Modeling and Automatic Code Generation of Wireless Communication Application

摘要

With the quick development of the wireless communication and embedded system market, the popularization of wireless communication applications brings us so many new opportunities. Efficiency and quality of the applications are becoming the most important facts in the competition. We are looking for the more reliable, complex and flexible applications, however, the traditional development mode depends on the personal skill can not meet our requirements any more. We need a brand new development mode eagerly. This thesis introduces a sort of mechanic about modeling and automatic code generation, which aims at the wireless communication applications. It analyses the most time-consuming and variable parts, and sets their abstract models up by a simple model description language. And at the same time, there is a code template for every model. Each template contains the real source code used to implement the entity represented by the corresponding model. Then if the developer wants to develop an application, the only thing he/she need to do is establishing the application model using the model description language. The automatic code generation process can generate the right and well-format source code automatically by parsing the application model. The automatic code generation mechanic is based on the EFSM(Extended Finite State Machine). It abstracts every screen to a corresponding state and abstracts the jump between the screens to state transition. The EFSM is an event-driven model which contains a finite state set, the system jump from a state to other one according to the input event. The whole code generation is a process distills states and establishes the system-level EFSM. After being established, the EFSM shall be checked for the consistency and accuracy at first, and then be parsed event driven, and finally be converted to the right objectsource code combining the corresponding code template. This modeling and automatic code generation mechanic changes the traditional development mode by overcoming many defects, such as bad quality, low efficiency and high cost. It can really enhance the quality of the applications and the efficiency of the development. With the huge increase of the wireless communication market, this sort of development concept will be applied to the wireless communication application development widely more and more.
