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实现电子系统的实时自重构,它包括各种能够适应环境变化,并且在运行期间不断改善自身性能的电子系统。演化机制的引入使演化硬件具备了自修复的特性,其自修复特性来自于其对环境的自适应能力和对自身内部结构的自组织能力。利用演化硬件调整内部结构是实现自修复系统的重要途径。演化硬件所具有的自组织、自适应和自修复的特点能够在不需要人工干涉的前提下进行对故障的自诊断和自修复,不仅可以修复已知错误,还能够发现和修复未知的错误,为提高复杂系统的可靠性提供了全新的途经。Evolvable hardware is the most potential technology to solve the contradiction between system design complexity and system reliability.It is a real-time self-reconfiguration of electronic system by integrating evolution mechanism.It includes a variety of electronic systems that can adapt to environmental changes and constantly improve their performance during operation.The introduction of evolution mechanism makes evolvable hardware have the characteristics of self-healing,which comes from its self-adaptive ability to the environment and its self-organizing ability to its internal structure.Using evolvable hardware to adjust internal structure is an important way to realize self-healing system.Evolvable hardware has the characteristics of self-organization,self-adaptive and self-healing.It can not only repair the known errors,but also find and repair the unknown errors,which provides a new way to improve the reliability of complex systems.
