摘要
根据航天测控系统中各信号处理单元之间的流水性特征,提出了一种适用于软件化航天测控系统的驱动机制.文中首先介绍了软件化航天测控系统的基本结构,在研究了静态和动态数据流驱动机制的基础上详细论述了此种数据流驱动机制的设计与实现过程.它采用消息控制的方法,按照动态数据流驱动机制,实现各信号处理单元的进程间和每个信号处理单元内部的线程间的数据流驱动.同一般的动态数据流驱动机制相比,此种驱动机制具有灵活性和易于实现的优点.
The characteristics of the aerospace TT＆C signal processing is pipelining among diversified signal processing units. Based on the characteristics, a dataflow-driven mechanism for software-oriented aerospace TT＆C systems is presented. First, the basic architecture of the software-oriented aerospace TT＆C System is introduced. Then, based upon analysis of the static and dynamic dataflow-dnven mechanism, the design and implementation of this dataflow-driven mechanism is discussed in detail. It makes use of the message control mechanism and dynamic dataflow-driven mechanism and realizes dataflow-driven mechanism between signal processing units and between threads in every signal processing unit. Comnared with dynamic dataflow mechanism, this type of mechanism is flexible and easy to implement.
