Description

The invention relates to automation and computing and is intended to create high-speed devices when implementing non-repeating Boolean functions of four variables.

The purpose of the invention is to increase speed.

The drawing shows the function. The circuit of the multifunctional logic module.

The multifunctional logic module contains information inputs 1-4, configuration inputs 5-7, outputs 8 and 9, elements AND 10-17, element OR 18, elements NOT 19 and 20.

Multifunction logic module works as follows.
