摘要
介绍了双星用户机系统组成和功能,运用软件工程的方法进行总体设计,分析如何优化任务划分和中断处理来提高系统的实时性,提出了适合本系统的任务间通信和同步方案,并给出基于DeltaOS的实现方法,最后总结了设计中容易出现的致命错误以及解决方案。本文的设计方法已经实现,运行稳定可靠并且具有良好的可扩展性。
This paper introduces the composing and function of double-star system terminal, uses methods of software engineering to do its top design, analyses how to optimize task-dividing and ISRs in order to improve real-time performance of the system, presents a solution to the communication and synchronization between tasks, and offers a realization method based on DeltaOS, finally summarizes incidental fatal errors during designing and the solution. These solutions have been realized in the system software and the result shows their strong stability and excellent expansibility.
