| 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. |
