摘要: 数据流语言是面向虚拟仪器的可视化编程环境的核心. 为了使这些基于数据流的编程环境能够应用到实时系统设计中,必须引^一种严格定义的实时文法.RTL文法适台描述数据流语言,但是异步节点的表述同题以及时间基准选择阃题并来解决.提出了一种用于描述单率、异步数据流语言的RTL文法.该文法中引入传输事件常量与状态谓词(state predicates)解决了异步节点的RTI 文法描述问题.
关键词: 虚拟仪器数据流语言可视化编程实时系统实时逻辑    
Abstract: Dataflow language (DFL)is the basis of most virtual instrument oriented visual pro-gramming environment.In order to apply these dataflow—based tools in real-time systems,a well defined real—time semantics must be provided.Though RTL semantics can be used to describe dataflow language,some issues such as the depiction of the asynchronous node and the selection of time scale still have not been solved.A RTL formal depiction of single—rate asynchronous dataflow language is presented.W ith bringing in the state predicates and transition event constants,the key problem of how to depict the asynchronous node can be resolved.
Key words: virtual instrument    dataflow language(DFL)    visual programming    real-time system    real—time log[c(RTL)
