基于安全分区操作系统的容错计算机软件架构

Fault-tolerant Computer Software Architecture Based on Partition Operating System

摘要:

机载计算机的综合化程度越来越高，综合了飞行器的多种任务功能，需要满足不同系统不同余度配置的安全要求。这种高可靠的容错计算机对软件的要求越来越高，为了确保不同系统应用程序在时间上空间上的彼此隔离互不影响，在高安全性的实时操作系统中提出了分区（Partition）的概念。介绍了一种高可靠机载容错计算机的系统结构，以及在INTEGIRTY分区操作系统下容错计算机的软件架构、系统调度、余度管理等

Abstract:

Airborne Computer are becoming more and more integrated ,It integrates multiple mission fun actions of aircraft, Airborne Computer need to meet the safety requirements of different redundancy of systems。The Computer’s software require more Complicated ,In order to ensure different system applications are isolated from each other in time and space ,the concept of Partition is proposed in operating system。 The paper introduces an architecture of a highly reliable fault-tolerant computer and its software architecture、system scheduling and redundancy management under ITEGRITY partition OS。
