A new reconfiguration mechanism of bio-inspired self-repairing hardware based on variable neighborhood search algorithm

The bio-inspired self-repairing hardware greatly enhances the reliability of the circuit by endowing the circuit with the self-repairing property similar to that of the biological tissue, so it has broad application prospects. In order to overcome the shortcomings of current bionic self-repair hardware, such as not flexible enough, low utilization of spare cells, and insufficient consideration of wiring resource overhead and self-repairing time. This paper proposes a reconfiguration mechanism based on variable neighborhood search algorithm, which can restore the array function to normal only by changing the faulty electronic arrays in a small scale. At the same time, it can make full use of the spare cells in the array, and maintain a better wiring resource overhead and self-repairing time within a certain number of faulty cells.
