胚胎电子细胞阵列中空闲细胞的配置

空闲细胞是胚胎电子细胞阵列(EECA)实现自修复的前提,空闲细胞越多,系统的可靠性越高,但过多的空闲细胞也将带来巨大的硬件资源消耗。在航空航天等领域,电子系统追求高可靠性的同时,硬件资源消耗也必须考虑,为优化胚胎电子细胞阵列中空闲细胞的配置,以阵列可靠性和硬件资源消耗为出发点,将多态系统理论引入到阵列的可靠性分析中,优化可靠性计算模型。针对经典胚胎电子细胞阵列,在不同自修复策略下,仿真并分析阵列的可靠性、硬件资源消耗与空闲细胞配置的关系。根据研究结果制定了不同自修复方式下空闲细胞的配置方法,同时兼顾可靠性和硬件资源消耗的要求。同时,研究了确定规模的胚胎电子细胞阵列自修复方式的选择方法。本文研究成果对推动胚胎电子细胞阵列的实际应用具有重要的意义。

Configuration of idle cells in embryonics electronic cell array

Idle cells are the premise of self-repair in embryonics electronic cell array (EECA),more idle cells mean more chances for self-repair,and thus higher reliability of the system.However,more idle cells also bring huge consumption of hardware resources.In the field of aerospace,in the pursuit of high reliability of electronic systems,hardware resource consumption must be also taken into consideration.In order to optimize the configuration of idle cells in EECA,the reliability and the hardware resources consumption of EECA are analyzed as the starting point,and multi-state system theory is introduced into the reliability analysis of EECA to optimize the reliability calculation model.For the classical EECA,under different selfrepair strategies,the relationship between the reliability and the hardware resources consumption of EECA with the configuration of idle cells are simulated and analyzed.Based on the research simulation results,the configuration method of idle cells with different self-repair strategies is formulated,which can give consideration to both requirements of higher reliability and lower hardware resources consumption of EECA.The method for selecting the self-repair strategy for the EECA with known scale is also studied.The simulation and analysis results show that the proposed methods can have great influence on application of the EECA.
