用于存储器容错的纠、检单向字节错误码的设计

On Code Constructions for Computer Fault-tolerant Byte Organized Memory Subsystem

逻辑电路设计，关键是逻辑功能的实现和可靠性．本文设计了一种纠、检单向字节错误的计算机容错存储子系统．和ＲＳ码等用于纠字节错误码相比，在纠、检单向字节错误时，具有更高的编码效率和码率，便于软、硬件实现和在片集成．

A computer fault-tolerant byte organized subsystem which based on the byte error-correcting codes is presented; two kinds of byte unidirectional errorcorrecting codes used for fault-tolerant are constructed. Compare to the other byte error-correcting codes such as RS codes, the constructed codes have higher code efficiency and code rate. They can be easily realized by software or hardware, or integrated in the memory devices.
