Design And Implementation Of Embeded Browser Base On VxWorks

The quick development of internet gives new energy to embedded products, and it lead to a design revolution. A lot of embedded network application products appear. In the aspect of hand-end equipment, there is mobile phone which can via internet, personal digital assistant and MP3 display, etc. In the aspect of information home appliances, there is intelligence phone, internet TV, digital TV. In all of these embedded products, embedded browser is main application software to get information through internet.So at present, browser is not only limited to traditional on-desk browser. It also enters into non-PC domain-embedded system domain, which is just the research of this paper. The appearance of embedded browser makes on-desk browser a clumsy dinosaur. Although Microsoft is still hold the main percentage in the field of PC internet browser, more and more experts make sure that the swift growing up of embedded market will be the most popular browser. Because, in the environment of fast growing mobile communications market, embedded browser meets the needs and wants of people better. What the user of mobile phone and internet application equipment need, is not the excellent screen display of HTML, but the terseness technique which can give a optimal display of old text. That is the ability of get relevant information quickly. So, embedded browser will suit their needs of interface and individual setting.And as the development of internet and the intense combination of internet, information home appliances and industry control, the unit of embedded equipment and internet will represent the real future of embedded technology. Most important, embedded browser is an indispensable part. This paper aims at the trend of today's browser development. Basing summarize and analyses of exist embedded browser products, the paper gives its design and carrying out scheme. And it expatiates the frame of browser from four aspects-scanner, analyzer, layout and GUI, in order to achieve a browser model of lower complication, less memory and better display.The design and carry out of this embedded browser uses one of the most popular real-time operate system, VxWorks, and other tools of Tornado. And it finishes the development and debugging work by using VxSim emulator and WindML.In the main part below, the paper will introduce the outline design, detail design, browser implement and future application.
