综合模块化航空电子系统软件体系结构综述

 作为降低系统生命周期费用（LCC）、控制软件复杂性、提高软件复用程度的重要手段之一，软件体系结构已成为航空计算领域的一个主要研究方向。阐述了综合模块化航空电子（IMA）的理念，分析了推动IMA产生和发展的主要因素。总结了ARINC 653，ASAAC，GOA以及F-22通用综合处理机（CIP）上的软件体系结构研究成果，并讨论了IMA软件体系结构需要解决的若干问题及其发展趋势。在此基础上，对中国综合航电软件体系结构研究提出了一些见解。

Overview on Software Architecture of Integrated Modular Avionic Systems

As an important means to decrease system life cycle cost（LCC）, control software complexity, and improve the extent of software reuse, software architecture has been a mainstream research direction in the aeronautical computer field. This article expatiates the concept of integrated modular avionics (IMA). Three major factors are analyzed which promote the development of IMA architecture. IMA software architectures presented by ARINC specifications 653, ASAAC, GOA, and F-22 common integrated processor (CIP) are summarized. Discussion about some problems to be solved and the development trend is made for IMA software architecture. Finally, some views are presented about IMA software architecture research in China.
