电池寿命是许多计算机系统的主要设计问题。为了解决当前计算机系统中有效和高效的电源管理需求，本项目研究创建电源感知硬件和软件的统一方法。这项工作的一个关键基础哲学是“实权”系统的概念。与实时计算机系统类似，实时功率系统寻求在最佳性能下保持可预测和可管理的功耗水平，而不是不考虑性能而简单地降低功耗。跨越操作系统、编译器和硬件的多级方法可以有效地解决仅在硬件级别难以解决的问题。

Power consumption, thermal issues, and battery lifetimes are primary design issues in many computer systems. To address the needs for effective and efficient power management in current computer systems, this project studies unified methodologies for creating power-aware hardware and software. A key underlying philosophy in this work is the notion of "real-power" systems. Drawing an analogy to real-time computer systems, real-power systems seek to maintain predictable and manageable levels of power consumption with the best possible performance, rather than simply reducing power consumption regardless of performance. A multi-level approach spanning operating systems, compilers, and hardware brings leverage to a problem that is difficult to address at the hardware level alone.
