摘　　要：PCI9052是PLX公司推出的PCI总线接口芯片,能够实现ISA总线与PCI总线的无缝连接,可方便地将原有的ISA插卡移植到PCI总线。ADC-HS12B是DATEL公司生产的12位模数转换器,它采用CMOS工艺制造,可提供125Kb/s的采样率。该文在介绍CPCI总线的基础上利用FPGA技术控制ADC,实现模数转换数据采集方案。This paper studies the technology of data collection and processing system based on CPCI. The design mainly introduce two chips： one is the PCI9052 which can convert the is a bus to PCI bus. The other is ADC-HS 12B which is 12 bit resolution. The realization of design depends on the other elements, such as the control of the FPGA and the operational amplifier. This paper introduces one more effective way to realize AD conversion.
