Adapting FTT-CAN for the joint dispatching of tasks and messages
Mário J.B. Calha, José Fonseca · 2003
In the context of centralized holistic scheduling of tasks and messages, dispatching can he an issue. This paper presents an architecture with a centralized dispatcher that can be easily integrated in any distributed control system without introducing significant overhead. A central node dispatches both tasks and messages to other nodes that are only required to possess a nano-kernel. Furthermore the interdependences between producer/consumer tasks and messages are studied, resulting in a set of constraints that guarantee system feasibility. It is also shown that this solution is easily implemented using a protocol for message dispatching such as FTT-CAN (flexible time-triggered communication on CAN).
