英文摘要：

This paper introduced the design of the data sampling system based on FPGA and USB2.0. The system used FPGA as the control core, which controlled USB chip, the process of data transfer, Flash memory and additional circuit module. The pa- per introduced the system structure, discussed the design methods of the hardware circuit and ahalyzed the software＇s working pro- cedure. It is proved that this system can accomplish the achieving and disposal of the real-time data. It is a strong universality data sampling system.
