VHK - the input channel is used to receive data.

BOP - the block of random access memory serves for temporary storage of the accepted word or number.

ES - an element for comparing the characters of a received word and already ordered words or patterns.

SBP2 - the second stacked memory block serves to store part of an ordered array and organize ordering, as well as to store a processed fragment of text.

SBP1 - the first stacked memory block is used to store part of an ordered array and organize ordering or storage of an array of samples in the selection mode, or samples and substitutions in the substitution mode.

The theory of normal algorithms is universal with respect to any algorithmic schemes [1]. A Markov algorithm is a finite sequence of formulas of the form

where S is the sample; T is a substitution; S and T are arbitrary words in a fixed alphabet.

The formula works by detecting a fragment in the word that matches the pattern and replacing the detected fragment with a substitution word.

The ordering of words, for example, on the basis of alphabetical order in the theory of normal algorithms, occupies a special place, since it relates to difficult tasks in which formulas (products) are used that contain patterns with operations specified in their structure. In this case, we are talking about the operation of comparing "more", "less" and "equal". Substitution in formulas of the form (1) also has its own specifics and is an auxiliary service word that indicates the position of a word among other words in a given ordering rule, and for word selection this service word is an index of a word that meets specified selection rules. To implement the selection of words with substitution, products of the form (1) are used.

The proposed device is based on a modified algorithm that contains a sample and a substitution with the above features. The information sorting device implements formulas of the form (2, 3, 4)

S1, S2 - sample comparands; © - a symbol denoting the operation of comparing to "more", "less" and "equal"; © '- a symbol indicating the operation of comparing by “more” and “less” with “equal”, taking into account the mask of the sample when matching (which is shown as the sample compend in the formula of the form (1)), as well as comparing the length of the companions; T1 - position indicator in a partially ordered array of one of the comparands depending on the result of the comparation or comparison of word lengths; T2 - pointer to the next (current) companion or sample construction rule based on the results of word comparison; → - separators in the form of service characters that are not included in the main alphabet; T3 - fragment substitution, which means the issuance of the received word on the output channel.

n is the number of samples; S3 - many samples; T4 - many permutations; i is the number of the sample and its corresponding substitution.

In the proposed device, the meaning of the substitution fragment T2 is to receive the next character from the input channel.

A formula of the form (2) defines a recursive implementation of the ordering process; a formula of the form (3) is a selection process, a formula of the form (4) defines the implementation of the selection process with substitution, while the text is matched with the patterns in sequence.

The operation of the device for sorting information is as follows.

External control signals "ZAGR", "CHTPR", "WHAT", "START", "RSEL", "RESET", "RPOD" are fed to control unit 8, "GT", "SIN" from control unit 8. The input channel is an interface through which words arrive character by character. The output channel is an interface for issuing words.

In sequencing mode, the main idea of the work is as follows. Data is streamlined as it becomes available. At the input of the sorting device, the current word is entered and written into the BOP character by character, where the symbol is a component of the word having a fixed length. The beginning of the sorted array is the first character of the smallest word (number), the end is the last character of the largest, and the array is stored in blocks SBP1, SBP2. The indicated blocks are organized in the form of queues of the LIFO type (last to come - first to go), with the beginning of the ordered array being the first to come in SBP2 and the end to the first to come in SBP1. A search is made for the weight place of the current word in the array of already ordered data by character-by-character comparisons by the ES comparison element of the current word with the words in the array of ordered data. A weighted word is such a position of the current word in an ordered array when the word closest to it, which is one position earlier, is less than or equal to it, and the word that is one position later than the word is greater than or equal to it. Search for the weight of the current word is as follows. The first character of the current word is compared by the ES comparison element with the first character of the first word from SBP1 (Fig. 1). If the result of the comparison is equality, the second characters are compared, etc. until the result of the comparison is “MORE” or “LESS,” or one of the words does not end. Moreover, the compared characters are overwritten from SBP1 to SBP2. The result of the comparison of two words: if the words ended, at the same time - they are equal if the signal "MORE = 1" was issued by the comparison element ie the word symbol from BOP is larger than the word symbol from SBP1, or the word of block SBP1 has ended, but the word BOP is not - the current word located in the BOP is larger than the one examined from the ordered array. If the signal "LESS = 1" is issued by the comparison element, i.e. the word character from BOP is less than the character from SBP1, or the current word has ended, but the word being studied from SBP1 is not - the current word is larger than the word studied. Further, if the current word is equal to the word studied, it is written behind it in SBP2, if the current word is larger, it is compared with the next largest word studied, until the current word is equal to the next word from SBP1, SBP2, then it is written down after the next word studied, or not becomes smaller than the next one, then the current word from the BOP is written in front of it, or the end of the array is not reached, then the word from the BOP is written to the end. If the current word is less than the studied one, then it is compared with the next, closest smaller one of the studied, until it becomes equal to the next, or more than it, then the word from the BOP is written to the array behind the studied word, i.e. a position closer to the end of the array, or the beginning of the array will not be reached, when the beginning is reached, the word from the BOP is written to the array first.

