摘　　要：为了满足工程应用中高速信号采集的需求,文中设计并实现了一种光接口高速数据采集系统。该系统硬件部分以FPGA为核心完成光接口传输数据的接收,通过大容量DDR2实现对16位数据的缓存,以cPCI芯片作为数据采集板与上位机的交互的桥梁,由计算机应用程序进行控制,将采集到的数据PCI总线传回计算机中进行数据的存储以及时域、频域波形显示以及相关性能指标的计算。In order to meet the requirements of high-speed signal acquisition in engineering applications, this paper designs and implements an optical interface high-speed data acquisition system. The system used FPGA as the core to receive 16 bit data through optical interface and stored in high-capacity DDR2, The cPCI chip is the bridge of data acquisition board and PC, Computer application controls collected data back to the computer through PCI bus to achieve time domain, frequency domain waveform display as well as the calculation of the relevant performance indicators.
