基于NIOS II的嵌入式网络接口设计

Design of Embedded Network Interface based on NIOS II

阐述了基于N IOS II软核处理器和以太网控制芯片RTL 8019A S的网络接口设计。简要介绍了基于FPGA的SOPC(System On P rogramm ab le Ch ip,简称可编程片上系统)技术,给出了网络接口的软硬件的设计和实现。此设计增强了系统的灵活性,并且结构简单适应于不同应用领域对接入网络的需求。

This paper expounds the network interface design of NIOS II soft core processor and Ethernet RTI8019AS, and gives a simple introduction to FPGA - based SOPC technology, and designs and implements the network interfaces of software and hardware, which enhances the feasibility of the system and is adapted to the requirement of access network in different areas because of its simple structure.
