摘　　要：嵌入式系统的开发通常包括硬件体系与软件实现两部分.ARM体系结构是当今嵌入式开发的主流板结构,而VxWorks是嵌入式开发的主要软件平台.从应用系统开发的层面角度,首先从代理网关实现出发,介绍ARM体系结构由网络接口和IC卡接口组成,接着从软件角度阐述系统实现该代理网关的功能,包括内部网络可以通过代理访问外网,远程配置安全策略,IC卡身份识别等.Development of embedded system usually includes hardware architecture and software implementation. The construction of ARM architecture is the mainstream of BSD nowadays, while VxWorks is the main platform for embedded system design. Considering the development of the application system, this paper first introduces the composition of ARM architecture from network interface and IC card interface, then it illustrates in detail the implementation of agent network gate on the point of software, including inner network access external network, remote configuration of security policy and identification of IC cards.
