基于MPC8260的双100Mbit/s快速以太网的VxWorks驱动实现

Implementation of Double 100 Mbit/s Ethernets’Drivers Based on MPC8260 in VxWorks

介绍了基于MPC8260的FCC(快速通信控制器 )实现双 100Mbit/s快速以太网的简要原理,并结合ATM(异步传输模式 )综合交换系统的工程实现,介绍了硬件配置过程。在基于Vx Works嵌入式操作系统的BSP(板级支持包)的编写中,叙述了 100Mbit/s以太网驱动的实现流程,并简要给出了应用程序的调用入口方法。

MPC8260 is a MPU with powerful functions, which can deal with information powerfully and support high-speed communication modes such as ATM and fast Ethernet etc.. It has been widely applied inembed field. This paper gives in brief the principle of 1 0 0 Mbit / s Ethernet based on MPC 8260＇s FCCs.Basing on author＇s project of an ATM switching device, the paper gives the procedure of configuration of hardware equipments, and describes the implementation of 100 Mbit/s Ethernet＇s drivers for BSP programming.In the end, the paper gives the access method of the application programs.
