Real Time Systems

Real Time Systems focus on the "logical" design of computing environments where the "technical" correctness depends not only on the result but also on the specific time it is delivered. These systems utilize "circuit-based technical materials" to ensure deterministic behavior for mission-critical tasks in hardware and "Communication Systems".

This course familiarizes students with different concepts of real time systems mainly focusing on scheduling, access control, memory management, optimization, and real time communications.

The main objective of this course is to provide core knowledge of different concepts of real time system which will enhance the student capacity in building real time systems.

The laboratory work should focus on implementation of concepts related to scheduling, memory management, synchronization and optimization using suitable simulators and programming languages. There should also be a case study.
