摘　　要：PCI总线对于不同机型具有很强的兼容性,介绍了一种基于PCI总线的4通道数据采集卡的设计方法。PCI总线规范的实现直接决定了模块设计的成功与否,所以重点介绍了PCI总线控制器PCI9030芯片的主要特点和内部结构,并给出了其内部结构框图和桥接电路,最后对数据采集系统的技术指标、系统结构和各部分功能作了简单介绍。PCI bus has a good compatibility of different types of computer, and this article introduces a design method of four-channel data acquisition module based on PCI bus. The success of design depends on the realization of PCI specification, therefore the paper emphasizes on the performance and architecture of the PCI controller PCI9030, and presents its interior structure frame and bridge circuit. And it also discusses the technique index, architecture and function of different parts of data acquisition system.

关 键 词：数据采集 PCI9030 PCI总线 FIFO
