摘要
针对我军现有电总线系统结构复杂、传输速率低、电磁兼容性差等问题,文中提出一种基于IEEE 1394b的光纤总线解决方案。文中介绍了基于IEEE 1394b的光纤总线结构,并对1394b的PCI总线接入、光纤总线接入以及光纤收发模块设计等关键技术进行了详细的研究。该总线由1394b协议实现总线管理,利用1394b对光纤接口的支持扩展光纤总线结构,通过PCI总线与微处理器连接,是新一代军用武器系统总线的发展方向之一。
To solve problems of our military system based on electrical bus,such as complex structure,low transmission rate,bad electromagnetic compatibility,this paper proposed a kind of optical fiber bus based on IEEE 1394b. The paper mainly introduced the structure of optical fiber bus based on IEEE 1394b and details related key technologies including 1394b-PCI access,1394b-optical fiber bus access and optical fiber transceiver.The optical fiber bus realizes bus management by 1394b protocol,expands the optical fiber bus by the optical interface support of 1394b,and connects with micro-processor by PCI bus.This kind of optical fiber bus will be the research focus of new-style military system bus.
