CAREER: Analysis, Design, and Synthesis of High-Performance, Low-Power, Real-Time Embedded Systems

嵌入式系统是通常不被认为是计算机的设备内的计算机，例如，汽车内的计算机、医疗设备和个人通信设备。 嵌入式系统的设计因其众多相互冲突的目标而变得复杂，例如，设计时间短、价格低、功耗低、性能高、可靠性高。 手动设计满足所有这些目标的嵌入式系统是一项艰巨的任务。 本项目以嵌入式系统的自动化分析、设计、控制为研究对象，开发低功耗、低价格、高性能的嵌入式系统和集成电路的自动化设计的优化算法和软件。 将实施一个快速准确的分析和基于内存访问跟踪的基础设施，用于详细分析嵌入式应用程序和操作系统的功耗和性能。 嵌入式操作系统（专用计算机）使通信、提高旅行速度和安全性、管理信息以及协助人们完成数百项其他任务变得更加容易。 该项目使构建更好、更便宜的嵌入式系统成为可能。 此外，该项目中开发的软件作为参考实现公开发布，以提高运行开源操作系统的嵌入式系统的电池寿命。 该项目与西北大学的嵌入式系统设计和实时系统课程相结合。 通过它，本科生受益于，并积极参与，学术研究。

Embedded systems are computers within devices that are not generally recognized as computers, e.g., computers within automobiles, medical devices, and personal communication devices. The design of embedded systems is complicated by their numerous conflicting objectives, e.g., short design time, low price, low power consumption, high performance, and reliability. Manually designing embedded systems that meet all these goals is an arduous task. This project targets the automatic analysis, design, and control of embedded systems.This project is developing optimization algorithms and software that automatically designs low-power, low-price, high-performance embedded systems and integrated circuits. A fast and accurate profiling and memory access tracing based infrastructure for detailed power and performance analysis of embedded applications and operating systems will be implemented. The theory for power-aware operating system scheduling and device control will be further developed and the results embodied and made public in a new version of a widely used embedded operating system.Embedded systems (special-purpose computers) make it easier to communicate, improve the speed and safety of travel, manage information, and assist people with hundreds of other tasks. This project is making it possible to build better and less expensive embedded systems. In addition, software developed in this project is publicly released as a reference implementation to improve the battery lifespan of embedded systems that run open-source operating systems. This project is integrated with Northwestern University courses on embedded system design and real-time systems. Through it, undergraduate students are benefiting from, and actively participating in, academic research.
