计算机存储系统的9位字节单向错误检测码

9-bits Undirectional Error Detecting Codes for Memory System

本文介绍了一种计算机存储系统中的单向错误检测码，系统构成采用９位字节，其中８位数据位，１位校验位，并使用一个单独的附加奇偶校验字节。单向错误检测码有两类，一类每个字节包含固定的奇偶校验位；另一类每个字节包含的校验位的构成方式是任意的。

A kind of ulldlrcctlonal error detecting codes for computer memory system is given in this paper.The system is organized in 9-bits,8-bist fof data, 1-bit for parity, and use an additional parity byte. There are two kinds of such undircctional error detecting code:one is the parity bit in each byte is fixed,another is the construct of parity bit in each byte is changeable.
