Abstract

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, e.g., increasing the sampling rate to obtain a more accurate result. This paper discusses a protocol for systematically accomplishing mode change in the context of a priority-driven preemptive scheduling environment.
