Dynamic Scheduling of Real-Time Tasks in Heterogeneous Multicore Systems

摘要

The shift from homogeneous multicore to heterogeneous multicore introduces challenges in scheduling the tasks to the appropriate cores maintaining the time deadline. This letter studies the existing scheduling schemes in a heterogeneous multicore system and finds an approach to enhance the homogeneous system model to heterogeneous scheduling architecture. The proposed model increases the overall system utilization by accommodating almost all the tasks (low power task and high power task) into appropriate cores (big high power and small low power). It further enhances the system performance by allocating rejected jobs from small cores into the big cores through a dispatcher.
