摘要
在Intel CPU计算机主板的板级支持包(board support package,BSP)基础上,对VxWorks操作系统的体系结构、嵌入式2.0标准的通用串行总线(universal serial bus,USB)系统、USB主机协议栈等方面进行了详细的分析,说明了USB主机协议栈各层之间的关系,阐明了VxWorks操作系统中USB驱动程序结构的特点和优点。为开发基于嵌入式计算机的USB驱动程序提供了可行的技术方案。
A number of factors including the architecture of the VxWorks operation system, the embedded universal serial bus （USB） system and the USB host stack, are analyzed base on the board support package （BSP） of computer mainboard installed an Intel CPU. We also discusse the relationship between every function level of USB host stack, and describe the characteristics of the structure of such USB driver. The method on the development of USB driver in an embedded computer system is proposed.
