Embedded System

Course Description:

Embedded software is found in most electronic devices designed today. Embedded software controls our cell phones, microwaves, network routers, automobiles, and industrial controls. Each of these embedded systems is unique and highly customized to the specific application. As a result, embedded systems development is a widely varying field that can take years to master.

This course will cover some of the basic principles of writing software for embedded systems. The course will survey the issues and discusses the various techniques for dealing with them. In particular, the course discusses approaches to the appropriate use of the real-time operating systems upon which much embedded software is based. In addition to explaining what these systems do, this course provides guidance on how you can use them most effectively. The information in this course is not specific to any microprocessor or real-time operating system nor is it oriented towards any particular software design methodology. The principles are the same, regardless of which microprocessor and which real-time operating system and which software design methodology you use. We will concentrate on the principles that you can apply to almost any embedded system project.

The material in this course will provide the necessary information to understand the embedded systems development cycle and the specialized aspects of developing and testing software in this environment. This course will also discuss the design considerations unique to embedded systems. The course will cover the key methods and technologies for each phase of the development process: specification, partition, design, integration, validation, and maintenance and upgrade.
