摘要
针对PCI总线接口电路使用的广泛性,介绍了PLX公司桥接芯片PCI9054主模式的工作原理和中断机制,采用可编程逻辑器件FPGA实现与PCI9054的本地接口的信号转换,给出了逻辑实现方案和仿真图.介绍了WinDriver驱动开发工具,利用WinDriver工具,在WindowsXP系统下实现设备的驱动程序开发,完成主模式数据传输和设备中断的功能.
In this paper, the working principle and interruption mechanism were introduced for the initiator mode of bridge chip PCI9054 from PLX company in order to conform to the development trend of PCI interface. The signal conversion with local interface of PCI9054 was realized by the programmable logic chip FPGA. Furthermore, the logic program and simulation graphs were presented. The development tool of WinDriver was introduced whereby the driver program was developed for devices running on WindowsXP, completing the functions of data transfer in initiator mode and device interruption.
