Abstract

Embedded real-time systems are increasing day by day to execute high-performance-oriented applications on multicore architecture. Efficient task scheduling in these systems are very necessary so that majority of the tasks can be scheduled within their deadline and thus providing the needed throughput. This paper presents a scheduling algorithm where random tasks generated at different time intervals with different periodicity and execution time can be accommodated into a system, which is already running a set of tasks, meeting the deadline criteria of the tasks. The idle time of the cores has been found based on the execution time of the existing tasks. Using the concept of Pfair scheduling, random new tasks have been divided to fit into the idle times of the different cores of the system. We verify the proposed algorithm using generated task sets, and the results show that our algorithm performs excellently in all the cases.
