通用串行总线数据传输模型

Data Transfer Models of Universal Serial Bus

通用串行总线 (U SB)是一种新型串行总线技术。本文首先简单介绍了 USB系统结构 ,然后较为详细地描述了 USB数据包格式。并针对 4种数据传输类型 (控制、批量、等时、中断传输 )分析了他们的数据传输模型。

The Universal Serial Bus(USB) is a new technology of serial bus Firstly give a brief introduction to USB architecture,and then a detailed description of the USB packet formats We also analyse the data transfer models about four different transfer types(control, bulk, isochronous,interrupt,transfers)
