FIELD: information technologies.
SUBSTANCE: invention is related to computer engineering and may be used as a specialised calculator of Boolean functions systems. Goal defined is achieved due to provision of calculation of not the whole system of Boolean functions, represented in modular numerical normal form, but just one system of subfunctions, represented in modular numerical normal form, obtained as a result of decomposition applied to system of Boolean functions. Device comprises commutator, unit of conjunctions, 2k memory units, where k is number of Boolean decomposition variables, 2n-k multiplexers, summator.
EFFECT: reduced duration of calculations.
