Research on Fault Tolerance of Evolvable Hardware
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.
