板级支持包BSP是嵌入式系统中常用的硬件抽象形式,是介于操作系统和硬件之间的软件层次。介绍BSP的功能和特点,并结合工作实践提出了设计BSP的一般方法;最后针对当前嵌入式系统中BSP的设计方法所面临的问题提出了可行的解决办法。
Board Support Package BSP is a commonly used form of hardware abstraction in embedded systems. It is a software hierarchy that lies between the operating system and the hardware. Introduced the function and characteristic of BSP, and put forward the general method of designing BSP according to the working practice. Finally, a feasible solution to the problem of BSP in current embedded system is put forward.
