A Novel Embryonics System with Evolutionary Ability

Based on an analysis of the advantages and disadvantages of row/column elimination and cell elimination repair methods in embryonics (embryological electronics, embryonics), we developed a novel embryonics hardware structure with evolutionary ability and a corresponding self-repair method. The proposed embryonics system has a function layer, a repair layer and an evolution layer. Target circuit function is implemented through the function layer, column elimination self-repair is implemented by the repair layer, and the evolution layer can be used to initiate evolution of the circuit operating on the function layer. Importantly, the proposed self-repair method has evolution property. Depending on changes in self-repair capacity, two repair modes can be used: elimination self-repair and evolution self-repair. The faulty circuit can be repaired online in real-time through the elimination self-repair mode, and the evolution self-repair mode can fully utilize the redundancy resources through evolution of the circuit form. By combining these two modes, the embryonics system and self-repair methods presented here ensure that the circuit realized on the hardware can not only be repaired in real time, but also that utilization of embryonics and the circuit self-repair capacity are improved. Key-Words: embryonics, self-repair capacity, evolutionary ability, elimination repair mode, evolution repair mode
