Module Duration : 20 Days

Objectives

The objectives of the course is to provide the students with an understanding of the aspects of the Real-time systems and Real-time Operating Systems and to provide an understanding of the techniques essential to the design and implementation of real-time embedded systems. This course covers two popular real time operation systems VxWorks and RTLinux.
