摘　　要：在介绍PCI9052主要功能的基础上,以具体PCI图像采集卡设计为例给出了技术上的实现 办法。采用旁路计算机系统内存,打破了记录系统的数据传输仅为二分之一PCI总线带宽的速度限制,有效地提高了PCI总线上设备之间的传输率。The technology solution is given by an example of a PCI Image sampling board design based on introducing the main functions of PCI9025. The speed limitation that the data transmission of the recording system is only equivalent to half that of PCI bus bandwidth has been broken by using a bypass computer internal memory. Thus the transmission rate between the various equipment of PCI bus has been effectively improved.
