Timing Analysis in Multi-Core Real Time Systems

Abstract

The motive of using multicore processors in real time systems, is due to power requirement, processing speed and a heavy integration trend. Failing to meet the timing constraints in real time systems can lead to catastrophic results. So, every task in a real-time system has to be mapped and scheduled to meet the deadlines and utilize the system resources efficiently. Different measurable parameters, in each of the priority based scheduling mechanisms and type of application is identified. The simulation of varied time critical system is carried out for timing analysis using priority based approaches of task scheduling. The extensive experimentation of log uniform random task sets, indicates that there is a necessity of a multi objective task scheduling mechanism for real time systems. The partitioned approach of scheduling in priority based schedulers is desirable to achieve reliability in multicore real time systems.
