提高系统容错性的软件技术

计算机在现代军事装备中的作用日益重要,他在装备研制中所占工作量的比例越来越大。由于军用计算机的工作环境一般较恶劣,常容易引起计算机电源不稳定等问题,因此,如何保证计算机系统的可靠性已成为影响装备质量的关键因素。本文综合分析嵌入式系统中提高计算机容错性的常用技术,并给出采用软件恢复块实现掉电恢复的实例。

Software Technology for Raising System Error - tolerance Property

Computer is playing more important role in present-day military facilities,thus the computer efforts account for more and more ratio in the development fare of facilities.Due to the execrable working environment of military computer,the no-stability of computer power-supply is vulnerable to occur.So,How to insure the reliability of computer system becomes a fatal factor of facility quality.The paper universally analyzes the common used technologies to raise computer error-tolerance properties in embeded systems,accordingly,an example of power-off recovery by software way is given.
