System-Level Approaches to Reducing Energy Consumption in Real-Time Embedded System Design

标题：实时嵌入式系统设计中降低能耗的系统级方法电源可管理的硬件设备对于降低系统能耗至关重要。为了最大限度地利用这些器件，必须开发新的创新方法来充分利用动态可调的功率与延迟特性。提出的研究旨在开发系统级技术，以降低由电源可管理的硬件资源组成的电池供电的实时嵌入式系统的能耗。该项目致力于获得对实时任务执行过程中电源可管理资源对性能和能耗的影响的基本理解。将考虑实际电源管理器件的非理想特性。主要活动包括i)为由电源可管理设备组成的系统设计高级分配和调度方案，ii)设计和分析可变电压处理器的电压调度算法，以及iii)在微架构级别开发预测硬件资源功耗/能量消耗的技术。培训学生为节能设计挑战做好准备也是该项目的一个主要组成部分，这将通过课程开发和本科生和研究生在研究中的积极参与来实现。

Hu, XiaoboCCR-0208992Title: System-Level Approaches to Reducing Energy Consumption in Real-Time Embedded System Design Power-manageable hardware devices are essential for reducing system energyconsumption. In order to benefit maximally from such devices, new and innovative approaches must be developed to fully exploit the dynamically adjustable power v.s. delay characteristics. The proposed research aims at developing techniques employed at the system level to reduce energy consumption in battery-powered real-time embedded systems composed of power-manageable hardware resources. This project strives to obtain a fundamental understanding on the effect of power-manageable resources on both performance and energy consumption during the execution of real-time tasks. Non-ideal features of real-world power-manageable devices will be considered. The major activities include i) devising high-level allocation and scheduling schemes for systems composed of power-manageable devices, ii) designing and analyzing voltage scheduling algorithms for variable-voltage processors, and iii) developing techniques to predict power/energy consumed by hardware resources at the micro-architectural level. Training students to prepare them for energy-conscious design challenges is also a major component of the project, which will be achieved through course development and active involvements of both undergraduate and graduate students in the research.
