About Embedded Systems

An embedded system is a specialized computing system designed to perform one or more dedicated functions within a larger electrical, electronic or mechanical system.

Unlike a general-purpose computer, an embedded system is developed for a specific task. It normally combines hardware, software, memory, input-output devices and communication interfaces. Embedded systems are used in appliances, vehicles, medical equipment, industrial machines, cameras, smartphones, communication devices and automation systems.

Why Study Embedded Systems?

Course Objectives

  1. To introduce students to the basic functions and applications of embedded systems.
  2. To introduce the architecture of embedded systems.
  3. To introduce various communication protocols.
  4. To provide knowledge of memory types and supporting technologies used in embedded systems.
  5. To provide knowledge about the development of embedded software.
