胚胎电子细胞的部分基因循环存储结构

Structure of partial-DNA cyclic memory for embryonics cell

为了在保证胚胎电子系统可靠性的前提下降低系统的硬件消耗,提出一种新型的基因存储结构——部分基因循环存储,细胞只存储阵列的部分基因,通过细胞内、细胞间的基因循环、非循环移位实现阵列的功能分化和自修复,自修复过程中基因存储内容根据故障细胞数目进行自主更新。该存储结构中基因备份数目可由设计者根据系统可靠性和硬件消耗要求设置,不受阵列中空闲资源数目的限制。理论分析和仿真实验表明,该新型存储结构不仅实现了胚胎电子阵列的功能分化、自修复等功能,而且能够在保证系统可靠性的同时降低硬件消耗,具有较高的工程应用价值。

In order to reduce the hardware cost of embryonics system on the promise of ensuring system reliability,a novel genome memory structure—partial-DNA cyclic memory was presented,and only part of the system ＇s DNA was stored. The embryonics array ＇s functional differentiation and self repairing were achieved through the gene cyclic and non-cyclic shift in the cell and between cells,and the genes stored in memory were updated during the self repairing process. In this memory structure,the gene backups were set according to actual demand of system reliability and hardware cost,which were independent from the number of idle resources in embryonics array. Theoretical analysis and simulation results show that the new genome memory structure can not only achieve embryonics array＇s functional differentiation and self-repair,but also can ensure system reliability and reduce hardware cost,and it has a high practical engineering value.
