Предлагается теория, связывающая булеву и частичную алгебры, позволяющая построить новые представления и разложения частично определенных функций. Замечательным свойством разложений является сокращение степени определенности продуктов разложения, что служит источником расширения возможностей при решении задач синтеза, распараллеливания и оптимизации полностью и частично определенных логических программно-аппаратных систем. Результатом предложенной теории является новый тип двоичных диаграмм решений. На примере распараллеливания сумматоров показано значительное увеличение быстродействия системы при незначительном увеличении ее сложности.</p></abstract><trans-abstract xml:lang="en"><p>The well known Shannon expansion is not applicable to incompletely specified functions. We propose a theory that merges Boolean and partial algebras and provides creation of new representations and expansions of partially specified functions. A powerful property of the expansions is the reduction of definiteness level of expansion products. This is a source of enlargement of possibilities for synthesis, parallelization and optimization of completely and incompletely specified logical software/hardware systems. A result of proposed theory is a new type of decision diagram. It is shown on the parallelization of adders that the throughput of the system grows rapidly while the system complexity grows slowly.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>: не полностью определенная функция</kwd><kwd>частичная логика</kwd><kwd>разложение</kwd><kwd>диаграмма решений</kwd><kwd>оптимизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>incompletely specified function</kwd><kwd>partial logic</kwd><kwd>expansion</kwd><kwd>decision diagram</kwd><kwd>optimization</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Prihozhy, A.A.
