This course is delivered in co-operation with Doulos' training partner Feabhas , who specialise in training courses for real-time embedded developers.

Course description

A two-day course providing an introduction to the theory, structure and practice of real-time operating systems. Particular emphasis is placed on issues related to embedded applications. Nevertheless this course is still of significant value to engineers developing non-embedded real-time projects. The course covers basic concepts, practical issues and commercial implementations of modern operating systems. Approximately 50% of the time is given over to lectures, the remainder being split between course workshops and practical demonstrations.

This course is ideal for engineers who are new to the field of realtime. It is also applicable to both managers and engineers who are considering the use of Real-Time Operating Systems on future projects.

The course has been developed by the well-known real-time author Dr. J. E. Cooling.

The course is available on-site and is also part of our public training schedule. We are always happy to discuss course customisation.

Overview

A two-day course providing an introduction to the theory, structure and practice of real-time operating systems.

Course Objectives

After completing the course attendees 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 RTOS facilities.
• Be competent to progress to vendor-specific detailed training.

Please note: This course does not set out to equip attendees with the skills, knowledge and expertise to design real-time operating systems or to program with a commercially available RTOS. To be able to program with a commercially available RTOS vendor specific training should be taken. This course is a suitable precursor to that vendor specific training.

Pre-requisites

• Knowledge of a high level language (e.g. Pascal, C, C++, etc.). Minimal expertise is required.
• An understanding of the fundamentals of computer-based systems.

Who should attend?

Application programmers, software engineers, support engineers or technical staff new to the field of Real-Time Operating Systems (RTOSs).

Materials

• Delegate handbook

Related courses

• Real-Time Software Design with UML 2.0
• C++ for Embedded Developers
• C for Real-Time Developers
• Developing for Embedded Linux
• Developing Linux Device Drivers

Course workshop

The course exercises are designed to foster an understanding of design patterns, object orientation, and C++. Ample opportunity is provided for delegates to consider the implications of patterns to the size and space concerns of embedded systems whilst reflecting on the broader quality issues that they directly address.
