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.
The faculty for this course has extensive experience with a number of major realtime operating systems (RTOSs), including VRTX, pSOS, VxWorks, OSEK / VDX, Nucleus, OSE, μC/OS and others *. Instructors 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. 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

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.
