MODULO SEVEN ARITHMETIC UNIT Russian patent published in 2022 - IPC G06F7/72 

FIELD: computing technology.

SUBSTANCE: invention relates to a modulo seven arithmetic device. The device contains twelve elements EXCLUSIVE OR, and the second inputs of the fourth, fifth, sixth and eighth, ninth, tenth elements EXCLUSIVE OR are connected respectively to the outputs of the second, third, fifth and fourth, sixth, eleventh elements EXCLUSIVE OR, and the first input of the seventh, second input of the k-th and the output of the (6+k)th elements EXCLUSIVE OR are connected respectively to the output of the first element EXCLUSIVE OR, (3+k)th input and k-th output of the modulo seven arithmetic device, at the same time, two elements EXCLUSIVE OR and eight elements PROHIBITION are additionally introduced into it, the first, second inputs of the eleventh and first, second inputs of the i-th elements EXCLUSIVE OR connected respectively to the outputs of the fifth, third and non-inverting, inverting inputs of the i-th elements PROHIBITION, the first, second inputs of the seventh and first, second inputs of the eighth elements EXCLUSIVE OR connected respectively to the inverting, non-inverting inputs of the seventh and non-inverting, inverting inputs of the eighth elements PROHIBITION, the first inputs of the fourth, fifth, sixth and the eighth, ninth, the tenth elements EXCLUSIVE OR are connected respectively to the outputs of the first, second, fourth and seventh, eighth, sixth elements PROHIBITION, and the output of the tenth, the first input of the k-th, the first and second inputs (11+k)-th elements EXCLUSIVE OR are connected respectively to the second input of the seventh, the output of the (11+k)-th elements EXCLUSIVE OR, the tuning and k-th inputs of the modulo seven arithmetic device.

EFFECT: providing the ability to perform several types of modulo seven arithmetic operations.
