摘　　要：文章以SHDSL嵌入式通信设备开发为例,阐述了在Linux中网络设备驱动的基本设计思想。详细介绍了利用MPC850DE中的SCC控制器实现HDLC通信模块的开发过程,并用动态加载到Linux内核的方式,实现系统的优化。其中HDLC通道为以太网和信令网之间提供数据链路支持,是该设备嵌入式系统开发的关键。Base on the development of the SHDSL embedded communication equipment as an example, the paper stated the basic design conception of the driving of the network equipment in Linux. The paper in detail introduced the development process of the HDLC communication module with the SCC controller in MPC850DE. The optimization of the system was realized with the dynamic load into the Linux core mode. The HDLC channel to provide the data link circuit support between the Ethernet and signaling network would be the key of the embedded type system development for the equipment.
