Course Description

This course describes software-engineering techniques to develop software for embedded systems. This course examines requirements analysis, the definition of object structure and behaviour, architectural and mechanistic design, and more detailed designs that encompass data structure, operations, and exceptions. The object-based Unified Modeling Language (UML) is used to describe the structural and behavioral aspects critical to real-time systems

Course Objectives

To understand the principles of software design for resource constrained devices
To understand real-time/embedded software modelling with UML
To understand and apply real-time design patterns
