Abstract: The software architecture of ASAAC standard emphasizes on the modular and scalability of the whole system, but its safety is not enough because of using normal operating system as node system. Aiming at this problem, this paper uses ARINC653 partition operating system as ASAAC node system, designs a new ASAAC generic system management and puts it into the core software layer of ARINC653 operating system to improve the safety of integrated modular avionics system.

Key words: Integrated Modular Avionics(IMA), partition operating system, general system management, reliability

摘要： ASAAC软件体系结构侧重于整个系统的模块化、可扩展性，其节点使用普通操作系统导致系统可靠性不够。针对该问题，将符合ARINC653标准的高可靠性分区操作系统作为ASAAC软件体系结构的节点操作系统，设计新的ASAAC通用系统管理并将其植入ARINC653的核心软件层，使两者充分融合以提高综合模块化航空电子系统的可靠性。
