Introduction

An embedded system is a system designed to perform a dedicated function, typically with tight real-time constraints, limited size, low cost, and low power. It is a combination of computer hardware and software as well as additional mechanical, optical, or other parts typically used in the role of actuators, sensors, and transducers. In some cases, embedded systems are part of a larger system or product, e.g. an antilock breaking system in a car. Examples of embedded systems are cell phones, digital cameras, GPS receivers, fax machines, printers, debit/credit card readers, heart monitors, blood gas monitors [Gan03].
