Abstract: A scheduler plays a major role in scheduling a task in multicore processor which will improve the performance by efficiently utilising the resources of each core. A heterogeneous multicore processor contains cores with different capabilities. The main objective of this work is to implement fuzzy logic-based efficient task scheduling scheme for the non-periodic tasks on soft real time heterogeneous multicore processor. Two fuzzy logic-based scheduling schemes namely dynamic priority generator (DPG) and efficient task scheduling scheme (ETSS) is proposed. Simulink model was designed for different test cases to measure the performance of the proposed system. Results shows that CPU utilisation of core 2 is 56.7% for the first set of membership function and core 3 is 49.4% for the second set of membership function among the heterogeneous quad core.

Keywords: heterogeneous; multicore processor; fuzzy inference system; task scheduling; membership function.
