摘　　要：在嵌入式技术的设计与应用中,板级支持软件包BSP是嵌入式技术应用中软硬件结合层面的一个关键环节,其形式与作用随不同的软硬件环境产生的差异发生变化。如何为嵌入式操作系统"屏蔽"应用环境的差异是BSP的主要任务。从分析嵌入式技术定义、系统组成以及研发等几个方面,对BSP的作用及其关联环节进行分析,为嵌入式技术的应用提供帮助。BSP plays a key role which crosses the hardware and software for designing and application in the embedded technology, and its structure and functions are different as the system of software and hardware. How to shield these changes from the applications for the embedded operatiqn system is the main tasks of the BSP. On analyzing the definition of the embedded technology,the system structure and the designing products, that analyzed the functions of BSP which links with the otherj sections in the embedded system, so help us to use the embedded technology.
