An embedded system is an application that contains at least one programmable computer (typically in the form of a microcontroller, a microprocessor or digital signal processor chip) and which is used by individuals who are, in the main, unaware that the system is computer-based. Use of embedded processors in passenger cars, mobile phones, medical equipment, aerospace systems and defence systems is widespread, and even everyday domestic appliances such as dishwashers, televisions, washing machines and video recorders now include at least one such device. This course provides a hardware-free introduction to embedded software for students who: Already know how to write software for desktop computer systems. Are familiar with a C-based language (Java, C++ or C). Want to learn how C is used in practical embedded systems.
