基于FPGA的1394b光纤总线接口设计

Interface Design of 1394b Optical Fibre Bus Based on FPGA

为解决1394b光纤总线在军用车辆领域应用过程中的设备兼容性问题,基于1394b异步传输机制,采用FPGA作为中心处理器完成1394b接口设计。并以实现PC机1394b接口与PC机串口之间通信为例,通过FPGA实现RS232接口连接PC机进行系统性能测试,实现1394b光纤总线与通用总线协议设备的兼容。结果表明,该设计对总线的扩展应用具有一定的作用。

In order to solve the compatibility problem of 1394b optical fibre bus＇s application in military vehicle, the 1394b＇s interface was realized which was based on 1394b＇s asynchronous transmission mode and used FPGA as center processor. The connection between RS232 and 1394b was designed to test the system, which accomplished the compatibility of 1394b and general bus protocol. Analysis shows that the design can accelerate 1394b＇s applications.
