摘要
本文介绍嵌入式微处理器S3C2510的网络接口,并使用RTL8201芯片为之设计了硬件接口电路;设计实现了基于Nu-cleus操作系统的驱动程序,完成以太网控制器的初始化设置、收/发中断例程和利用缓冲链表数据结构向TCP/IP协议层交换数据。运行实测表明接口工作性能稳定可靠,满足网络流媒体数据处理的要求。
This paper introduces the network interface of S3C2510 embedded microprocessor, and the hardware circuit with RTL8201; the driver program based on Nucleus operating system is also designed, which includes Ethernet controller initializing, receiving/transmitting interrupt service routines, and data transferring to TCP/IP layer with buffer chains. Actual running test indicates the design is stable and reliable, and meets the requirement of network streaming media data processing.
