摘要
介绍基于以太网的远程升级嵌入式系统的设计。硬件主要采用系统级芯片C8051F020单片机及RTL8019AS网络芯片设计,软件采用Keil Cx51单片机高级语言编程,网络协议选择通用的TCP/IP协议。详述了此嵌入式系统硬件和软件的设计思路,并介绍了嵌入式系统实现远程软件升级的工作原理。
The paper introduces the design for remote upgraded embedded system based on Ethernet. The chips of system class single chip computer C8051F020 and the network chip RTL8019AS is mainly adopted for hardware design,and the Keil Cx51 single chip high grade language is adopted for the software program,and the universal TCP/IP protocol is selected for network. The design theory for embedded system hardware and software is expatiated ,and the working principle for embedded system remote software upgraded is introduced.
