摘　　要：1394B是一种高带宽、低延迟、高可靠特性高速串行总线,已经广泛应用于工业控制、汽车和航空航天等领域。文章设计了一种基于OHCI协议的1394B总线,主机通过PCI接口与1394B控制器之间通过DMA操作,实现数据的高速传输。1394B is a high-speed serial bus with high bandwidth, low latency and high reliability. It has been widely used in industrial control, car, aeronautics, astronautics and other fields. In this paper, a 1394B bus based on OHCI protocol is designed, which realizes the high-speed transmission of data through DMA operation between the PCI interface of the host computer and the 1394B controller.

关 键 词：1394B 开放式主机控制器接口 外围组件互连
