Review of Current Embedded System Hardware, OS, Development Systems and Application Domains for Instructional Design Abstract
Embedded computer systems are changing more than other computing environments since the scope of their application domain is expanding. Once embedded system development was largely focused on 8-bit, standalone systems written directly in assembly or C. These systems were characterized by slow CPUs and kilobytes of memory. Now they are embracing ever-widening application domains to include not only 8-bit standalone systems but real-time, networked, OS- based, wireless systems with megabytes of memory and 32-bit CPUs, with connections to the world through sensors, actuators and communication links.
In this burgeoning environment it is difficult for instructional designers to select a range of systems suitable for a college-level embedded systems course.
This paper reviews and classifies the application domains, hardware systems, operating systems and development systems for the field of embedded systems. This enables instructional designers to place specific systems in context and to intelligently select the appropriate sub-domain for their own purposes. Guidelines are proposed for courses in embedded systems for achieving different objectives.
Mark Weiser is regarded as the father of ubiquitous computing. His seminal articles describe a world where computers fade into the background and provide invaluable but invisible support for all the user wishes to do1, 2, 3. Using current technology this vision is pursued through embedded computer systems.
Embedded Systems (ES) are computer systems where the computer is subsumed in a larger system to perform functions in support of a larger goal. Usually an embedded system does not have a conventional Keyboard, Video (display screen) and Mouse (KVM). Systems are usually dedicated to performing a single task rather than running general purpose software packages. Some examples of embedded system applications include cell phones, car ignition and cruise control systems, media center remote controls, robots, digital cameras, cash registers, appliance controls, network routers, air-conditioning control systems and network switches. From this eclectic and abbreviated application list it is apparent that there is a very wide range of applications of embedded systems. The range includes hardware systems ranging from CPUs that operate at kilohertz to gigahertz, memory systems from hundreds of bytes to gigabytes. Despite this very wide range of application domains there are a number of common themes that run through these systems. The purpose of this study is to present classification categories for the different systems available. In so doing we recognize the scope of the task and suggest that this is merely one way to classify myriad systems and topics. The intent of this particular classification is to enable instructors to develop educational experiences for college students encompassing
