Computer Organization and Operating System

Course Objectives

The objectives of this course are:

• 1. To provide broad understanding of the requirements of Real Time Operating Systems.
• 2. To make the student understand, applications of these Real Time features using case studies.

Course Outcomes

Students will:

• 1. Be able to explain real-time concepts such as preemptive multitasking, task priorities, priority inversions, mutual exclusion, context switching, and synchronization, interrupt latency and response time, and semaphores.
• 2. Able describe how a real-time operating system kernel is implemented.
• 3. Explain how the real-time operating system implements time management.
• 4. Be able to work with real time operating systems like RT Linux, Vx Works, MicroC /OS-II, Tiny OS
