摘要
根据对称函数的性质,在对称函数K图/bj图的基础上提出了部分对称函数/全对称函数的dj图表示.给出了利用对称函数dj图检测对称性的方法,并以实例加以说明.与传统方法相比,该法使基于逻辑函数对称性的逻辑设计较传统设计更简单、更有效.
Symmetry is a significant property of a logic function. However, the conventional methods of detecting symmetry of a logic function are too complicated if the function is expanded to CRM in OR COINCIDENCE algebraic system. According to the property of symmetric function, the denotation about dj map of partially symmetric funcion and totally symmetric function was presented based on the K-map of symmetric function and bj map of symmetric function. Symmetry of the function can be detected by means of dj map of symmetric function, and some examples were given. The method has several advantages that the logic design based on the symmetry of logic function is simpler and more effective as compared with conventional design.
