摘要
为了实现光纤通道技术在机载计算机中的应用,介绍了光纤通道优点,说明基于PCI接口的光纤通道主机适配器的工作原理,分析了该适配器提供的邮箱命令和队列两种软件编程接口工作机制,给出嵌入式VxWorks环境下通信软件的实现方案。为开发机载光纤通道实时通信软件奠定了基础,对光纤通道嵌入式应用具有普遍意义。
The thesis is proposed to apply the FC(Fibre Channel)technology to the airborne computer systems. Firstly, the advantages of the FC technology are introduced. Secondly, the principle of FC host adapter based on PCI interface is described. Thirdly, two kinds of programming interface mechanisms of mailbox and queue are analyzed. Lastly, the implementation of communication software in VxWorks is provided. The result provides a basis for developing real-time communication software of FC technology in airborne system and is of prevalent significance in embedded application of FC technology.
