基于VxWorks嵌入式系统的浏览器设计

Design of WWW Browser for Embedded System of VxWorks

为了探讨嵌入式系统用户接口软件的设计方法,依据VxWorks嵌入式系统的网络机制以及ARM处理器的内核原理,采用Socket及多线程通信技术,开发了一个基于VxWorks嵌入式系统的浏览器,在此基础上探讨了嵌入式系统软件的特性.此软件在PC机上基于VxSim模拟器运行的结果表明,该浏览器对简单图形界面的显示效果达到了实用浏览器的水平,且代码为2100行,所需容量仅为2.9M字节,满足嵌入式软件独特的微代码及高效实时性要求.

To discuss the interface part soft of embedded system, based on network system of VxWorks and kernel theory of ARM processor, using the technology of Socket and multithreading communication, a browser based on VxWorks was developed, and the character of VxWorks embedded system was deeply studied. The result of the soft which went round on VxSim at PC showed the effect of browser which displayed simple interface was practical, and the number of the code is 2100, occupying 2.9M bytes in memory, satisfying the special request, such as micro-code, high efficiency and real -time, which was needed in embedded system.
