Chen Qi · Dianli zidonghua shebei · 2001
As an important innovation of peripheral interface technology,USB introduces the network topology concept into traditional computer structure.With its facility for terminal user,wide applicability,dynamic bandwidth distribution,excellent error tolerance and higher cost performance ratio,USB simplifies the attachment of peripherals,meets the requirement of multimedia function expansion,and gradually becomes the main computer interface.After a brief introduction of the development motivation,technical targets and functional features,the hierarchical structure of USB is systematically summarized,including system overview,physical interface,power supply characteristics,bus protocol,performance of error tolerance,system configuration,data flow modes,host computer ,hardware software,etc.More details will be provided in the successive articles.
