Abstract :
A digital circuit with self-repairing characteristic based on embryonic cellular array, which attempts to draw inspiration from the biological process of ontogeny, to implement novel digital computing machines endowed with better hardware fault-tolerant capabilities is researched in this paper. The self-repairing digital circuit (SDC) consists of the two-dimensional electronic cellular array, the SDC´s structure and the self-repairing mechanism are expounded, and the design of the cellular circuit based on LUT (look-up table) is proposed. Then, a multiplication circuit is presented as an example of the application of the SDC, the function and self-repairing ability of the multiplication circuit by SDC are demonstrated by the simulation results