The above-described entries in the BOP, search for a weight place, and write to the stacked memory blocks storing an ordered array occur character by character, are repeated n times, where n is the number of words to be ordered. After that, the ordered information is issued to the output channel in increasing or decreasing order. In selection mode, the work is as follows.

Data selection occurs from the input word stream based on the results of their comparison with the samples. At the input of the device, samples demarcated by symbols with codes 11 ... 1 are entered and written into SBP1, and first, samples are sent - the lower and upper boundaries, and then the samples for matching are equal, in which some positions of the symbols of the sample can be masked by writing characters with codes 00 ... 0 into them.

Next, the current word to be processed is entered and written into the BOP character-by-character at the input of the device. The adopted word is compared with the patterns. The comparison with the first sample is performed by more, while the first character of the current word is compared with the first character of the sample, etc., until the comparison result is larger or the sample ends first, and then the word is considered larger than the sample, or the comparison result less or the word in the BOP does not end, then the word is considered less than or equal to the sample and does not satisfy the selection condition (since the first sample should be the lower boundary). If the word is larger than the pattern, it is compared with the second pattern by less, while the first character of the current word is compared with the first character of the pattern, etc., until the result of the comparison becomes smaller or the word ends first, and then it is considered that the word is less sample, or the result of the comparison does not become larger or the sample does not end, then the word is considered greater or equal to the sample and unsatisfying condition.

If the word is smaller than the pattern, it is compared with the third, etc. samples until it becomes equal to the sample. The equalization on is as follows. Starting with the first characters, the word and the pattern are compared, until the result of their comparison is "equal" and they do not end simultaneously, otherwise the word and the pattern are considered not equal. In this case, the symbols are considered equal even if the symbol of the sample is equal to the special service code - the mask.

If the word is equal to the pattern, it is selected, i.e. is recorded in SBP2, if it is not equal to any sample, the word is considered unsatisfying.

Further, in case the word does not satisfy the condition, the next word is again loaded into the BOP and matching, etc.

At the end of the work, the selected words are issued in chronological or opposite order.

In the substitution mode, the work is as follows. At the input of the device, samples and substitutions are received and recorded in SBP1, and first the first symbolic sample is supplied, then the corresponding substitution, the second, etc., thus, the samples are placed in RAM SBP1 at even addresses, and substitutions at odd ones. Further, a fragment of the text to be processed is entered and written into the BOP symbolically at the input of the device. A comparison is made of the first received symbol of a fragment of text equal to ES with the first, second, etc. patterns until the symbol is equal to the pattern and then the corresponding substitution is written in SBP2. Or until the character is matched with all the patterns and is not equal to any, and then in SBP2 the current character of the text fragment being compared is written. The same is true for the other accepted characters of the text fragment. Next, the next fragment of the text is recorded in the BOP and it is also processed and so on until the end of the text. As the SBP2 overflows, in which the processed fragment of the text is stored, and also at the end of work, information is transferred from SBP2 to the output channel.

