摘　　要：分析了开放式实时系统双层调度框架的调度特点,指出了其仅适用于硬实时环境的缺陷。在保证硬实时应用可调度性的基础上,针对硬实时和软实时应用的不同特点提出了一种改进方案,增加了软实时应用的处理,拓展了原方案的适用范围,完善了开放式实时系统的双层调度框架,最后用理论证明与仿真实验验证了改进方案的有效性。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.
