摘要/Abstract

摘要： 新一代模块化综合航空电子系统采用综合处理机（ICP）来进行任务处理，ICP采用时空隔离分区技术，来实现不同系统功能对系统资源的安全共享。基于具有两级调度时间隔离机制的实时操作系统，给出了航电系统ICP时间隔离分区的处理能力和调度周期的配置实现方法。最后，对现代综合航电系统ICP的隔离分区设计进行了实例分析，其结果对指导新一代航电系统设计具有重要的理论意义。

Abstract: The Integrated Core Processor（ICP） deals with all the system missions in the latest modular avionics，which has all the system missions share resources based on spatial and temporal partitioning mechanisms.This paper studies the two levels temporal partitioning real-time system firstly.Then，it gives the techniques to design temporal isolation safeguard partitions for ICP with configuring the processor speed and period of every partition.Finally，it makes the realization of temporal partitions for ICP，whose result has significance for the design of modular avionics.

Key words: temporal and spatial isolation safeguard mechanisms, processor speed of a partition, period of a partition, Integrated Core Processor（ICP）
