The control unit (Fig. 2) has an exchange node 18, an input register 19, a first 20, a second 21, a third 22 groups of elements I, a pulse generator 23, a character generator 24, a third trigger 25, a fifth element And 26, counters 27 and 28 , the sixth 29 and the seventh 30 elements And, the element NOT 31, the fourth group of 32 elements And, the element NOT 33, the eighth element And 34, the fourth fourth trigger 35, counter 36, the group 37 elements OR, the second element OR 38, the element NOT 39 .

A coordinate word consists, for example, of the sign of the word type - 1 in the first category, always O in the third category, five bits of the Y coordinate (for example, 16-12p.) And six bits of the X coordinate (for example, II-6p. ), which provides the display on the screen of a cathode-ray tube (CRT) of sign information on 2048 familiarities with the format of 32 lines of 64 characters per line.

A sign word consists, for example, of a word type attribute — in the second category, a program selection flag — 1 in the third category, a sign of the last character in the displayed array — 1 in the fourth category, the sign code is recorded in 16-9 bits.

The information recording trays by the exchange end signal switch the control unit 2 to the display mode of the entered information. The processing of the information recorded in block 3 of the ferrite memory is performed using the signals of the decoder 5, which provide the display and editing of the information as follows.

Conventionally, all signals from the outputs of the decoder 5 are divided into groups, each of which performs a specific operation, for example, reading a word from block 3 of the ferrite memory, determining its type and activating the corresponding program (coordinate, sign, end of the display cycle), coordinate and sign processing of words. The signals in the groups are distributed in such a way as to ensure the temporal characteristics when processing the corresponding 1-1LOV. Consecutive, word by word, combining and processing the information recorded in block 3 of ferrite memory creates a corresponding image on the screen of a CRT. The control signals for switching the ferrite memory unit 3 into read or write modes come from the second to the fifth outputs of the decoder 5 to the corresponding:) Singing inputs of the ferrite memory unit 3, and the information is transmitted via the first connection input output with

the unit input of the trigger U, from the unit output of which the signals go through the fourth input of the control unit 2 to the third bit of the input register of the control unit 2. After that, the control unit 2 with the help of the signals of the decoder 5 processes the received word and, if it is coordinate, writes it to

55 its familiarity counter, connected via the first output of control unit 2 to the second input of comparison unit 6, and through the third output to block 30

com 1 mapping, if the word is a sign, it writes its information part (second byte) into its character generator and turns it on to generate and input to the display unit 1 the signals forming the configuration of the corresponding sign, as well as the backlight signals of this sign to enter them from the fourth output through the element And 17, too, in the display unit 1. Editing the information displayed on the screen of a CRT is made with a special sign by the marker formed through the character generator of the control unit 2 and installed in any familiarity screen by changing the state of the counter 7 from the second block 8 of switching elements. To correct any sign, a marker is placed on the familiarity of the display of this sign and a new sign code and editing signal are entered from the first output of the first block 4 of switching elements. As a result, the control unit 2 at the moment of displaying the old sign replaces it on the input register with a new one and records the new sign from the output of the input register via the first input-output link in the corresponding cell of the ferrite memory unit 3. As a result, a new character entered by the operator is displayed on the familiarity mark marked with a marker.

The device works as follows.

Before starting work, the first block of switching elements is installed in O of the trigger 25 and counter 27, and then the trigger 25 is turned on. Thereafter, through the element 26 of the generator 23 pulses, the counter input of the counter 27 receives pulses with a frequency of, for example, 1 kHz. Since the outputs of the counter 27 are connected to the corresponding inputs of the decoder 5, then on its outputs, starting from the first one, one after another, control signals begin to appear. The first signals from the decoder 5 arrive at the input of the ferrite memory unit 3 and read the information from the corresponding cell and overwrite it to the register 19 through the first input-output connection, then the next signal from the decoder 5, which enters unit 2

27. Start code for the corresponding program. Usually, an array of displayed words begins with a coordinate word, i.e. from installing a CRT beam on

