Abstract:

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 self-repair 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.

Key words: embryonics electronic cell array (EECA), reliability, hardware resource consumption, self-repair strategy, idle cell, multi-state system theory
