基于低复杂度编译码的数据流错误纠错方法
Data Stream Error Correction Method Based on Low Complexity Coding and Encoding
摘要
Abstract
This paper designs a kind of encoding and decoding algorithm with a low complexity based on the data correction method to resolve the data stream errors which Single Event Upset(SEU) may bring. It uses the theory of linear block codes to analyze various methods of data fault tolerance, and designs a kind of encoding and decoding algorithms with a low complexity of linear block code from the encoding and decoding principle of linear block codes,the fault-tolerant coding method can effectively correct single-bit data errors caused by SEU, with low fault-tolerant overhead. Fault injection experiments show that this method can effectively correct data errors caused by single event upset,compared with other common error detection or correction methods,error correction performance of this method is superior,while its fault tolerance cost is less.关键词
