FORWARD HIGH-ORDER-POSITION ADDERSUBSTRACTOR BUILT AROUND NEURONS Russian patent published in 2003 - IPC

FIELD: computer engineering. SUBSTANCE: device can be used for synthesizing arithmetic and logical units, and developing high- speed economically efficient digital devices for adding and subtracting true form numbers. Adder-subtract or functions to add and subtract binary numbers. Addition is carried out if these binary numbers have same sign. Otherwise modulo lower number fewer is subtracted from modulo higher number. Sign of result is sign of higher number. Neuron and threshold logic elements and majority elements are used in device that functions to effect forward high-order position addition and subtraction. EFFECT: simplified design of arithmetic and logical unit; enhanced reliability of device, simplified algorithm of its control unit. 1 cl, 10 dwg
