Embedded System Design And Implementation, Of The Wap Browser

WAP-Based browsing service is very attractive in mobile value-added services. So far, as one of the indispensable software, WAP browser has replaced Web browser on mobile facilities. Hence, WML, an ingredient in WAP pages, is getting more and more attention.This paper mainly focuses on interpreting WML in resource-limited embedded systems. Both WML and HTML are members of Markup Language family. Although they are in similar format, WML possesses its own characteristics in order to adapt to hardware parameters of mobile facilities. Firstly, this paper analyzes the structure and characteristic of WML followed by the conceptual description of its interpretation. Then, elementary data structure and implementation of analytical status machine which are adopted in the interpretation of WML for resource-limited embedded systems are proposed. Both analytical methods and final data structure are discussed in detail.Finally, a primary idea on the design and implementation of WAP browser in embedded systems is put forward through format and display description of WML analytical results. The main project of this paper is based on VC++ 6. 0 in Windows XP system. All core codes of the project are written with ANSI C while words display and system function utilize VC++ MFC class library functions and ANSI C standard library functions. User-defined external interface functions are introduced for all core codes so that when core codes are transplanted to other embedded operation systems, system functions in the target system can be used to implement the custom interface functions which will make it convenient to transplant the whole project and guarantee the progress of your project.
