Abstract: For large scale or very large scale embryonic circuits, in the process of function differentiation and self-repairing faced with the problems such as huge hardware consumption, huge time consumption and hard to completed and so on, in this paper, a Bus-based Embryonic Array（BEA） is proposed, which is based on the function decomposition. The structure of BEA is designed, a new self-repairing strategy is put forward, and the comparison of the BEA with the original array structure is analyzed. The resource consumption and the reliability of the BEA are analyzed with different cells composition. Considering the resource consumption and the reliability of the BEA, the choice of spare cells in BEA is researched, to ensure the less resource consumption with the same reliability. The research on the spare cells in the BEA is helpful to the design of the real circuit.

Key words: bus-based embryonic array, function model, reliability, resource consumption, spare cells

摘要： 针对大规模或超大规模胚胎细胞阵列的功能分化过程和自修复过程资源消耗大、耗时长及实现复杂等问题，提出了一种基于功能分解思想的新型总线型细胞阵列结构。对总线型细胞阵列结构进行了设计，制定了相应的故障自修复策略，并与现有的胚胎细胞阵列结构做了对比分析。同时分析了功能块内细胞组成不同的情况下，阵列的资源消耗情况和阵列的可靠性情况，研究了功能块中空闲细胞数量的选择，同时兼顾硬件资源消耗和阵列的可靠性两方面的问题，保证系统在一定的可靠性前提下资源消耗较少，为实际电路设计提供支持指导。
