摘　　要：基于FPGA和USB2.0的技术方案,设计了一种高速化和集成化的数据采集系统。该系统是以Altera公司的FPGA芯片EP2C5T144为主控芯片,以Cypress公司的EZ-USB FX2芯片为传输手段设计实现的。首先详细介绍了整体系统的框架结构和硬件接口电路,其次,在硬件平台完成的基础上采用Verilog HDL硬件描述语言设计完成了FPGA控制接口电路的代码,并设计完成了USB2.0的固件程序。最终通过软硬件系统联调完成了系统测试,该测试结果表明整个系统功能正确,能够完成一般情况下数据采集的任务需求。Based on FPGA and the USB2.0 technical, this paper designed one kind of high speed and integrated data acquisition system. This system took Ahera Corporation＇s EP2CST144 FPGA as the master controller, and took Cypress Corporation＇s EZ-USB FX2 as the transmission method. Firstly, integrated system＇s frame construction and the hardware interface circuit were introduced in detail. Secondly, based on the implement af hardware platform, interface code was designed by using Verilog HDL, and USB2.0 firmware program was designed. Finally, the system test was completed through software and hardware system. This test result indicates that the overall system function is correct, and it can accomplish the data acquisition duty under certain circumstances.
