摘要
在对车载显示系统功能需求分析的基础上,针对QNX操作系统高度模块化的应用软件体系的特点及良好的图形开发环境,提出了一种高可用性的应用软件设计结构。该结构将软件分成多个模块,通过消息机制实现模块间的数据传输和模块管理,这是使软件在效率和可靠性方面具备优势的重要技术措施。
Based on the analysis of functional requirements for on board display system,an application software design structure with high availability was proposed according to the high modular application system and good graphic-development environment of QNX operating software.The design structure divided software into several modules so as to realize the data transmission between modules and the module management by messages,which is an important technical measure of optimizing efficiency and reliability.
