摘要：
Real-time heterogeneous systems are used widely in recent years. however, few algorithms were proposed to deal with integrated dynamic scheduling for hard and soft aperiodic algorithm is presented to dynamically schedule the task sets combining hard and soft real-time tasks in heterogeneous systems. The proposed algorithm tries to achieve a high scheduling success ratio for hard real-time tasks while guaranteeing the quality of service for soft real-time tasks as possible. Simulation results show that the scheduling success ratio of our algorithm is much higher than that of myopic algorithm, which is used as a baseline algorithm in simulations for a variety of task parameters.
