【摘要】：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。
[Abstract]:With the rapid development of electronic technology, the miniaturization and intelligence of electronic products make them become an important part of people's daily life, so people put forward higher requirements for the stability and reliability of the system. Fault-tolerant technology has become a hot research topic. Firstly, a ternary heterogeneous redundant fault-tolerant system architecture platform is proposed, which utilizes evolution mechanism to effectively construct successful individual pool. In order to further improve the efficiency of generating evolutionary individuals in the successful individual pool, an interactive two-stage evolutionary evaluation strategy is introduced to ensure the real-time repair capability of the three redundant modules in the system. The system performance is improved from two aspects of individual fitness and heterogeneity. Finally, a three-bit multiplier is used as an example. The results show that the evolutionary efficiency of the evolutionary strategy is obviously higher than that of the traditional 1 位 evolution strategy. At the same time, it ensures the diversity of system generator and enhances the fault-tolerant performance of the platform.
