摘要：嵌入式系统就是指以应用为中心、以计算机技术为基础、软件硬件可裁剪、适应应用系统对功能、可靠性、成本、体积、功耗严格要求的专用计算机系统，它将操作系统和功能软件集成于计算机硬件系统之中。本论文围绕LINUX嵌入式系统的可裁剪性，分析其作为开发板嵌入式系统应用时,针对硬件电路驱动程序的编写。以RedHat 5为开发环境，讨论和分析LINUX驱动体系结构的组成，着重分析硬件驱动程序加载进内核模块的过程以及内核模块与驱动程序冲突时，影响驱动程序兼容性的主要因素。

Abstract：The embedded system is used to refer to the center, computer technology as the foundation, the software and hardware can be cutting, adapt to the application system to the function, reliability and cost, volume, power consumption of the computer system for strict requirements, it will be operating system and software integration function in system of computer hardware. This paper around LINUX embedded system can cut sex, and analyzes its development board as embedded system application for the hardware circuit and the writing of the driver. In RedHat 5 for the development environment, discussion and analysis of the structure of driving system LINUX, focus on analyzing hardware driver loading into the kernel modules of the process and the kernel module and the driver conflict, the influence of the main factors driver compatibility.
