Design Of Embedded Application Development Platform

In recent years, the technology of embedded application development makes a great progress in the fields of PDA, smart mobile phone and so on. Facing with more and more new technologies, the Equipment manufactories have to change product platform time after time to satisfy the customers' consumption requirements, which will cause lots of repeated devotion. But in the view of software development, these products have lots of common characters, such as PIM, wireless internet access, various media play, real time operation and so on.Presently, many domestic and overseas famous enterprises and companies are extending their embedded application development platform products actively. However these embedded application development platforms' license fee are very expensive, technology support are limited, design document and source code are restricted, which will cause many difficulties for terminal equipment manufactories if they want to port the same exterior provided designing platform to different product platforms. And possess an own application development platform is the best way to solve the problem.Therefore, this paper represents an embedded application development platform solution, and the portability and expansibility are its basic features. Moreover, in order to let the third software provider take part in the application development on this platform, and make the applications be installed and run on the device at anytime, the opening of development and running environment is one of the designing targets too.The application development platform solution uses object oriented design method and abstraction, bridge design patterns. By using the capsulation, inherit, polymorphism characteristics of the object oriented designing method, this solution can achieve prospective design target. Because of the portability, expansibility, and opening of the solution, it will have broad applying area and well application prospect.