Block 2 RAM contains a midrange counter, register RG, random access memory RAM and a comparator KP (figure 2). To the inverse input of RAM, the choice of the crystal is fed by the constant "O" (not VK). Input information I1 goes to the RAM data input. The signal "OSCH = 1" is the zeroing of the counter. By the signal "RAM = 1" the input symbol is written into RAM at the address stored in the counter. By the signal "INSC = 1" the contents of the counter are increased by one. By the signal "ЗПРГ = 1", issued at the end of the word download, the contents of the counter, in this case equal to the number of characters of the word, are recorded in the register. If "ZPOZU = 0", the symbol located at the address stored in the counter is output to the output of RAM I2. The comparator KP, the inputs of which are the outputs of the register and counter, determines the sign of the end of the word "KS" with the equality of these codes.

Comparison element 3 contains a comparator KP (figure 3), which compares the symbols I2 and I3 received at its input and generates signals "MORE = 1" if I2 is greater than I3, "LESS = 1", if I2 is less than I3, and "EQUAL = 1 "if I2 is equal to I3.

The second stack memory block 5 contains a stack (Fig. 4) and serves to store part of an ordered array or selected words. By the signal "ZPS2 = 1", the I5 symbol is written to the top of the stack, by the signal "CTS2 = 1", the symbol to the I4 output is read from the top of the stack. In this case, the signals “C2PN = 1” are issued by the stack if the stack is full, and “C2PT = 1” if empty.

The first stacked memory unit 4 contains an NAV address counter, RAM random access memory, an RGA address register, a KP comparator, AND, OR, OR-NOT elements (Fig. 3). Information I7 is fed to the input of RAM data. According to the signal "ZPS1 = 1", which is input to the NAV and the write input to RAM, the I7 character is written to the RAM at the address stored in the NAV along the rising edge, the contents of which increase by one on the falling edge. According to the signal "ЧТС1 = 1", the content of the NAV decreases by one on the trailing edge, while the signal "ЗПС1 = 0" reads on the leading edge from RAM the symbol I3 addressed by the contents of the NAV. By the signal "CALCULATION = 1" the contents of the ACH are reset. By the signal "INSCA = 1" the content of the NAV increases by one. The output of the AM counter of the NAV corresponds to its lowest order. To the input of the least significant bit of the RAM address from the OR element, the signal AM & NORPOD∨POD & RPOD is sent. By the signal "ZPRGA = 1", issued at the end of recording the array of samples in the selection mode, the contents of the NAV is recorded in the RGA. To the inverse input of RAM, the choice of the crystal "not VK" is fed with the constant "0". The comparator KP compares the contents of the SCA and the DGA, the outputs of which are fed to its inputs and, if they are equal, gives the sign of the end of the array "KM = 1". Elements AND and OR DO NOT give out signs, respectively, the stack is full of C1PN and the stack is empty of C1PT.

Block 6 switching and identification contains a bus driver ShF with three states at the output, switches KM1, KM2, code generator FC, elements AND, OR-NOT (Fig.6). Serves for issuing a sorted array to the output channel OUT (figure 1) and switching information from various sources to the inputs SBP1, SBP2, as well as to determine the word boundary "GS" and the masked symbol "MS" in SBP1. At the signal "PB = 1" information from the input of the IF I3 is fed to its output I6. When "PB = 0", its output is in a high impedance state. Signals A1 and A2 are fed to the address inputs KM1, I5 is its output, to which input information I3 is transmitted via "A1 = 1", "A2 = 1", A2 is transmitted through "A1 = 1", "A2 = 0", or the service code of the boundary between the words generated by the FC code generator is transmitted, the specified connection is made by "A1 = 0", "A2 = 1". The signal A0 arrives at the address input KM2, I7 is its output, to which the input information is transmitted And4, if "A0 = 0", or And1, if "A0 = 1". The AND and OR elements do not emit signals, respectively, the boundaries between the words "HS" when the I3 symbol is equal to the code 11 ... 1 and the masked symbol when the I3 is equal to the code 00 ... 0.
