摘　　要：为了满足不同安全等级主机间单向数据传输的应用要求,介绍了一种基于EZ-USB FX2实现的单向传输系统设计方案,采用通用串行总线USB2.0芯片Cy7c68013和先入先出存储器IDT72v06,通过Cy7c68013通用可编程接口与外部先入先出的连接,实现了在不同安全域主机之间单向、高速、安全可靠的数据传输。To satisfy the application requirements for host-computers uni-directional data trans-mission in different security ratings, a design scheme of uni-directional transmission system based on EZ-USB FX2 is presented in this paper. And the system which adopts the Universal Serial Bus（USB）2.0 chip Cy7c68013 and IDT72v06 First in First out（FIFO） memory, realizes uni-directional, high-speed, safe and reliable data transmission between the host-computers in different security domains, with hardware design of external FIFO through General Programmable Interface（GPIF） and application program.
