Изобретение относитс к вычислительной технике и может использоватьс при построении различных узлов и устройств ЭВМ.The invention relates to computing and can be used in the construction of various components and computer devices.

Известен управл емый арифметический модуль, содержащий триггер, элементы И,ИЛИ и НЕ, управл ющие и информационные входы и выходы, и предназначенный дл арифметической и логической обработки двоичных чисел, и хранени и сдвигов 1 A controlled arithmetic module is known, containing a trigger, AND, OR, and NOT elements, controlling and informational inputs and outputs, and intended for arithmetic and logical processing of binary numbers, and storage and shifts 1

Однако функциональна ограниченность и сложность этого устройства не позвол ют реализовать в нем выполнение операций над обратными кодами операндов.However, the functional limitations and complexity of this device do not allow it to perform operations on the reverse codes of operands.

Наиболее близким техническим решением к изобрета.шю вл етс управл емый арифметический модуль,. содержащий элементы И, ИЛИ,триггер, причем перЬые входы первого и второго элементов И соединены между собой и вл ютс входом переноса модул , первый вход третьего элемента И соединен с вторым входом второго элемента И, а второй вход третьего элемента И вл етс входом управлени сложением модул , выходы первого и второго элементов И соединены с входами элемента ИЛИ, выход которогоThe closest technical solution to the invention is a controlled arithmetic unit. containing the elements AND, OR, a trigger, the first inputs of the first and second elements AND are interconnected and are the transfer input of the module, the first input of the third element AND is connected to the second input of the second element AND, and the second input of the third element AND is the input of the addition module, the outputs of the first and second elements And are connected to the inputs of the element OR, the output of which

вл етс выходом переноса модул 2. Модуль содержит кроме того элементы НЕ.is the output of the transfer module 2. The module also contains the elements NOT.

Целью изобретени вл етс расширение функциональных возможностей за счет выполнени сложени чисел в обратном коде.The aim of the invention is to enhance the functionality by performing the addition of numbers in the reverse code.

Достигаетс это тем, что в модуль введены два коммутатора и два элемен0 та равнозначность, причем управл ющие входы первого коммутатора, первые входы первого и второго элементов равнозначность , информационные входы второго коммутатора вл ютс управ5 л ющими входами модул , информационные входы первого коммутатора вл ютс информационными входами модул , вторые входы первого и второго элементов равнозначность соединенных This is achieved by the fact that two commutators and two equivalence elements are introduced into the module, the control inputs of the first switch, the first inputs of the first and second equipotential elements, the information inputs of the second switch, the information inputs of the first switch are information the inputs of the module, the second inputs of the first and second elements are the equivalence of the connected

5 by the third inputs of the second element I and with the control inputs of the second switch, the output of which is connected to the second input of the first element I, and its output is connected.) 1 to the switch of the BTOIXH-O switch connected to the quarter-input of the third element And is the input to the module. The device shown in the drawing. It contains switches 1 and 2, element OR 3, trigger 4, elements AND 5.6 and 7, elements of equivalence 8 and 9. The output of the first switch is denoted by 10, the information inputs of module 11-14, the output of module 15, the transfer output 16, control inputs of the module G7-26. Managed arithmetic module works as follows. The information inputs 11-14 of the device are given signals from the high-order output of the S-row, from the low-end output of S., the operand-x discharge, transfer from the low-order P,. From the output of module 15, the output signal 5 is output or a stored operand, and from output 16, a skew signal P from the given bit. The signals and and U / j at the inputs 17 and 18 of the module control the passage of signals 5., x. , S to the input of the module for further processing. The signal and the input to the module input 19 controls the inversion of the signals taken from the Velohd of switch 1, while if U, j 1, the signal is not inverted, and if 0, it is inverted. Signal Ud. at the input 20, the module allows the formation of the transfer signal P. Signals Beats. The Ug supplied to the control inputs of the module 21-24 define a logical function of two variables, implemented using switch 2 and corresponding to the operation performed in the device. The signal Ug at the input 25 of the module controls the inversion of the signal S when it is fed to the input of switch 2 as the signal of the 1st operand. The module circuit, when performing any of the functions determined by the tuning signals and - Ug, works only when the pulse input signal is applied to the control input of the module 26.
