摘　　要：当前新一代航空电子呈现出向综合模块化方向发展的趋势。这一变化对航电设备中使用的机载实时操作系统提出了新的要求。机载实时操作系统需要将各类机载软件融合到同一个CPU上,实现综合化;同时又要保证各类机载软件独立运行,不相互影响,实现模块化。这就需要操作系统改变管理软硬件资源的机制,支持对于各类机载软件实施分区调度,并保证分区的独立与安全。ARINC 653标准介绍了分区的概念,对面向综合模块化航空电子设备(IMA)的实时操作系统的安全机制提出了具体要求。Nowadays, the avionics system of new generation trend to be high integrated and modular.It has placed new requirements on the real-time operating system for avionics. The real-time operating system for avionics can consolidate multiple applications into a single CPU,and then support the realization of syetem integration.Meanwhile,it can insure independent work of airborne software,and then support the realization of syetem modularization. The operating system should change the management mechanism,support partition scheduling for kinds of airborne software,and insure the independence and Security of partition.AR, INC 655 introduces the concept of partition and detail security requirements of real-time operating system for IMA.
