摘要
介绍了基于FPGA和USB2.0接口的高速数据采集系统的设计。采用现场可编程门阵列(FPGA)为控制芯片,以USB2.0为接口实现FPGA和PC机之间的高速数据传输。通过软、硬件技术的结合,实现了对多路模拟信号及数字逻辑信号的采集,并介绍了固件(Firware)和USB设备驱动软件的开发。
The paper introduces the using of FPGA and USB in the design of VI system based on data acquisition system.In the system,we use FPGA as control core.USB2.0 is used for interface to realize the fast data transmission between the FPGA and the PC.Through the combination of soft and hardware,a multichannel analogy signal and digital logic signal acquisition system are implemented.In addition,firware and USB device drive are also introduced.
