随着电子技术的飞速发展,电子产品的微型化和智能化使其成为人们日常生活的重要组成部分,由此人们对系统的稳定性和可靠性提出了更高的要求,容错技术已成为当前研究热点。全文首先提出一种三模异构冗余容错系统架构平台,该平台利用演化机制有效构建成功个体池,从而确保系统中三个冗余模块出错时的实时修复能力。为了进一步提高成功个体池中演化个体生成效率,引入交互式两阶段评估演化策略,从演化个体适应值及个体间的异构度两方面评估优化对系统性能进行了改进。最终以三位乘法器为例进行实验,结果表明该演化策略在演化效率上明显高于传统1+λ演化策略,同时也确保了系统生成个体的多样性,增强了该平台的容错性能。
With the rapid development of electronic technology, the miniaturization and intelligentization of electronic products make it an important part of people's daily life. As a result, people put forward higher requirements on system stability and reliability, and fault-tolerant technology has become the current Research hot spots. The full text first proposed a three-mode heterogeneous redundant fault-tolerant system architecture platform, the platform using evolutionary mechanisms to effectively build a successful individual pool, so as to ensure that the system of three redundant modules in real time when the error recovery capabilities. In order to further improve the efficiency of individual evolution in the pool of successful individuals, an interactive two-stage evaluation evolutionary strategy is introduced to evaluate the performance of the system through the evaluation of individual adaptation and individual heterogeneity. Finally, a three-bit multiplier is used as an example. The results show that the evolution strategy is evidently higher than the traditional 1 + λ evolution strategy in evolutive efficiency, and at the same time ensures the diversity of system-generated individuals and enhances the fault-tolerant performance of the platform.
