摘　　要：伴随新一代航空电子的综合化趋势,机载软件对机载操作系统提出新的要求。通过管理系统的软硬件资源,包括内存、CPU、通信等,机载操作系统将各类机载软件融合在同一个CPU上,实现综合化。该文给出一种面向航空电子的分区操作系统的实现框架,支持二级调度,对于各类机载软件实施分区调度,并且分区的运行互不干扰,保证了分区的安全性。To cope with the trend of system intergration in modern avonics, airborne software have placed new requirements on the operating systems where they reside. Through the management of system hardware/software resources, including memory, CPU, and communications, operating systems for avionics can consolidate multiple applications into a single CPU, and then support the realization of syetem integration. With these respects, this paper presents a model for implementing the partitioning operation system for avionics, which supports a two level scheduling algorithm ~hat enables the scheduling of various airborne applications in multiple patitions, prevents application interfering between partitions, and therefor guarantees the safety requitement for the patitioning system.

关 键 词：分区操作系统 二级调度 调度窗口
