(eng): We propose a simple and fast two-level minimization algorithm for completely specified functions in this paper. The algorithm is based on processing ternary trees. A ternary tree is proposed as a structure enabling a very compact representation of completely specified Boolean functions. The minimization algorithm is thus most suited for functions described by many on-set terms. When these functions are to be minimized, most of the state-of-the-art minimizers (Espresso) need prohibitively long time to process them, or they are even completely unusable, due to their very high memory consumption. Our algorithm is able to minimize such functions in a reasonable time, though the result quality does not reach the quality of other minimizers. Here our minimizer found its application as a pre-processor that, when run prior to, e.g., Espresso, significantly reduces total minimization time, while fully retaining the result quality.
