摘　　要：本文介绍了CYPRESS公司的EZ-USBFX2芯片的系统结构及其特点,并利用该芯片设计了基于USB2.0协议的高速数据采集系统。在系统软件开发过程中,首先阐述了固件程序的基本结构及设计,然后通过对现有的驱动程序进行优化,并在应用程序中采用数据的多线程预处理,从而提高了数据传输和系统运行的速度。实验结果表明,该软件系统是切实可行的。In this paper, the structure and characteristics of EZ-USB FX2 produced by Cypress Company are introduced, and a High Speed Data Collection System based on USB2.0 protocol with the chip is developed. In the procedure of the system development, the structure and design of firmware is expounded firstly. Then the driver is optimized and multithread pre-processing is used to improve the speed of data transmission and system processing. Experiments show that the system software is feasible and effective.
