21世纪计算机网络已经成为人们广泛使用的工具。通过计算机网络,人们可以进行网络控制、信息交换等。本文介绍一种基于NiosII处理器的嵌入式Web服务器的设计方法。系统在Cyclone系列1C20F400C7芯片上,采用软核处理器NiosII来配置核心处理器。NiosII核是用户可随时配置和构建的32位指令集和数据通道的嵌入式系统微处理器IP核,网络协议采用LWIP,这是一种专门针对嵌入式系统应用而设计的网络通信协议,接口芯片使用LAN9C111。本文基于NiosII的嵌入式Web服务器能够达到预期的效果,用户可以通过IE浏览器浏览存储在FLASH芯片中的网页,由于CPU本身是以软核的方式实现,其功能可根据需要进行定制,非常灵活。
The 21st century computer network has become a widely used tool. Through the computer network, people can carry out network control, information exchange and so on. This article describes a NiosII processor-based embedded Web server design. System Cyclone series 1C20F400C7 chip, using soft core processor NiosII to configure the core processor. The NiosII core is an embedded system microprocessor IP core that users can configure and construct 32-bit instruction sets and data channels at any time. The network protocol adopts LWIP, which is a network communication protocol specially designed for embedded system applications. The interface Chip using LAN9C111. This article based on NiosII embedded Web server to achieve the desired results, users can browse through the IE browser stored in the FLASH chip page, because the CPU itself is implemented as a soft-core, its function can be customized as needed, very flexible .
