嵌入式实时调度框架研究

嵌入式实时操作系统环境中的多类型实时任务并存的情况给实时调度机制带来了新的需求和挑战。提出了一种适用于嵌入式实时环境的调度框架，可以调度多类型实时和非实时任务，且可通过自适应控制来调节软实时任务带宽，使系统实时性最优化。它引入了两个层次的任务准入控制，解决了任务相关性和资源等约束问题，保证了进入系统的任务独立性和可调度性。它具有良好的可扩展性和可配置性，适用于分布式实时环境。

Research on Embedded Real-time System Scheduling Framework

This paper proposes a new schedule framework for open real-time system.To adapt to change in open real-time system,the adaptive control tries to adjust the bandwidth of soft real-time tasks to get a satisfactory of soft performance.Taking relative tasks and resource constraints into account,this paper introduce a two-layers admission control to ensure tasks independent and system schedulability.With the feature of good scalability and configurability,the framework is suitable for open real-time system,and it easily extends to distribute multi-processors systems.
