【摘要】 随着信息技术的发展和后PC时代的到来，嵌入式产品成为当今计算机产业的重要需求之一，同时巨大的嵌入式应用也对嵌入式设备提出了更高的要求。在掌上终端领域，为了支持视频播放等应用，要求掌上终端能够和主机进行数据通讯，能够从主机下载视频文件。正是在这一背景下，提出在掌上终端上实现USB海量存储功能，这样就很容易通过USB与PC进行数据通讯。本文首先详细分析了USB海量存储设备类规范(Universal Serial Bus Mass Storage Class Specification)及其相关协议，在移植uClinux到基于S3C4510B处理器的评估板，和编写相关驱动后，实现了USB存储盘，最后在USB存储盘上实现网络存储功能，即通过远程网络可以对USB存储盘进行读写。本文所研究实现的USB存储盘遵守USB1.1规范和USB Mass Storage协议的要求，通过USB与任何兼容此规范的主机相连后，该主机便可以把该USB存储盘当作本地磁盘来存取。本课题所实现的网络存储功能，意味着用户能够通过网络对USB存储盘进行读写，用户无需携带存储盘就能在远程对文件进行存取操作。更多还原

【Abstract】 With the fast development of information technology and the coming of post-PC era, the embedded product becomes one of the most important products of computer industry. Meanwhile, plenty of the embedded applications call for better performance and functionality. In handset field, to support application such as video playback, handset is required to be able to exchange data with PC, and download video file from PC. Under this background, it is put forward in this dissertion that handset should implement the function of USB mass storage, so that it can easily exchange data with PC through USB line.This dissertion first does a detailed research in the Universal Serial Bus Mass Storage Class Specification and its relevant protocols, after porting uClinux2.6 to evaluation board that base on processor S3C4510B, and designing relevant drivers for the system, the USB storage disk is made. Finally this dissertion implements network storage function on USB storage disk, which means one can read and write USB storage disk through remote network.The USB storage disk realized by this dissertion is compatible with USB1.1 protocol and USB Mass Storage protocol, after connect PC that is compatible with these protocols with USB line, the PC can read and write USB storage disk as its local disk. The network storage function realized by this dissertion, means that user will be able to read and write USB storage disk through network without having to carry it.更多还原
