Abstract:The core algorithms and relevant difficulties of the parsing of the information of Web pages and the layout and display of data were discussed detaily.Using multi-task concurrency mechanism of VxWorks and combining with binary semphore,it achieved geting web page and parse_layout operation at the same time,it not only reduced the memory pressure of the system,but also improved the efficiency of the browser.In addition,using the bitmap and realizing the matching of HTML tags by combining the Hash function,it could improve the efficiency and spend of parsing greatly.
Keywords:embedded browser  VxWorks  parsing  layout
