【摘要】 针对目前国内外星载系统软件可重构性较差的问题 ,提出了一种基于软件总线的星载系统软件结构。首先 ,介绍了软件总线和软构件的结构。其次 ,阐述了星载实时多任务操作系统中混合任务调度算法的设计。最后 ,对这个混合任务调度算法的正确性给出了证明更多还原

【Abstract】 This paper proposes a structure of on-board system software based on software bus, for the poor reconfiguration of on-board system software at home and abroad at present. Firstly, the structure of software bus and configuration is introduced. Secondly, the algorithm in the real-time multi-tasks operation system is designed. Finally, the correctness proof of the periodic and aperiodic task scheduling algorithm is given.更多还原
