摘　　要：集成电路制造工艺的飞速发展,使得集成电路的特征尺寸不断减少和集成度不断提高,造成集成电路对工作环境的影响越来越敏感,发生软错误的几率不断增加,对可靠性造成重要影响。随着微处理器进入了多核时代,丰富的片上资源给软错误加固带来了很好的机遇。本文针对多核处理器中I/O系统软错误,提出了一种基于多核处理器的软件Scrub方法对软错误进行加固。测试结果表明,我们提出的软错误容错方法可以大大提高I/O系统的可靠性。With the development of integrated circuits, the transistor dimensions are reducing and the density is increasing, and lCs depend on work environment servers, so the possibility of soft error occuring becomes more often, which has important effect on the reliability of chips. Multi-core microprocessors have become the mainstream over the past few yesrs, the redundant resources in the multi-core mi- croprocessors providea redundant resource to enhance the reliability. A soft scrub method for multi-core processors is proposed to tolerate soft errors. The experimental results demonstrate that this technique can greatly increase the reliability of the I/O systems.
