摘　　要：为满足电子测量数据采集系统的高速化和通用化要求,提出了一种基于PCI9054的PCI接口通用收发模块设计。结合PCI9054的物理架构和DMA突发模式工作原理,详细设计出该通用收发模块的核心组成部分,硬件采用PCI9054作为PCI桥接芯片,以Zynq系列FPGA(xc7z100ffg900-2)作为本地总线控制器。解析PCI9054上电配置方法,用FPGA搭建本地总线控制逻辑,对DMA突发读进行时序分析,突发速度可达100 MB/s。In order to meet the requirements of high speed and generalization in an electronic measurement data acquisition system,a universal transceiver module based on PCI9054 is proposed.In combination with the physical architecture and the DMA burst mode working principle of of PCI9054,the core components of this universal transceiver module are designed in detail.PCI9054 is adopted as PCI bridge chip and Zynq series FPGA(xc7z100ffg900-2)is selected as local bus controller.The power-on configuration method of PCI9054 is analyzed and the local bus control logic is built with FPGA.The timing sequence of DMA burst read is analyzed and the burst speed can reach 100 MB/s.
