摘　　要：演化硬件是当前解决系统设计复杂度和系统可靠性这一矛盾最有潜力的技术。它是通过融入演化机制来实现电子系统的实时自重构,并具备了自组织、自适应和自修复的特性,这为硬件容错技术开辟了一条崭新的途径。目前演化硬件主要采用对自身整体结构的重配置或者对局部结构的重配置来实现系统的自修复。本文提出了一种数字电路的自重构修复方法,该方法能够以消耗少量的冗余资源为代价获取良好的容错性能。通过实验证明了此演化设计方法运用到容错系统设计中的可行性和有效性。Evolutionary hardware is the most potential technology to solve the contradiction between system design complexity and system reliability.It realizes the real-time self-reconfiguration of electronic system by integrating evolution mechanism,and has the characteristics of self-organization,self-adaptation and self-repair,which opens up a brand-new way for hardware fault-tolerant technology.At present,evolutionary hardware mainly uses reconfiguration of its whole structure or reconfiguration of local structure to realize self-repair of the system.In this paper,a self-reconfiguration repair method for digital circuits is proposed,which can obtain good fault-tolerant performance at the cost of consuming a small amount of redundant resources.Experiments prove the feasibility and effectiveness of this evolutionary design method in fault-tolerant system design.
