摘　　要：随着外围设备的多样化和大量数据传输的需要,USB接口应用范围越来越广泛。介绍EZ-USB FX2接口在诱发电位仪系统中的应用。首先给出了整个诱发电位仪的总体设计,讨论了FPGA作为主芯片与EZ-USB FX2的硬件连接,在此基础上重点论述了基于Slave FIFO模式的EZ-USB FX2接口设计及相应固件程序开发。该应用实现了大脑诱发电位仪传输的高可靠性、高速化、小型化,具有良好的市场前景。With the diversity of peripheral equipments and the need of large amounts of data transfers, USB interface is more and more widely used. This paper introduced the application of EZ-USB FX2 interface in evoked potential system. Firstly, the paper provides the design of the integral system, and then discusses the connection between EZ-USB FX2 hardware and the main chip FPGA. On that basis, the paper emphasizes on the design of EZ-USB FX2 interface based on Slave FIFO mode and the relevant development of firmware program. The application of EZ-USB FX2 interface in brain evoked potential system introduced in this paper possesses the advantages of high reliability, high speed and small size, which might have a favorable market prospect.
