On completion, the learner will have experience in the architecture and the fundamental building blocks of a real time operating system.

Learning Outcomes

On completion of this module the learner will/should be able to;


Demonstrate a knowledge of the fundamental architecture and features of a modern real-time operating system. Describe the main issues addressed by RTOS implementation.


Describe and use the essential and optional functionality provided by an RTOS.


Design, implement and test application code that avails of RTOS services.


Demonstrate an understanding of and motivation for key RTOS service function implementations


Identify current day problems/key areas which are well-addressed by RTOS based solutions and evaluate a choosen application/implementation to determine how it makes use of RTOS features in meeting its purpose.

Teaching and Learning Strategies

Lectures/lab exercises

Module Assessment Strategies

Continuous Assessment

Written assessments during term                      

Practical assignments                                               

End of year exam                               

Repeat Assessments

This has a 60% final exam.  In the event of CA not been submitted for valid reason, the lecturer can at his/her discretion set repeat CA

Indicative Syllabus

Additional Information

As this is a niche subject in electronics, it would be proposed that a guest speaker or a study of a particular implementation of an RTOS in industry be undertaken to allow the learner to see how a company created and used an RTOS based system
