Energy-Aware Synthesis of Embedded Systems on Multiprocessor Platforms

项目概要：多处理器平台上嵌入式系统的节能综合。安德森在实时嵌入式系统领域的两个明显的趋势是（i）多处理器平台的扩散，和（ii）的应用程序的扩散，能源消耗必须被最小化。 在未来的几年里，我们有理由期待这两种趋势的融合：事实上，多处理器实现比单处理器实现的一个主要优势是前者往往更节能。 然而，到目前为止，在能量感知多处理器设计方面所做的工作很少，仅限于相对简单的表驱动调度方案;通过转向多处理器实现所实现的能量节省的精确特征尚不清楚。这些观察结果表明，在设计能量感知多处理器系统时，需要对存在的权衡进行研究。 本项目旨在通过开发和实验评估设计方法和调度算法来满足这一需求，这些设计方法和调度算法有助于在多处理器平台上合成嵌入式实时系统，其主要目标是最大限度地减少能耗。 部分基于这个项目的结果，将开发两个新的课程：嵌入式系统的介绍性研究生课程，和多处理器嵌入式设计的研究生研讨会。 嵌入式系统入门课程将阿萨当前实时系统和高级操作系统课程的后续课程。 关于多处理器设计的讨论课程是介绍课程的后续课程。 我们将共同努力，让代表性不足的群体参与我们的研究。 算法研究的结果将通过出版物传播。任何从这个项目中产生的通用软件将在网络上免费提供。

Project Summary: Energy-aware Synthesis of Embedded Systems onMultiprocessor Platforms Sanjoy Baruah James H. AndersonTwo evident trends in the real-time embedded systems domain are (i)the proliferation of multiprocessor platforms, and (ii) theproliferation of applications for which energy consumption must beminimized. In the years ahead, it is reasonable to expect these twotrends to converge: indeed, one major advantage of multiprocessorimplementations over uniprocessor ones is that the former tend to bemore energy-efficient. To date, however, the little work that hasbeen done on energy-aware multiprocessor designs has been limited torelatively simple table-driven scheduling schemes; a precisecharacterization of the energy savings realized by moving to amultiprocessor implementation is not known.These observations point to a significant need for research to beconducted on the tradeoffs that exist when designing energy-awaremultiprocessor systems. This project proposes to fill this need bydeveloping and experimentally evaluating design methodologies andscheduling algorithms that facilitate the synthesis of embeddedreal-time systems upon multiprocessor platforms, with the primary goalof minimizing energy consumption.Broader impact. Based partially on the results of this project, twonew courses will be developed: an introductory graduate course onembedded systems, and a graduate seminar on multiprocessor embeddeddesigns. The introductory embedded-systems course will be created asa follow-on to current real-time systems and advanced operatingsystems courses. The seminar course on multiprocessor designs will bea follow-on to the introductory course. A concerted effort will bemade to involve underrepresented groups in our research. Results fromthe algorithmic research will be disseminated through publications.Any software of general utility that results from this project will bemade publically available on the web.
