性能、价格和可靠性是评价一个系统的三大要素.对第五代计算机的性能研究与分析已有多篇文章进行了探讨.本文着重讨论第五代计算机的可靠性设计.分析由超大规模集成电路构成的第五代计算机中的可靠性与集成度间的尖锐矛盾.提出解决这种矛盾的方法.阐明第五代计算机必将是一个高可靠的容错计算系统.最后,简介我校在这方面的一些研究结果. Performance, price and reliability are the three major factors to evaluate a system.There are many articles on the research and analysis of the performance of the fifth generation of computers.This paper focuses on the reliability design of the fifth generation of computers.Analysis of the fifth generation of the computer by the ultra-large-scale The fifth generation of computer integrated circuits constitute the sharp contradiction between the reliability and degree of integration.This method of resolving this contradiction.Emphasis on the fifth generation of computer is bound to be a highly reliable fault-tolerant computing system.Finally, Some research results in this area.
