摘　　要：介绍了一种高速实时数据采集系统的设计,该系统以F PGA作为逻辑控制的核心,以U SB作为与上位机数据传输的接口,内置一路A D转换,最高采样速率40 MHz,预留40针IDE接口,可以扩展各种不同的传感器与A D板,数据传输速度超过40 MB/s。给出了系统内部结构设计图,设计思路、实施过程、仿真结果和实验结果、固件(Firmware)和基于C#的应用程序开发,以期为各种传感器的调试与数据采集等提供有益的参考。The design of a high-speed real-time data acquisition system with the FPGA as a core logic control is introduced.The system has the following characteristics： using USB2.0 as data transfer interface to the host computer, building in an AD conversion, the maximum sampling rate 40 MHz, 40-pin IDE reserved for interface, expansion of a variety of sensors and AD board, and data transmission speed being over 40 MB/S. The internal structure design of the system, design ideas,implementation, simulation and experimental results, and the firmware and application based on C# are given for a variety of sensors to provide a useful reference for debugging and data acquisition.
