摘要
一种基于VxWorks操作系统的实时通信模块,以PC104开发板为硬件平台,软件基于VxWorks实时操作系统。利用以太网、ISA总线等通信方式实现内部信号处理模块与外部其他模块的信息交互。着重介绍了实时多任务的设计流程,设计实现了ISA总线方式的数据通信和单点对多点的网络通信模式。
A real time communication data process module of which hardware is designed on PC104 and software is designed on VxWorks real time system . The module use Ethernet and ISA to communicate with other modules. The software flow of the real time multiple tasks working and analyses how to use ISA and how to communicate from one point to multiple point also are provided.
