Abstract

Boolean equations are important tools in digital logic. Previous algorithms for solving Boolean equations are based on the Boolean algebra of disjoint SOP forms. In this paper, we develop a new Boolean algebra with more efficient Boolean operation algorithms, called the reduced ordered SOP (ROSOP) forms, which are canonical representations. ROSOPs are closely related to the well-known OBDD data structure. The results here also show the algebraic structure of OBDDs.
