摘要:基于FPGA的U盘数据交换器的设计,主要是利用FPGA(Field Programmable Gate Array)现场可编程逻辑门阵列芯片+USB-Host接口芯片取代计算机对U盘直接进行读写操作,即设计一个装置用于实现两个U盘直接的数据交换,而不是通过电脑实现,FPGA是整个系统的主控制器,也是整个系统的核心。此技术主要是通过FPGA+USB-Host芯片对USB-Host技术的实现,FAT文件系统规范的实现,大容量存储协议的实现以及USB实时传输方式的实现。

Abstract:The data transimiter based on FPGA for U-DISK is made up from the FPGA and the USB-HOST chip, It will read and write directly in the U-DISK instead of the computer, FPGA is the master controller of the whole system,it is also the core of the system.This is achived through the technique of USB 2.0 ,The technique includes the regulation of FAT Document System, the protocol of high storage and the method of simultaneously transmiting for USB
