DEVICE FOR COMPARING BINARY NUMBERS Russian patent published in 2025 - IPC G06F7/02 

FIELD: computer equipment.

SUBSTANCE: device for comparing binary numbers is intended for recognition of ratios X>Y, X=Y, X<Y, where X, Y are n-bit binary numbers set by binary signals, and can be used in digital computer systems as a comparator information processing means. Device for comparing binary numbers comprises 2×n implicators (1₁₁, 1₂₁, …, 1_1n, 1_2n) and 4×n-4 NAND elements (2₁₂, 2₂₂, 2₃₂, 2₄₂, …, 2_1n, 2_2n, 2_3n, 2_4n). Due to the said elements connection new scheme, which price according to Quine is equal to 14×n-8, the maximum signal propagation delay time in the disclosed device is determined by the expression τ=(2×n-1)×τ_E, where τ_E is the duration of the delay introduced by the logic element.

EFFECT: faster operation while preserving functional capabilities and Quine price of the prototype.
