摘要: 基因存储是电子细胞的重要组成部分,已有的基因存储无法兼顾系统的可靠性和硬件消耗.设计了一种新型的基因存储结构,细胞采用相关冗余方式存储系统的部分基因.通过基因更新过程,基于相邻细胞的基因信息恢复故障细胞损失的基因.细胞内存储基因数目与阵列和目标电路规模无关,可由设计者根据系统需求设置.理论分析和仿真实验表明,该基因存储不仅实现了阵列功能分化和自修复,而且可在保持系统可靠性的前提下,降低基因存储的硬件消耗,可用于大规模仿生自修复芯片的设计.

关键词: 胚胎电子阵列, 自修复, 部分基因循环存储, 基因移位, 基因备份数目

Abstract: Gene memory is an important part of electronic cell,and the existing genes memory structure cannot take into account the reliability and hardware cost.A novel gene memory structure named partial-DNA cyclic memory was presented,and only part of the system's entire DNA was stored with correlated redundancy.The lost genes caused by faulty cells could be obtained through gene update according to the faulty cells' neighbor cells.The stored gene number is independent form the scale of embryonics array and target circuit,and can be set according to actual demand in design process.Theoretical analysis and simulation results show that the novel gene memory not only to achieve the embryonics array's functional differentiation and self-repair,but also reducing hardware overhead while keeping system reliability.The proposed gene memory can be used to design larger scale self-repair chip.

Key words: embryonics array, self-repair, partial-DNA cyclic memory, gene shift, gene backup number
