摘要
介绍了信息系统可信性的概念,选用了IBM POWER6浮点乘加部件中的算术运算为实例,对提高浮点运算部件中计算可信性的关键技术进行探究,为研究计算机算术运算的可信性提供了一定的参考。
This paper introduces the credibility of information system, and takes the floating point arithmetic operations on IBM POWER6 for example, provided the key technology in floating point calculation to improve the credibility, which provides a certain reference for study the credibility of the computer arithmetic operations.
