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

FIELD: computer engineering. SUBSTANCE: device has two modulo-two adders, majority element with threshold of two, majority element with threshold of four, two NOT gates, five AND gates, four NOR gates, six information inputs, seven setting inputs, one 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
