| 释义 | error correction code(ECC) 纠错码;［改误码］ A code that provides an inherent method of correcting errors detected in received data. The process is termed forward error correction. Such a code provides for the introduction of redundant bits as necessary to make all correct bit patterns conform to a particular rule according to some algorithm. The hardware with which the code is used provides for the analysis of bit patterns that deviate from the rule in order to determine which bits are in error and to change them. 用一定的方法纠正接收数据中错误的一种代码,纠错过程称为前向纠错。主要为保证采用 冗余位能使所有的校正位模式按照某种算法与特定的规则相符合。使用这种纠错码时,硬件 对偏离规则的位模式进行分析,以确定哪一位有错并加以纠正。 |
