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

嵌入式系统是通常不被识别为计算机的设备中的计算机，例如汽车、医疗设备和个人通信设备中的计算机。嵌入式系统的设计因其设计时间短、价格低、功耗低、高性能和可靠性等众多相互冲突的目标而变得复杂。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。该项目以嵌入式系统的自动分析、设计和控制为目标，致力于开发自动设计低功耗、低价格、高性能的嵌入式系统和集成电路的优化算法和软件。将实施一个快速和准确的分析和内存访问跟踪基础设施，用于对嵌入式应用程序和操作系统进行详细的电力和性能分析。节能操作系统调度和设备控制的理论将进一步发展，其结果将在新版本的广泛使用的嵌入式操作系统中得到体现和公开。嵌入式系统(专用计算机)使通信变得更容易，提高出行的速度和安全性，管理信息，并帮助人们完成数百项其他任务。这个项目使构建更好、更便宜的嵌入式系统成为可能。此外，在此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到学术研究中。

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.
