| Abstract: | For its simpleness and common-use, USB interface becomes the first choice of consume connect protocol. However,with the fast development of multimedia technique, the U SB2.0 couldn＇t now meet the requirement in high-speed application. With its 5Gbps transmission speed and backward compatibility,USB3.0 becomes the standard of next -generation high-speed connection. In accordance with the framework of USB＇s protocol,the USB3. O＇s data transmission protocol is analyzed from physical layer, link layer, protocol layer and frame layer, and also compared with the USB2.0 protocol. Finally,the realization of USB3.0 encrypted USB disk based on EZ-USB FX3is described. |
