摘要
基于嵌入式emded实时操作系统rtos的要求,分析了VxW orks的功能,强调BSP(Board Support Package)针对于不同的基本接口界面,提供不同的BSP;同时说明BSP的功能是提供给操作系统一个无关的设备接口,可以让程序开发者在不熟悉具体硬件的情况下正确地配置硬件寄存器,给出了它的主要设计方法和实现过程。
Basing on the requirement of the emded RTOS, we analyse the function of VxWorks and emphasize the flexibility of BSP in correspond with the different basic connection interface. Simultaneously, BSP is functioned to supply a irrespective equipment connection so that the prpgram developer can collocate the hardware register correctly with no need to kown the specific hardware. Meanwhile, the major designing methord of BSP and the process of its realization are also introduced here.
