Real-time Multitask Scheduling for Underwater Vehicle Control System
Wei Liu · Tance yu kongzhi xuebao · 2002
In real time system, the run time of multitask is one of the key factors in selecting the algorithms. In this paper, the multitask system is modeled by using a task graph, and the run time and inter task precedence constraints are clearly described. An Incidence Matrix is presented to mathematically describe the relationship among tasks, and a search approach based on Incidence Matrix is given. Finally the underwater vehicle control system multitask schedule and the results are presented as an example.
