In this paper, Meggitt decoder is improved for high speed decoding. This decoding method is explained by single error-correcting Hamming codes. Finally, decoding diagrams and steps are given. 本文对Meggitt译码器进行了改进,提高了译码速率,并以汉明码纠正单个错码为例说明此方法。文中给出的译码方框图及步骤,具有实用意义。 Techniques of fault diagnosis are one of the measures of raising computer reliability. Parity codes, single error correcting-double error detecting codes and single byte error cor- recting-double byte error detccting codes for fault diagnosis of computers are discussed on the basis of theory of error detecting and correcting codes in this paper. Function diagram of over- all logical designs are given. 故障诊断技术是提高计算机可靠性的措施之一,本文在研究检错和纠错编码理论的基础上,论述了用于计算机故障诊断的奇偶编码、纠一检二编码和纠字节错编码技术,并给出了总体逻辑设计框图。 The article describes a single error correcting codes, which can detect and correct single error. The principle is that the data coded by generating matrix and the error detected and corrected by correcting matrix. 本文描述了一种既可检测一位错误又可纠正一位错误的纠单错码.纠单错码的基本原理是利用生成矩阵来进行编码,利用校验矩阵来进行查错和纠错.
