Description

(54) MULTIFUNCTIONAL MODULE

one

The invention relates to the field of computer technology and is intended to implement all logical formulas in a basis of five or less letters,

Known multifunctional modules that implement by setting logical formulas.

However, these modules do not allow to implement by tuning all logical formulas in the basis of 6, V,. from a large number of letters, for example from pi 1 and 2,

The closest technical re-. The proposed solution is a multifunctional module containing AND and OR elements, logical inputs and two logical outputs, which can be realized by setting up (connecting some inputs of the module to the power buses or to each other) to implement some of the common logical formulas in basis 6, V of 8 and less letters 3.

The disadvantage of the module is a large number of external leads and low manufacturability.

The purpose of the invention is to increase the reliability of the manufacturability of the module.

The goal is achieved by the fact that the module contains three logical blocks, Each of which contains two OR elements and two K elements, with the output of the first OR element in each logical block connected to the first output of the first AND element, the output of which is connected to the first input of the second OR element , output

10 of which is connected to the output of the logic unit, and the second input of which is connected to the output of the second element AND, the first, second and third inputs of which are connected respectively with the first, second and third inputs of the first OR element and with the first, second and third inputs of the logic unit, the fourth input of which is connected to the second input of the first element AND, the first, second and third inputs of the first logic block are connected respectively to the fourth, second and third inputs of the second logical block and to the first, second

25 and the third logical inputs of the module, the fourth. Input of the first logical block is connected to the first input of the second logical block and to the output of the third logical block, first, 30 second and third and fourth inputs

Which is connected to the fourth, the fifth, and the external and the seventh logical inputs of the module, respectively, the outputs of the first and second logical blocks are connected respectively to the first and second logical outputs of the module.

FIG. 1 shows the structural scheme of the multifunctional module; in fig. 2 is a logic block diagram.

The device contains logical inputs of module 1, 2, 3, 4, 5, bi7, logical blocks 8, logical inputs of logical blocks 9, 10, 11 and 12, outputs of logical blocks 13, logical outputs of module 14 and 15, elements:; - you are 16 and 17 AND, elements 18 and 19 OR in a logical block.

The module structure is described by the following functions:

letters Thus, the proposed multi-functional module has 9 external outputs (7 inputs and 2 outputs) and implements by customizing any of 24 representatives of 6iecnoBopOTHHX formulas In a five-letter basis. The reduction in the number of external logical conclusions (9 instead of 12) leads to an increase in the reliability of the proposed device relative to the known when implementing formulas from the specified number of letters. The proposed module has a more homogeneous structure. in comparison with the well-known one, since it is implemented on three modules of the same type, which leads to its technological effectiveness. A multifunctional module containing AND and OR elements, logical inputs, two logical outputs, characterized in that, in order to increase the reliability and technology of the module, it contains three logical blocks, each of which contains two OR elements and two elec And, in each logical block, the output of the first OR element is connected to the first input of the first And element, the output of which is connected to the first input of the second OR element, the output of which is connected to the output of the logic unit, and the second input fti Pf is connected to the output of the second element AND, the first, second and third inputs of which are connected respectively to the first, second and third inputs of the first OR element and to the first, second and third inputs of the logic unit, the fourth input of which is connected to the second input of the first AND element, the first, second and third inputs of the first logical block are connected respectively to the fourth, second and third inputs of the second logical block and to the first. The second and third logical inputs of the module, the fourth input of the first logical p block is connected to the first input of the second logical block and to the output of the third logical block, the first, second, third and fourth inputs of which are connected to the fourth, fifth, sixth and seventh logical inputs respectively module, the outputs of the first and second logical blocks are connected respectively to the first and second logical outputs of the module.
