摘　　要：介绍了一种高速数据采集/重放系统。该系统采用工业控制计算机作为主控设备,在主控计算机内部配置了大容量内存作为高速海量存储介质。系统采用一块基于FPGA的高速信号采集/回放PCI卡来实现。该卡以FPGA为采集/回放的核心控制芯片,并在FPGA内部实现了64位/33MHz的PCI接口逻辑。系统有实时和非实时两种模式,其采集/回放速度高达240MHz,存储容量能扩展至3GB,它可供电磁信号环境仿真及复杂信号分析用。This paper refers to the implementation of high speed data acquisition/playback system . The system uses a computer based on industry control as the acquisition/playback control equipment, and uses the mass memory of the computer to store acquired data. The whole system uses a high speed signal acquisition PCI card based on FPGA to acquire data. The card uses FPGA as kernel chip to control the data acquisition/playback, and implemented the 64-bit/33 MHz PCI interface logic. The system has two work mode, real time mode and not read time mode. The acquisition/playback rate can reach up to 240 MHz, and the storage capacity can be extended to 3 GB. The system can be used in the simulation of radar signal processing and analysis of complicate signal.
