摘　　要：介绍了嵌入式Power PC处理器MPC8270的体系架构和多通道控制器(MCC)的工作原理。MPC8270具有4个TDM接口,每个TDM均支持E1/T1接口。MCC是MPC8270中重要的通信处理器模块,通过MCC可以根据需要很方便地进行时分复用数据的复用和解复用。基于Vx Works和MPC8270嵌入式系统开发平台,详细介绍MCC驱动程序的设计实现过程,描述了MCC的初始化、中断处理以及数据发送、数据接收处理等关键技术。该驱动设计具有实用性。The architecture of embedded processor MPC8270 and the basic working principle of Multi-Channel Controller （MCC） are introduced. MPC8270 has four TDM interface, and each TDM interface supports E1/T1 interfaces. MCC is an important communication processing module in MPC8270, and it is simple to multiplex and de-multiplex by MCC. Based on VxWorks operating system and MPC8270, the driver design and implementing processes of MCC are introduced in detail, which include initialization, interrupt processing, data receiving/sending processing of MCC. The driver design method is valuable.
