Research On Bio-inspired Self-repairing Technology Based On Bus Structure

As electronic systems become more and more complex, the fault-tolerant abilityhas become one of the most important quality indexes to evaluate a system. Redundancefor key modules is chosen as the general method to improve the reliability of electronicsystem. However, this method has some shortcomings like limited fault-tolerant abilityand poor environment adaptability. Thus the Embryonic Array (EA) is put forward andit provides a new technology to improve the reliability of electronic systems, in whichfault toleration is accomplished by distributed electronic cells. Embryonic Array hasbetter fault-tolerant ability and environment adaptability. But it also shows thedisadvantages of large consumption of memory and low efficiency of self-repairing.Therefore, taking biological endocrine system for reference, the bio-inspired electronicarray based on bus structure and endocrine bio-inspired self-repairing mechanism waspresented. The main research of the paper shows as follow.(1) With the analysis of the communication principle of biological endocrinesystem, bio-inspired self-repairing electronic array has been put forward. In this arrayall cells connect with each other only directly via bus, which makes it easy to placingand routing. And the configuration memories of work cell only store their ownconfiguration information, thus the resource utilization ratios are improved.(2) Taking the communication principle of biological endocrine system forreference, endocrine bio-inspired self-repairing mechanism has been designed, in whichthe process of repairing only relates with fault cell and idle cell. It only changes theconfiguration information of idle cell when repairing the array. Therefore, the speed andefficient of the self-repairing process are higher than the traditional structure.(3) The endocrine bio-inspired fuzzy controller of single stage inverted pendulumwas designed and realized, and both simulation and experiment were made to validatethe control capability and self-repairing ability, which further validated the quality andefficiency of the endocrine bio-inspired electronic array and self-healing strategy,After all, the main work was summarized and some advices for further researchwere also proposed.
