纳米电路交叉冗余容错技术研究

提出了一种针对纳米电路的数字电路容错设计新方法.该方法基于交叉冗余原理,利用两种二进制错误的不对称性,采用模块化方法对纳米电路进行容错设计.以阵列乘法器为例,采用新方法对电路进行设计和仿真,并结合实验结果与传统的可重构和三模冗余容错方法进行比较.交叉冗余方法无需检测模块及表决器,不会增加系统延时,并且在资源消耗方面远低于传统方法,对纳米电路尤其适用.

Research on Fault-tolerant Techniques Based on Interwoven Redundancy for Nanoscale Circuits

A new method for designing fault-tolerant digital circuits to reduce the failure rate of nanoscale circuits based on interwoven redundancy and the asymmetric of two kinds of binary errors,using a modular approach to design circuits.With multiplier as an example,this paper conducted a simulation experiment using the new method.The results show that it is better than the traditional fault-tolerant design methods.The new method is especially suitable for nano-circuits because it won't increase the system delay...
