摘要: 本文运用两变量沃尔什-阿达马变换分析了一般多输出组合逻辑系统因软故障引起的系 统错误概率,导出了计算某些特殊情况及常用的SUM-OF-PRODUCT和NAND-NAND系统错 误概率的简化公式和快速算法.利用计算机研究了几个实例,它们揭示了由软故障引起的系 统错误概率的特征,为设计多输入多输出组合逻辑系统,降低软故障对系统的影响,提供了有 益的启示.Abstract: Using two dimensional Walsh-Hadamard Transform performance of probability of errors caused by soft noise for general multiple output combinational logic systems is analyzed. Simplified equations and a fast new algorithm for computing the probability of errors caused by soft noise to some specific cases and the general case, the SUM-of-PRODUCT and NAND-NAND model are obtained. Several examples has been considered by the use of computer codes. It reveals the characteristics of the probability of errors caused by soft noise and provides some useful prompt for the design of multiple output combinational logic systems.
