Jie Liu, S. Jefferson, E.A. Lee
2001 Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148)  
In complex applications, it is desirable to use different models in different parts of the system or under different modes of operation.  ...  This paper reviews run-time computation models for this kind of real-time embedded software, from message semantics, message acquisition, and the dataflow/control flow perspectives.  ...  For example, a priority-driven multitasking director will manage the priorities of actors and an event queue that dispatches events according to their destination actor's priority.  ...
