摘要： 嵌入式系统强调软硬件的协同性与整合性，软件与硬件可剪裁，以满足系统对功能、成本、体积和功耗等要求。文中通过对基于µC/OS-II操作系统的嵌入式系统驱动构件结构和驱动构件与微控制器(MCU)密切相关模块的分析，提出一种中间件技术来方便地裁减驱动构件的功能，提高驱动构件的复用性、可移植性。

Abstract: Embedded system emphasizes on its cooperation and integration of software and hardware. In order to satisfy the system need, it can 　be cut down in function, cost, size and power. This thesis analyses the structure of the drivers of embedded device which are based on µC/OS-II operating system and the modules of MCU which connect closely with the device. It shows a technology of intermediate module to realize the cutting down of drivers by the need, which increases reuse and transplant of drivers.

Key words: Embedded system, Intermediate module, µ, C/OS-II, Building block
