Abstract

The control structure of many real-time applications are naturally described by state machines. However the state transitions of these machines are governed not only by the state of the system and the occurrence of events, but also by their time of occurrence. The control structure of a real-time system determines what computation to perform and the set of timing constraints in effect at all times. The computation performed by the system can then be modeled by a directed graph, where the nodes denote transformations on the data and the edges denote data flow. In this paper we discuss some research issues that arise from the integration of control flow with data flow.<>

分布式硬实时系统中控制和数据流结构的集成
许多实时应用程序的控制结构自然地由状态机来描述。然而,这些机器的状态转换不仅受系统状态和事件发生的影响,还受事件发生时间的影响。实时系统的控制结构决定了在任何时候执行什么计算和有效的时间约束集。然后,系统执行的计算可以通过有向图建模,其中节点表示对数据的转换,边缘表示数据流。本文讨论了控制流与数据流集成中出现的一些研究问题。
