Abstract

According to the main problems of spacecraft embedded software design, the universal real-time architecture of spacecraft embedded software without operating system is proposed, and the data flow, control flow, time-sequence design techniques and methods under this architecture are given. The architecture aims at layering and decoupling, and integrates object-oriented and process-oriented programming ideas with task description word as the starting point. The main technical features are : the task modules run independently according to their respective task description word information, and do not affect each other ; task module controlled by the state machine, step by step execution, efficient operation ; inter-layer communication using queues, messages, notifications and other ways, data flow fluent. Finally, an embedded software design example of the universal real-time architecture is given. Compared with the traditional software development model, it has significant improvements in reducing software complexity, improving development efficiency and saving costs.
