A High-Performance Engine's Design And Research For BREW Application Of CDMA System

Due to the development and maintenance of many BREW applications, I recognize that it would be better if there was a engine to support most BREW applications. We can shorten the development and maintenance time by using this engine. Based on such considerations, I hope I can design and develop a high-performance engine for BREW application according to my development experience. After that, we can have a better understanding about the new BREW platform through the solution of technical difficulties.In this paper, I implement a high-performance engine for BREW applications according to a deep understanding about BREW platform and many good design patterns. We must know a platform very well to develop an application engine with good reusability and scalability on it. So I introduce the important core mechanism of BREW in the beginning. In these mechanisms, the BREW interface mechanism and the event handling mechanism are the most important. The engine is designed by several layers and divided into many modules. Classified by different functional modules can make the program structure more clearly. And it will also reduce the complexity of the problem. Meanwhile, modules can be used by different applications without changing. On the basis of the core module, there are state management module, menu module, file module, sound module, display module, interrupt processing module, debug module, network module and touchscreen module. I design these modules carefully by using good design patterns to improve development efficiency. Finally, I introduce some useful development experience which was summarized in my development process in the last chapter.
