Изобретение относитс к вычислительной технике и может быть использовано в устройствах, работающих в системе остаточных классов (СОК) и в схемах контрол ЭЦВМ.The invention relates to computing and can be used in devices operating in the system of residual classes (RNS) and in the control circuit of the computer.

Цель изобретени - расширение области применени за счет возможности обработки неприведенных чисел.The purpose of the invention is to expand the scope of application due to the possibility of processing unrepresented numbers.

На чертеже представлена функциональна схема устройства дл сложени чисел по модулю три.The drawing shows the functional diagram of the device for adding modulo three numbers.

Устройство дл сложени чисел по модулю три содержит элементы И 1, 2, элементы ИЛИ-НЕ 3-11, элементы РАВНОЗНАЧНОСТЬ 12-14.A device for adding modulo three numbers contains elements AND 1, 2, elements OR NOT 3-11, elements EQUALITY 12-14.

Устройство дл сложени чисел по модулю три работает следующим образом.A device for adding modulo three numbers works as follows.

На входы устройства подаютс соответственно значени следующих разр дов операндов - аа, at, 02, bi (двоичнокодированные троичные коды чисел А и В). При этом алгоритм образовани унитарного выходного кода У1У2УЗ (результата операции) полностью определ етс приводимой таблицей истинности. Совокупности элементов И 1, ИЛИ-НЕ 3, 4, 5 и И 2, ИЛИ-НЕ 6, 7, 8 осуществл ют преобразование двоичноко- дированных троичных чисел А и В в унитарные троичные коды.The values of the following bits of the operands - aa, at, 02, bi (binary-coded ternary codes of numbers A and B) are fed to the inputs of the device. In this case, the algorithm for the formation of the unitary output code U1U2UZ (result of the operation) is completely determined by the given truth table. The sets of elements AND 1, OR-NOT 3, 4, 5 and AND 2, OR-NOT 6, 7, 8 convert the binary-coded ternary numbers A and B to unitary ternary codes.
