| 摘 要： | 具有严格实时保障和安全保障的航空电子核心处理系统广泛采用分区管理技术,通过分层调度结构,满足任务时空隔离运行.通过将分区抢占行为看作是一个虚拟周期任务,针对下层调度器分别采用固定优先级和动态优先级两种调度策略,讨论了分区调度设计问题；利用分区任务调度的空闲时间构建分区调度保障条件,给出了满足任务可调度性的分区参数求解表...

| Abstract: | Partition management technology is widely adopted in core processors of avionic system with strict real-time and security guarantee ability.Through the hierarchical scheduling architecture,task executions can be isolated from time and space.The partition schedule design was discussed in this paper with focus on fixed-priority and dynamical-priority strategy by treating the preemptive behavior of partition as a virtual periodical task.The spare time in partition scheduling was used to construct the satisfied... |
