A self-optimized bionic self-repairing hardware fault reconstruction mechanism design

Abstract

The invention provides self-optimized bionic self-repairing hardware fault reconstruction mechanism design. The self-optimized bionic self-repairing hardware fault reconstruction mechanism design specifically comprises the following steps that a bionic self-repairing hardware fault reconstruction model is established, wherein a target functional circuit is mapped to bionic self-repairing hardware;Performing fault detection on the mapped bionic self-repairing hardware until a fault cell nf is detected; Searching bionic self-repairing hardware globally, searching for an idle cell nt closest toa fault cell nf, migrating a functional node vf associated with the fault cell nf to the idle cell nt, and calling a configuration scheme at the moment as an initial feasible solution x0; And findingout a configuration scheme of the optimal feasible solution xbest of the fault cells nf by using a variable neighborhood search algorithm. A bionic self-repairing hardware reconstruction mechanism isdesigned by adopting a variable neighborhood search algorithm, so that the fault reconstruction process can be optimized, the comprehensive performance of a reconstruction circuit is ensured, the utilization rate of idle cell resources is improved to the maximum extent, and meanwhile, the requirements of calculated amount, online implementation and the like are considered. The method is applied tothe field of electronic circuit reliability.

Description

technical field [0001] The invention relates to the field of electronic circuit reliability, in particular to a design of a self-optimized bionic self-repair hardware failure reconstruction mechanism. Background technique [0002] Bionic self-healing hardware began with a novel field-programmable gate array proposed by Mange et al., drawing on the developmental process of multicellular organisms. The basic idea is to apply the bionic mechanism to the electronic circuit design process, so that the electronic circuit can autonomously and dynamically change its own structure and parameters according to the changes in the working environment to obtain the desired performance, similar to biological self-adaptation. , self-healing and other characteristics. [0003] The minimum structural and functional unit of bionic self-healing hardware is a general-purpose reconfigurable electronic cell, which contains configuration registers, which are used to simulate the genome of biologic...

Problems solved by technology

However, it is impossible to optimize the reconfigured circuit, which makes the initial layout of the functional circuit more restricted, and the design flexibility is not high; idle cells cannot replace and repair faulty cells at any position, and the resource utilization rate is low; the reconfiguration process cannot take into account the circuit network. length, circuit timing characteristics degrade after repair
