Abstract :
The number and complexity of real-time functions in light and small airsystem´s (<;25kg) mission systems is steadily increasing. To provide the necessary computational power in a space-restricted environment, Multi-Core processors are used. Today, these Multi-Core processors are statically configured. To utilize the full potential of Multi-Core processors, the step towards dynamically reconfigurable phase-driven Multi-Core configurations has to be taken. In this paper, we will propose an opportunity for reconfigurable phase-driven real-time Multi-Core scheduling resting upon a knowledgebase. Especially we will illustrate the parameters for phase driven real-time tasks, the separation of function sets with mixed real-time requirements during operation, the feasibility and schedulability tests and mainly the creation algorithm of the Knowledgebase.
