| The singlechip application technology is a computer control technology applied most widely recently, and the expansion of the peripheral circuit plays a very important role in the development of singlechip application system. Based on a detailed analysis for traditional way for the expansion of the peripheral circuit, we put forward a new method to expand peripheral circuit, which is to realize more functions of peripheral circuit on the same chip by construct a general platform for the expansion of microcomputer's peripheral circuit, and which is to make full use of resources of singlechipIn this paper, we firstly introduce the basic knowledge for application system of singlechip, and then based on the analysis for all the methods of peripheral circuit expansion, we put forward the idea of designing for general platform of microcomputer's peripheral circuit. Focus on the problem of design for general platform of microcomputer's peripheral circuit, we study the realization of common functions for peripheral circuit based on MSP430 series chip of Tl Company and give a detailed layout and design for the constructing of general design platform, finally we put forward two platform realization methods for both static configuration and dynamic configuration.The implementation of the model shows that applying this platform in the development of singlechip application system can facilitate the configuration of peripheral circuit, and simplify the system architecture, enhance the stability and adaptability for the system, also our work can enhance the efficiency of system development and drive the work of standardized design for the singlechip application system forward. |
