Abstract

The invention relates to automation and computing and is intended to implement all the non-repetitive functions of the three arguments by adjusting the signals from the set {0,1}. The purpose of the invention is to increase the number of realizable non-repetitive functions of three variables. This goal is achieved by the fact that the module contains three information, five tuning inputs, two AND elements, four elements COMPONENT BY MODULE TWO and one output. 1 tab., 1 Il.

Description

The invention relates to automation and computing and is intended to implement non-repetitive functions of three variables.

The aim of the invention is to increase the number of realizable non-repetitive functions of three sweeps.

The drawing shows the functional diagram of the module.

The scheme contains elements 1 and 2, elements ADDITION ON MODULE TWO groups 3 - 5, configuration inputs of module 6-8, information inputs 9-11 module, element COMPONENT ON MODULE TWO 12, configuration inputs 13 and 14 module, output 15 module.

The operation of the module is described by the expression

f (x77X}) (u, ®xp (Ui®x) (Ujex,) ®

@ U4X, ® Uj,

where f (X, X) is non-repetitive

three variable function;

X, X - informational arguments;

, i}

1 1.5 - setting arguments.

Multifunctional logic module operates as follows.

To implement one of the 32 non-repetitive functions of the three variables, it is necessary to configure the inputs of the 6-8 module, 14 and 13 to submit the appropriate setting signals according to the table. Information inputs 9-11 of the module are given information arguments, respectively. In this case, through the time determined by the depth of the circuit, At the output 15 of the module, the necessary function is realized. Thus, multifunctional
