【摘要】：典型的航空航天嵌入式计算机具有很多共同的特点,在体系架构的设计方面表现尤为突出。从飞机飞行控制计算机、导弹制导控制计算机和星载计算机3种典型嵌入式计算机入手,分析了航空航天行业嵌入式计算机的体系架构特点和共性技术,从模块化、网络、综合化、集约化、长寿命、COTS和开放性7个体系架构特征开展研究,归纳出通用架构、成本控制和适应发展3个评价维度,从而构建了针对这类嵌入式计算机的体系架构评估模型。对每个体系架构特征提出了基本的评判原则和具有可操作性的参考项,并给出了整机、评价维度和体系架构特征三者的分级之间的关系,以此便可对嵌入式计算机进行分级,以满足不同的评估需求。以两种先进的航空嵌入式计算机的评估为例,说明了评估的过程和方法。评估实例表明,该评估模型清晰、有效、实用。
[Abstract]:Typical aerospace embedded computers have many common features, especially in the design of architecture. Starting with three typical embedded computers, such as aircraft flight control computer, missile guidance control computer and spaceborne computer, this paper analyzes the architecture characteristics and common technologies of embedded computer in aerospace industry. The characteristics of integration, intensification, long life, COTS and openness are studied, and three evaluation dimensions, namely, general architecture, cost control and adaptive development, are concluded. Thus, the architecture evaluation model for this kind of embedded computer is constructed. The basic evaluation principles and operable reference items for each architecture feature are put forward, and the relationships among the whole machine, the evaluation dimension and the architecture feature are given, so that the embedded computer can be graded. To meet different assessment needs. Taking two kinds of advanced aeronautical embedded computer as an example, the evaluation process and method are explained. The evaluation example shows that the evaluation model is clear, effective and practical.
