基于PCI9054的PCI高速通信接口实现

Implementation of PCI high-speed communications interface Based on the PCI9054

PCI总线是计算机的一种标准总线,具有即插即用、中断共享、高速传输等优点,因此得到了广泛应用,并且出现多个升级扩展版本,但电气协议复杂,开发难度大。本文利用PCI9054协议转换芯片,用VerilogHDL语言在FPGA中产生相应的控制信号,完成对数据的快速读写,从而实现与PCI总线的高速通讯。实验结果证明此方案工作稳定,传输速度快,数据准确,可扩展到其他需要通过PCI等总线系统中。

The PCI bus is a standard computer＇s bus, based on the advantages of plug-and-play, interrupt sharing and high-speed transmission,which has been widely applied in a number of upgrades and extended version, but the complexity of electrical agreement brings very great difficulties of the development. Using PCI9054 protocol conversion chips, with Verilog HDL in FPGA to produce the control signals, this programme achieves rapid reading and writing of data. Experimental results show that this programme works stabilly, transmission of data is speedy and accurately, which can be expanded to other needs, such as through the PCI bus rapid data transmission system .
