Abstract: The Multi-core processors are requirement of recent needs. As the computers laptops and mobiles emerged with the need of high end computing as well as battery drainage problem it is much more necessary to work on scheduling. With the evolution of multiprocessors there is increase in battery consumption. Effective utilization of multi-cores of processors will ultimately enhance battery life. ARMís big. LITTLE architecture provides a way to efficiently schedule the tasks on the multiprocessors. This paper explores study on dynamic real time scheduling using Global task scheduling algorithms. This paper illustrates scheduling on current systems and various factors which contribute to the performance up gradation of the system.

Keywords: Multi-core processors, big. LITTLE, Real Time Systems.
