Synthesis of symmetric functions based on RM type universal logic module ULM3

阐述了基本RM型对称函数的定义和性质,给出了任意n变量对称函数在n-1变量基本RM型对称函数完备集中展开系数的计算公式,在此基础上,提出了基于RM型三变量通用逻辑门ULM3的变量数为奇数或偶数的对称函数综合方法,实例验证了上述方法的有效性.

The definition and properties of basic RM type symmetric function are introduced, the formula of calculating the expansion coefficients of an arbitrary n variable symmetric function in the complete set of n-1 variable basic RM type symmetric functions is given. Based upon it, the synthesis method of the symmetric function with odd and even number of variables by using RM type universal logic modules ULM3 is proposed. The practical examples prove the effectiveness of the synthesis method presented in the paper.
