本文转载至：http://rts.lab.asu.edu/web_438/CSE438_Main_page.htm

Thecourse provides the opportunities for students to learn various fundamentalissues as well as practical developments in the area of embedded systemsprogramming. After completing the course, students will be able to

1. Understand the design issues ofembedded software and gain an in-depth knowledge of development and executionenvironment on target processors.

2. Understand the functions and theinternal structure of device interfaces, drivers, and real-time operatingsystems.

3. Acquire the skill to developmulti-threaded embedded software in target environment, including good qualityand coding style for embedded programming, and testing and debugging approachesto verify embedded software operations.

4. Develop feasible task scheduling andcarry out system performance and task schedulabilityanalyses.

Aproper target development environment will be adopted for teaching and softwaredevelopment. An embedded platform, with rich architectural features, will beused to investigate embedded software characteristics, DMA and IO operations inhigh-speed data planes,
PCIe, and mmpdevices, and to experience system design and development practices.

Project:

Alldesign and development projects will be carried out in the real-time embeddedsystems laboratory which is located in the 2nd floor of Brickyard Building. The lab consists of PCs withLinux and Windows operating systems, and Eclipse IDE. The target
boards areIntel Atom mini-ITX boards.
