摘　　要： 对于追求高效实施、定制性强的嵌入式系统应用开发而言,随着功能的增多,对架构设计的研究已经成为提高工程效率和解决维护难题的重要途径。以Zoran公司的COACH DSP系统为实例,总结以往COACH开发的方法及不足之处,结合嵌入式系统架构设计关键问题和成熟理论,设计一种基于消息驱动的DSP系统应用开发设计模式。新的模式在仿真实验中得到验证,有助于改善软件代码复用和开发效率。为其他嵌入式系统设计模式实践提供有益参考。 For the applications development of embedded systems pursuing efficient implementation and strong customisation, along with the increase of functions, the study on architecture design has become an important way to improve the engineering efficiency and resolve the difficuhies in maintenance. Taking COACH （ Camera On A Chip） DSP system of Zoran as the example, in this article we summarise previous COACH development methods and their inadequacies, and contrive a message-driven-based DSP system application development design pattern in combination with the key issues in embedded system architecture design and the mature theory. The new pattern has been verified in simulation experiment, it is beneficial to the improvement in software code reuse and development efficiency, and provides a useful reference for design pattern practices on other embedded systems.
