中文摘要：

提出一种基于演化硬件的补偿容错模式,将被检对象和重构对象分离,以避免自重构容错模式可能对系统造成破坏的危险.该容错模式在不影响原电路工作的前提下,利用演化硬件的自适应特性,重构出相应的电路对出错电路进行输出补偿,从而达到容错的目的.实验表明,补偿容错模式能以少量的冗余代价换取更优的容错性能,并且修复时间比自重构容错模式短,有利于实时容错.

英文摘要：

A compensation fault tolerance model based on evolvable hardware is proposed,it separates the failed system and reconfigurable hardware to avoid the risk of destruction which exists in self-reconfiguration fault tolerance.It generates corresponding circuits by the adaptability of evolvable hardware to compensate for failed circuit,so as to achieve fault tolerance.The experimental results prove that the proposed fault tolerance model achieves great fault-tolerant capability with little redundancy.Moreover,it costs less recovery time than self-reconfiguration fault tolerance,which conducive to realize real time tolerance.
