在许多实时应用中，系统中的任务集以及任务的特性在系统执行期间改变。具体地说，系统随着其使命的进展从一种执行模式移动到另一种执行模式。模式改变的特征在于删除某些任务、添加新任务或改变某些任务的参数，例如，增加采样率以获得更准确的结果。本文讨论了如何模式的变化，可以容纳在一个给定的优先级驱动的实时调度框架。
In many real-time applications, the set of tasks in the system, as well as the characteristics of the tasks, change during system execution. Specifically, the system moves from one mode of execution to another as its mission progresses. A mode change is characterized by the deletion of some tasks, addition of new tasks, or changes in the parameters of certain tasks, for example, increasing the sampling rate to obtain a more accurate result. This paper discusses how mode changes can be accommodated within a given framework of priority driven real-time scheduling.
