In a global scheduling strategy, all task instances are stored in a single queue and, at any given time, the processors run the instances with the highest priority.

全局调度的思想是系统中的所有任务的实例储存在一个队列中，在任何给定的时刻处理机运行具有最高优先级的任务的实例。

Under preemptive scheduling, the highest priority task executes until it enters the waiting or dead states or a higher priority task comes into existence.

采用抢先调度方式时，具有最高优先级的任务先执行直到它进入等待或僵死状态，或者是有更高优先级的任务产生。

In real-time control systems based on fixed priority scheduling, the latency and jitter of task are important factors which will impact the stability of the system.

在基于固定优先级调度实时控制系统中，任务的延迟与抖动是影响系统稳定性的重要因素。
