BINARY NUMBER COMPARATOR Russian patent published in 2007 - IPC G06F7/02 

FIELD: computer engineering, possible use for building automatic devices, functional units of control systems, etc.

SUBSTANCE: binary number comparator contains OR logical element, OR-NOT logical element and two XOR logical elements, three AND-NOT logical elements. First input and output of i XOR logical element are connected respectively to first and second inputs of i AND-NOT logical element, connected by second input to i input of OR-NOT logical element. First, second inputs and output of OR logical element are connected respectively to output of second, by second input of first logical element AND-NOT and second input of third logical element AND-NOT, connected by first input and output respectively to output of first logical element AND-NOT and to first output of binary number comparator, second output and i, (i+2) inputs of which are connected respectively to output of logical element OR-NOT and first, second inputs of i XOR logical element.

EFFECT: decreased hardware resource costs with preserved functional capabilities and speed of operation.
