DEVICE FOR FUZZY COMPUTING Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: device has two registers 1 and 2, two NOT-EQUAL gates 3 and 4, commutator 5 and 6, direct-to-complement code converters 7, 8, 10, adder 9, NOT gate 11, group n of AND gates C₁= A+B, C₂= A-B, C₃= B-A, C₄= A+B, C₅= A-B, C₆= B-A, group of n AND gates I₁= min(1,1-A+B) (where n is bit length of operands), commutator 14, data inputs 15 and 16, data write permission input 17, control inputs 18-21, result sign output 22, result output 23, result absolute value output 24, logical operations result output 25. In addition to possibility of implementation of fuzzy functions I₂= min(1,1-B+A), device implements such fuzzy logic functions as disjunction D min (1, A+B), implication 12₁-12_n min (1, 1-A+B), implication 13₁-13_n min( 1, 1-B+A), Sheffer stroke symbol S min( 1, 1-A+1-B), difference Q max (0, A-B), conjunction K max( 0, A+B-1), Pierce's arrow P max(0, 1-A-B). EFFECT: increased functional capabilities. 1 dwg
