Abstract
This paper presents a minimization algorithm for fixed polarity dual Reed-Muller expressions (FPDRMs) for completely specified functions. For an n-variable function there are 2 '' different distinct FPDRMs. Minimum FPDRMs is one with the fewest number of sums. The minimization algorithm for the two-level dual Reed-Muller expressions has been developed, based on a four set of rules. The four new linking rules have been introduced to minimize single output dual Reed-Muller (OR/XNOR) expressions. The new rules are demonstrated using Karnaugh maps for some random functions.
