Subject specific learning outcomes and competences

Theoretical background and practical knowledge of real-time operating systems. After completing the course students will appreciate the use of multitasking techniques in real-time systems, understand the fundamental concepts of real-time operating systems, understand the features and structures of practical implementations, appreciate how application areas (e.g. safety-critical, desktop, etc.) impact on real-time operating system facilities.

Advanced knowledge of real-time operating systems.

Learning objectives

The primary goal of this course is to meet the participant with basics of real-time operating systems and to give the participant knowledge and skills necessary to develop software for embedded computer systems using a real-time operating system. 

Prerequisite knowledge and skills

Knowledge of operating system (OS) basics: overview of OS architectures, OS classification, UNIX core knowledge, OS service call principles, shell. Context switching, multitasking. File systems, processes, virtual memory. C-programming knowledge.
