在线演化系统容错机制的研究
|
摘要
为改善数字电路系统的容错能力,提高其可靠性,提出了在线补偿容错系统设计方案。在基于演化硬件技术所构建的演化平台基础上,新增虚拟可重构电路模块对故障电路进行演化补偿,实现补偿容错;针对电路中可预见的故障提前进行演化,建立故障匹配库;对不可预见的随机故障进行实时演化,并对故障匹配库进行扩充,当再次出现同样故障时,可直接在故障匹配库中寻找解决方案。实验结果表明,该容错系统能以较少的资源占用获得较好的容错性能,提高了在线演化的可靠性。
To improve the fault-tolerant capacity and the reliability of electronic systems,a design scheme about compensation and fault-tolerant system is given.On the basis of the evolution platform which is based on the evolvable hardware technology,a new virtual reconfigurable circuit is added to implement compensation fault tolerance.Evolve circuit with foreseeable common faults and then establish fault matching library;Real-time evolution of unforeseen random faults and expand the library;find the solution directly in the fault matching library when the same failure occurs again.The experimental results show that the system can obtain better fault-tolerant performance at the cost of the smaller redundant and improve reliability of online evolution.
