摘　　要：针对嵌入式应用软件并行设计和调试困难这一共性问题,研发了任务间通信服务ICS(Intertask Communication and Serv-ices)消息总线平台库,并据此提出一种基于ICS工作机制的嵌入式应用层软件架构。对复杂任务中相对独立的功能模块用进程来实现,创建进程的ICS邮箱,并借助于ICS消息总线平台来实现进程间安全的数据交互和流畅的行为控制。这使得进程化的不同模块可并行研发,并通过ICS消息实现模块间的并行通信和测试。最后介绍了这种架构模式在具体研发项目的应用和效果。Considering the common problem of the difficulties in parallel designing and debugging the embedded application software,the author studied and developed the message bus platform library of intertask communication and services（ICS）,and presented according to that an embedded application layer software architecture based on ICS work mechanism to resolve the problem.The comparatively unattached function modules in the complicated task are implemented with processes,and the ICS mailbox is created for each process.Via the ICS message bus platform,secure data exchange among processes and fluent action control of each process can be achieved.Those make it possible to develop the different modules in parallel during the processes and to carry out parallel communication and test between the modules via ICS messages. In the end,the author introduced the application of the architecture mode in specific research and development project and the effect.
