本文提出B邻接片错误定位码的概念,并具体给出两类定位码。其中一类定位码的优点是冗余度低,另一类定位码的优点是译码简单。当发生一个B邻接片错误时,定位码不仅能够检测到错误,而且能够确切指出错误产生的范围。或者,当错误较少时进行纠正,而当错误较多时进行定位。因此,在计算机的内存贮器采用定位码:发生一位错时纠正,发生多位错时定位,并更换备用插件,将是提高计算机可靠性和可维护性的一种有效途径。
In this paper, the conception of error locating code of B abutment is proposed and two kinds of locating codes are given. One of the advantages of the positioning code is the low redundancy, and the other advantage of the positioning code is that the decoding is simple. When a B-contiguous patch error occurs, the positioning code not only detects the error, but also specifies exactly where the error occurred. Or, correct it when there are fewer errors, and locate when there are more errors. Therefore, the use of a locator code in the memory of a computer: correcting when a fault occurs, locating when a multi-bit occurs, and replacing a spare plug-in will be an effective way to improve the reliability and maintainability of the computer.
