ARITHMETIC-LOGICAL DEVICE FOR SUMMING NUMBERS TO MODULE Russian patent published in 2017 - IPC G06F7/52 

FIELD: physics.

SUBSTANCE: device contains n-bit registers, electronic keys, an inverter, an n-bit adder, an OR disconnect circuit, a control unit module, an input and output bus. The method provides subtraction of the number B from A to module P. The operands are the numbers A and B, which are in the range of 0 to (P-1) inclusive. The minuend, subtrahend and the module from the input bus are written into the registers. The subtraction operation is performed by summing the minuend in the forward code with the subtrahend in the additional code. If the difference of the numbers S=(A-B) is nonnegative, then the cast operation to module is not executed, and the result of the subtraction (A-B) to module P is the difference (A-B). If (A-B)<0, then the value of the module P is added to this difference, and the result is the result of the device operation.

EFFECT: expanding the arsenal of funds by providing the summation of numbers exactly to module.
