摘要
对嵌入式时操作系统(RTOS-Real-TimeOperatingSystem)的板极支持包(BSP-BoardSuppoPackage)PC操作系统中的BIOS进行了比较,分析讨论了BSP和设备驱动程序(Drivers)的关系,重点指出板级支持包是基于处理器类型,而设备驱动则是基于具体的操作系统,并结合WindRiver公司的实时操作系统VxWorks给出了编写BSP的具体流程.
In the paper,Board support package(BSP) of Embedded Real-Time Operating System is compared to BIOS of general PC.At the time,the paper analyzes the relationship between BSP and Driers,and it emphasizes that the base is type of CPU for BSP but a concrete Operating System for Drivers.Finally it gives a total flow of how to build a BSP,combined with VxWorks,RTOS of Wind River Company.
