摘要

开发了用于同时检测t字节单向错误(t- ubed)的代码。一些构造的代码还提供所有单向错误检测(AUED)。这类代码与AUED代码的不同之处在于，一个字节中的错误可能是1到0的形式，而另一个字节中的错误可能是0到1的形式。所开发的代码用于长度为9的字节，由八个数据位和一个奇偶校验位组成，并且除了奇偶校验位外，还利用一个字节用于奇偶校验信息。在不同的假设下，构建了从2-UBED到4-UBED和2-UBED+AUED到3-UBED+AUED的不同保护代码。

Unidirectional 9-bit byte error detecting codes for computer memory systems

Codes are developed for detecting unidirectional errors in t bytes simultaneously (t-UBED). Some of the codes constructed also provide all unidirectional error detection (AUED). These classes of codes are different from AUED codes in that the errors in one byte may be of the form 1 to 0 while in another byte they may be of the form 0 to 1. The codes developed are for bytes of length nine consisting of eight data bits and one parity bit and utilize one byte for parity check information in addition to the parity check bits. Under various assumptions, codes varying in protection from 2-UBED to 4-UBED and 2-UBED+AUED to 3-UBED+AUED are constructed.<>
