(54) CONVERTER CODES COORDINATES INTO A SINGLE CODE

The invention relates to automation and computing code (it can be used to build software in computing and control systems. A code converter is known which consists of serially connected decoders and encoders. A disadvantage of the known device is the impossibility of converting the coordinate codes into a single code. The closest to the invention to the technical essence is a code converter containing a decoder 2. The disadvantage of this converter lies in the lack of the ability to convert coordinate codes to direct and inverse unit codes. The purpose of the invention is to expand the functional possibilities of converting coordinate codes to both forward and reverse unit codes. The goal is achieved by converting the coordinate codes to a single code The descrambler contains additional descrambler and n transfer units, where n is the number of bits of the output code, the information outputs of the transfer units are the outputs of the converter, the control inputs to ex transfer blocks are connected to the input of the attribute of the converter, the transfer output of the 1st (t-1 ... (p-1) transfer unit is connected to the transfer input of the (1 + 1) -th transfer unit, transfer output of the n-th block the transfer is connected to the transfer input of the first transfer unit, the first information input of the 1st transfer unit is connected to the 1st output of the deifurator, the second information input} of the transfer unit is connected to the (nl) -H output of the inverting decoder, the inputs of the decoder and the inverting decoder are The CTBeliHO inputs of the start and end codes and

elements of the converter ring, and also the fact that the transfer unit contains two elements AND, two elements IL and an element whose first input is controllable to the input of the transfer unit and connected to the first input of the first element AND, the second input of the element OR NOT. connected to the output of the first SHI element, which is the transfer output of the transfer unit, and to the second input of the first element AND, the output of which is connected to the first input of the second OR element, the second input of which is connected to the output of the OR-NOT element, and the output of the second SHSh element is inf The output of the transfer unit, the first input of the first SHS element is the first information input of the transfer unit, the second input of the first OR element is connected to the output of the second AND element, the first input of which is the transfer input of the transfer unit, and the second input is the second information input of the transfer unit . .

The converter converts the codes of the coordinates of the ring elements to a unit code.

The coordinate codes of the elements of the Ring are understood to be the codes encoded by any code (1,2 ..-. "And) of the elements of the beginning and end of subsets of B units or zeros of C belonging to the set of elements of ring A and subject to the following conditions:

 - | H2 - C1i; V.Cs: A; Aiis; 90C, vf,, ecli c-OjoB A.

The set of elements of ring A is a unit code of a ring type with a sliding element of origin, where element A is the next for A. Set A can be represented in a forward unit Rim inverse unit code depending on the sign of belonging to indices D, which determines which from the subsets (to or C) belong to the beginning and the end indices. This makes it possible to define in the simplest way two disjoint subsets, from the entire set of consecutive ring elements. bordering among themselves and consisting also of successive elements

A new operation is the operation of assigning subsets B and C by

Coordinate codes of the elements of the beginning and end with the propagation of the transfer from the first to the second, including all intermediate elements.

The drawing shows a block diagram of a converter of the codes of the coordinates of the elements of a ring into a single code.

The code converter contains a decoder 1, a decryption index of an element of the beginning of a selected subset, represented by any t-bit code, an inverting decoder 2, a decryption index of an element of the end of a selected subset, represented by any t-bit code, and an encoder 3, consisting of AND - identical transfer blocks 4 encoding the codes of the indices of the elements of the beginning and the end chosen depending on the attribute of belonging: the index D of the single or zero subset, to the forward or reverse single code. The decoder has m inputs 5 (5, 5 ,,., ,, 5y,), and decoder 2 has m inputs 6 (b, 6,2, ... 6), which are in failure, are the inputs of the code converter. Decoder 1 has n outputs 7 (7, 72, .... 7) o Deshfrato 2 has n outputs 8 (8, 3 ,,, 8y,}.) The control inputs 9 of all transfer blocks 4 are interconnected and are input 10 of the encoder 3. This is input 0, which in turn is the input 11 of the sign of belonging of the indexes D of the converter of the code Converter input 12 of the unit 4 of the encoder 3 Connected: to output 13 of the transfer (K-1) of the fourth unit 4 of the encoder 3. Information input 14 of the K-th block 4 transfer, vl yush; IC input 5 | encoder 3, connected to (K-1) -m output 8 (inverting decoder 2. Information input 16 of the K-th transfer unit 4, The input 17K of the encoder 3 is connected to the output 7K of the decoder 1. The information output 18 of the K-th transfer unit 4 is the output 19K of the encoder 3. This output 19K of the encoder 3, in turn, is the information output 20K code converter. The output 13 of the transfer of the K-th transfer unit 4 of the encoder 3 is connected to the input 12 (K + 1) -g of the transfer unit 4 of the encoder 3.

Block 4 of the transfer of the encoder 3 contains the elements And 21-22, elements OR 23-24, the element W-NOT 25.

The converter of the codes of the coordinates of the elements of a ring into a single code works as follows.

The information on the index of the elements of the beginning and end of the selected subset, presented in a convenient code, is fed to the inputs 5 and 6 of subscriber 1 and 2, and the signal corresponding to the selected subset is input to the input 11 of the code converter for the subset units in, and for subsets of zeros. Decoders 1 and 2 decode the input codes, the decoder 5 being in direct code (1 - to: outputs 7, and decoder 2 V. the inverse code - to outputs 8. This information goes to inputs 15 and 17 of encoder 3, where it is The code is encoded into a single code represented at the outputs of the converter 20, where the origin of the reference is taken from the output of the element whose coordinate was specified by the code on the inputs 5 of the converter code. A unit in one of the bits of the code represented at the outputs 7 of the decoder I, arrives at the corresponding input 16 of block 4 of the encoder 3 and, independently of t signal on

the output of the element 21, forms the output of the element OR 23 Unit, which, depending on the state of input 9 of block 4 of the transfer of the encoder 3 (sign of belonging indexes O, input 11 of the code converter). forms through the elements AND 22, BL-HE 25, OR 24 the corresponding signal at the output 20 of this bit of the code converter, also forms the Transfer Unit to the next bit. The transfer through AND 21 elements to ISH 23 after the blocks 4 of pinfrarator 3 propagates until Zero in one of the bits represented outputs 8 decoder 2 post drunk on the corresponding input 14 of block 4 of transfer of the encoder 3, will not prohibit the element I 21. In all

through which the unit of the transference passed.

Depending on the signal at the input 9 of the block 4, the encoder 3 (the indication of the belonging of the indices D) at the inputs 20 of the code converter appears Units or Zeros.

The operation of the encoder 3 is additionally explained in the truth table, compiled for the case of a 4-bit DNA recorder. ,
