摘　　要：随着网络技术的发展,网络接口设备的研究成为了当前研究的热门课题,嵌入式的数据处理平台在小型化、低功耗、低成本等方面表现出色。基于Altera公司推出的NIOS软核,移植μC/OS-II实时操作系统后,以其低成本、低功耗、强实时性为主要特点开发了嵌入式处理平台。通过Avalon总线接口完成了CPU与网络接口芯片LXT971A之间的数据连接,并在NIOS内部实现了网络数据的处理,完成了网络接口。With the fast development of network,the research on network interface equipment becomes a hot spot. The embedded data processing platform features miniaturization, low power consumption, low cost, Based on NIOS epu designed by Ahera and μC/OS-II operating system,the embedded processing platform is developed with main characteristics such low cost,low power consumption and high reahime performance. The data exchange between CPU and LXT971A is realized through Avalon bus interface, and the network data processing in NIOS and network interface are realized.
