Paper Abstract

An efficient spectral algorithm for representing any Boolean function as a linear combination of positive Boolean functions (PBF) is proposed. A processor architecture realizing this algorithm with the varying levels of parallelism is suggested. The algorithm finds not only the truth table of PBF's, but also their minimal disjunctive normal form representations. This allows to incorporate previously proposed efficient stack filtering designs into the construction of architectures for threshold Boolean filters.
