Description

The invention relates to automation and computer technology and can be used to implement all non-repetitive logical formulas of four or less letters as part of a logical control system.

The purpose of the invention is to simplify the module.

Functional diagram of the module is shown in the drawing. The following designations are accepted: information inputs 1-4, configuration inputs 5-8, elements OR 9-12, elements AND 13-16, element UNEMINABILITY 17, output 18 module

The module structure is described by a Boolean function of eight variables:

f (2 | {YYMY26) Y (24U z3) (ZiVz5). V z ,, zfz6V (ztVz5)) © zg.

The operation of the module in various tuning modes for implementing all types of non-repetitive logic functions of four variables with equal availability of direct and inverse outputs of information sources and, if possible, permutations of the input variables is illustrated in the table.

Example. Let it be required to implement a non-repetitive logical function of the type (2 + 1) 1, i.e. f (V z) which corresponds to row b of the table.

Signals z {, z2, z, z, respectively, are fed to inputs 1-4 of the module, and signals of Log.O. are input to inputs 5-8. The realizable function f is removed from the output 18 of the module.

Similarly, any non-repetitive logical, function of four variables can be implemented.

Thus, the module allows to realize by tuning all non-repetitive logical functions of four or less variables.
