高速U盘只读功能在S3C2410上的实现
he realization of read-only function for high speed U-Disk
为了降低"摆渡攻击"等木马病毒对个人计算机内信息造成的威胁，本文在以S3C2410为核心的嵌入式硬件平台上，利用高速USB接口芯片ISP1761，在未使用任何嵌入式操作系统的前提下，设计并实现了高速U盘只读功能。经过测试，本系统符合USB2.0高速标准，可识别市场上绝大多数U盘，并兼容FAT16、FAT32文件系统，同时能够正常操作大部分存储容量小于4G普通U盘，数据读出速率可达16Mbps。
he read-only function for high speed U-Disk was achieved under the embedded hardware platform by using no embedded OS, to reduce the threat of personal computer which was made by "Ferry Attack". The S3C2410 was used as the kernel CPU of the platform, and the ISP1761 was used as the interface chip to achieve the USB2.0 protocol. The standard of USB2.0 is agreed under test. Most U-Disk can be identified, and the file system is compatible with FAT16 and FAT32 also. The U-Disk which capacitance is less than 4G can be operated normally. The rate of data-reading is attained to 16Mbps.
