| Abstract: | An improved two-level scheduling framework based on different characteristics of hard and soft real-time applications was proposed through analyzing the two-level scheduling framework in the open system. This improved approach can expand the application range through adding the process of dealing with soft real-time applications. The simulation results show its validity. |
