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

功耗、散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对有效和高效的电源管理的需求，该项目研究了创建可感知电源的硬件和软件的统一方法。这部作品的一个关键基本理念是“实权”制度的概念。与实时计算机系统相类比，实时电力系统寻求以最佳性能保持可预测和可管理的功耗水平，而不是简单地降低功耗而不考虑性能。跨越操作系统、编译器和硬件的多层方法为仅在硬件级别上难以解决的问题带来了杠杆作用。

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.
