COURSE OVERVIEW

This course introduces the principles shared by many real-time operating systems, and their use in the development
of embedded multitasking application software.

The course begins with the fundamental elements of real-time multitasking embedded application software design
and development.  Processor and operating system concepts relevant to multitasking systems are examined, with
focus on preemptive task scheduling, intertask communication and synchronization.

The course continues with a detailed survey of popular operating system kernel services, giving many application
examples.  Topics include timer services, dynamic memory allocation schemes, network communication
programming interfaces and device driver supervisors.  Multitasking code development is discussed and example
programs are reviewed and debugged.  Practical experience is gained during student work exercises.

On the third day of this course, advanced topics are discussed such as operating systems and hypervisors for
symmetric and asymmetric multiprocessing which are appropriate for multi-core SOCs.

The faculty for this course has extensive experience with a number of major real-time operating systems (RTOSs),
including VxWorks, OSEK / VDX, Nucleus, OSE, μC/OS, FreeRTOS, eCos, pSOS  and others *.  Instructor can provide
in-depth insight into the specific workings of these RTOSs during the course, if it is of particular interest.


WHO SHOULD ATTEND ?

This course is intended for practicing embedded systems software development engineers, software system
architects, project managers and technical consultants who are responsible for designing and implementing the
software for real-time and embedded computer systems using a real-time operating system.

Course participants are expected to be knowledgeable in the C programming language.

This is a course for engineers in industry with less than 3 years of experience with real-time operating systems.  [For
those with more experience, we recommend the advanced course "
Architectural Design of Real-Time Software"  .]


COURSE OBJECTIVES

The primary goal of this course is to give the participant the skills necessary to develop software for embedded
computer systems using a real-time operating system.  This is a very practical, results-oriented course that will
provide knowledge and skills that can be applied immediately.
