基于PCI Express的双路IEEE 1394b接口卡的设计与实现

摘要

The hardware platform based on dual⁃channel 1394b interface card with PCI Express architecture was developed with PLX's PEX8114. On this platform,the 1394b drive and the host PCIe interface drive based on Vxworks operating system are developed. The results of the testing and validation with the IEEE1394b data analyzer named FireSpy show that this two⁃channel 1394b interface can realize the real⁃time high⁃speed data transmission of 400 Mb/s,which proves that the system is fea⁃sible and realizable. It has a certain reference value for the design of other similar communication systems.%在此选用PLX公司的桥芯片PEX8114，设计并实现基于PCIe架构的双路1394b总线接口卡的硬件平台。在该平台上进行基于VxWorks操作系统的1349b驱动开发和主机PCIe接口驱动开发。经过与1394总线测试设备的验证测试，两路1394b总线接口可以实现400 Mb/s的高速数据实时传输，证明了该模块系统应用的可行性和可靠性，对其他通信系统的设计具有参考价值。
