目前在工业与非工业用计算机上频繁采用的高级错误校正码确实有助于得到独立、可靠的系统. 计算机编码与通讯编码有所不同,它必须满足种种特定的速度、功率及区域限制.对于这种代码,计算速度增加时相应地提高编码与译码速度是有利的.因此,用高速VLSI实现编码与译码是工程上主要考虑的因素.但是,速度不是唯—的因素,可靠性也很重要.因编码器和译码器采用与编码保护部件相同的技术,故不能认为他们是无故障的.由此,编码器与译码器中实现容错也是—项重要的课题. 在计算机编码中,有时也可以把错误位置的 Current high-level error-correcting codes that are frequently used on industrial and non-industrial computers do help to get an independent, reliable system that differs from a communication code in that it has to meet a variety of specific speed, power, and area constraints. This code is advantageous in terms of increasing the speed of encoding and decoding accordingly as the computational speed increases.So coding and decoding with high speed VLSI are the major engineering considerations but speed is not the only factor and reliability It is important that encoders and decoders are not fault-free because of the same techniques used to code the protective components, and fault-tolerant implementations in encoders and decoders are also an important issue in computer coding In the wrong place sometimes
