DEVICE FOR CALCULATION OF SYMMETRICAL BOOLEAN FUNCTIONS Russian patent published in 1995 - IPC

FIELD: computer engineering and microelectronics. SUBSTANCE: device has OR gate, majority element with threshold of three, majority element with threshold of five, modulo-two adder, two NOR gates, five inhibition gates, AND gate, six information inputs, seven setting inputs, output. Device operates as follows. Binary variables X₁-X₆ are received by inputs in arbitrary order. Setting inputs receive tuning signals U₁-U₇ which values belong to set0, 1} A symmetric boolean function F= is generated at output. This function is determined by setting vector U = (U₁, U₂,...U₆). EFFECT: increased functional capabilities, simplified design, increased speed. 1 dwg
