Abstract

Operating systems play an increasing role in embedded computing systems, thanks to advanced applications. The real-time operating systems used in many embedded systems provide real-time sched- uling, make efficient use of memory, and often operate at low power levels. This paper describes our approach to teaching operat- ing system concepts in an embedded computing course, including some important aspects of embedded operating systems as well as lectures and labs we developed using Windows CE as an example embedded operating system.

1 Introduction Embedded computing systems must often perform multiple complex tasks that require the media- tion of an operating system. Operating systems are complex objects that programmers and system designers rely on to perform many functions. When designing embedded systems, the operating system plays a somewhat different role and system designers expect their operating systems to have particular attributes that may not be relevant to general-purpose programmers. We are inter- ested in the function of the operating system, its internal mechanisms, the resulting performance, and power consumption of the operating system. Programmers on general-purpose platforms tend to view the operating system as a set of services for application developers. Embedded system designers tend to view their operating systems as components with particular properties. Because embedded computing systems increasingly rely on real-time operating systems (RTOSs), students interested in embedded computing should have a basic understanding of embedded operating system concepts. Because the requirements and design of RTOSs is substantially different from that of general-purpose operating systems, tradi- tional operating systems classes typically do not cover some material that is of great importance to embedded system designers.
