Abstract

The invention relates to the field of measurement technology and can be used to create instruments with a light scale and in information recording systems on a photosensitive medium. The aim of the invention is to increase the speed and reliability of the device. The device contains the first code converter 1, the registration unit 2, the second code converter 3, the first 4 and the second 5 encoders. The goal is achieved by converting the input information with the help of code converters and encoders into a code that allows the registration unit with a smaller number of elements to be used to register the input information while increasing the size of the input codes. 2 Il.

The invention relates to a measurement technique and can be used to create instruments with a light scale and in information recording systems on a photosensitive medium.

The purpose of the invention is to increase the speed and reliability of the device.

 Figure 1 shows the functional diagram of the device; 2 shows an example of a specific implementation of the device for the case of outputting a three-bit code;

The device (figure 1) contains the first Converter 1 code, block 2 registration, the second Converter 3 code, the first 4 and second 5 encoders.

Additionally, in Fig. 1, the positions 1 ... m-1 denote the inputs of the device, the positions 1 ... n, n + 1, n + 2 ... p are the inputs of the registration block, where p is the number of registration elements of the block 2 , etc.

The device (figure 2) contains the first Converter 1 code, block 2 registration, the second Converter code 3, the first 4 and second 5 encoders, the first 6, second 7, third 8 and fourth 9 elements OR, first 10, second 11, third 12 and the fourth 13 elements I.

The operation of the device is considered on the example of outputting the numbers 1 i p and p j p. To output the numbers i to the inputs of the device, its code equivalent is supplied, including the potential O to its to-th input and, therefore, to the control inputs of encoders 4 and 5 and (n + 1) -th input of block 2. As a result of the potential U acting on the control inputs of the encoders 4, 5, the code equivalent of the number 0 is applied to the inputs of the converter 3 of the code, which is converted into (pn-1) -discharge code combination 00 ... O, and the inputs of the converter 1 The code that arrives at the inputs of the device from 1 to K-1 is received. This code is transformed by the converter 1 into the n-bit code combination 0 ... 011 ... 1, containing i units. As a result, at the inputs of block 2, a p-bit code 00 ... 011 ... 1 is set, containing i units, which leads to the excitation of i elements of block 2.

To output the number j to the inputs of the device, its code equivalent is supplied, incl. potential 1 to its k-and input, and, therefore, to the control inputs of the encoders 4, 5 and (nf 1) -th input of block 2. As a result of the potential 1 on the control inputs

encoders 4, 5, the inputs of converter 1 are supplied with the code equivalent of the number n, transformed into an n-bit code combination 11 ... 1, and the inputs of converter 3 are installed with the code installed on the first m inputs of the device. The latter is transformed into a (pp-1) -discharge code combination of the form 00 ... 011 ... 1, containing (j-n-) units. As a result, at the inputs of block 2

sets the p-bit of the code combination 00 ... 011 ... 1, containing j units, which leads to the excitation of j elements of block 2.

Example. Output device

information at 3 and p 8 is shown in figure 2. The device contains 4 two-input AND logic gates and 4 two-input OR gates. Unit 2 contains 8 LEDs with drive current driver. The information to the input of the device is supplied in the form of a three-bit binary normal code (r 3). The number of logical elements required for the technical implementation of the claimed device, Zz 8. The number of logical elements required for the implementation of the prototype, Sn 18.

Thus, the number of logical elements necessary to build

devices, more than 2 times less than in the case of the prototype. The size of the device can be increased by combining similar blocks (Fig. 2).