10 certain familiarity on the screen of a CRT (any of 2048). In this case, the signals of the coordinate program from the output of the decoder 5 arrive at interrogating the second group of elements 21 and write 15 the corresponding code to the input of the counter 28, from the output of which this information enters the display unit 1, and to the second input of the comparison unit 6. After counting the time that the CRT beam outputs to the corresponding point on the screen, the signal from the decoder 5 receives the signal of the end of the coordinate program that passes through the OR 38 element and the HE 31 element to be set to O in the counter 27. As a result, from the first outputs of the decoder 5 pulses arrive at the input of block 3 of the ferrite memory for reading the next word. If the word read from block 3 of ferrite memory and written to input register 19 contains sign information, the signal from the output of the first group of elements AND 20 is passed through the group of elements OR 37 to set the code for the beginning of the sign program to counter 27. The first signal of the sign program polls the third group of 22 elements And, writes the sign code on the input register of the character generator 24 and turns it on. Signals for forming a mark on the screen of a CRT come from the output of the character generator 24 to the input of the display unit 1, and the illumination signals are received

5 are fed to the first input of the AND element 17, from the output of which, under the condition of an enabling signal at the second input, is also passed to the input of the display unit 1. After counting the time for forming the sign, the following signals of the sign program come from the input of the decoder 5 to the counting input of the counter 28 to set the code of the next familiarity, set to 0 the account 55 Ch1psa 27 through the element AND 29, the elements OR 38 and HE 31 and poll the corresponding element AND from the first group of 20 elements And for the analysis of the sign of con5

array array (the last word of the array). If the processed sign word is not the last, then the next word is read from block 3 of the ferrite memory, if the last one, then the signal from the output of the corresponding element AND of the first group of 20 elements AND goes to the installation of the counter 28 and the trigger 25, which blocks the passage of the frequency through the element AND 26 to the input of the counter 27. Because of this, the device continues to operate only the counter 36, which provides a constant frequency of information regeneration. When the counter 36 counts the frame time, for example, 20 ms, from the output of the AND 30 element a signal is received to turn on the trigger 25 and through the decoder 5 to install the ferrite memory unit 3 into the zero-address register. As a result, the frequency begins to arrive at the input of the counter 27, the first word is read from the memory block 3, its processing, etc., i.e. inclusion of the next cycle of information.

When editing information, the operator after installing the marker on the familiar editable character enters from the first block 4 switching elements the code of the new sign to the information input of the fourth group of 32 elements AND, and the control signal to the single input of trigger 35. Now at the moment of displaying the corrected sign on the inputs of the element And 34 there is a coincidence of the signals from the single output of the trigger 35, the output of the comparison unit 6 and the signal of the sign program from the output of the decoder 5. The signal from the output of the element 34 passes through the third element 33 is not for polling the fourth group of 32 elements And and writing to the input register 19 the code of the new sign instead of the code of the old sign. The signal from the zero output of the trigger 35 blocks the passage of the last signal of the sign program through the AND 29 element to set the counter 27 to zero, which continues to count and automatically goes to the word recording program from the input register 19 to the cell of the memory 3, the address code of which remains on the address case, i.e. code of the address of the cell in which the code of the old mark was written. After the end of the recording, the last signal of the recording program sets the following state on the address register of the block 3 of ferrite memory and passes through the elements OR 38 and HE 31 to the installation in O of the counter 27 to activate the reading program of the next word, as well as to the installation in O

trigger 35.

To programmatically select any of the displayed characters, a marker is placed on his familiarity and from the second output of the first block 4

switching elements, a control signal is inserted, which through the element OR 1 enters the control unit 2 to activate the rewriting of sign words in the ferrite block 3

the memory, and through the element NOT 13 - to the third input of the element I 12. Now, at the moment of displaying the selected character from the output of the comparison unit 6, the first input of the element 12 receives the control signal, and the second input receives the signal from the sign program from the eighth output decoder 5. The signal from the output of the And 12 element sets in one state the trigger 10, which, in turn, ensures that the corresponding bit of the input register of the control unit 2, containing the sign of the program selection, is set in the trigger. After processing for display, this word with an already recorded software sign is rewritten via the first connection of the control-2 control input-output back to the ferrite memory block 3 in its own way.

address. The installation in O of the trigger 10 is made, for example, by the last signal of each sign program.

Thus, in block 3 of ferrite memory, a program mark is recorded in a certain cell with a mark code. Every time when reading from the block 3 ferrite memory of words containing a program feature, the signal from the corresponding bit of the numeric register of the block 3 memory goes only to the second input I 9 and through it to turn on the trigger 10, the unit arm of which is connected to the third input of the third element, to the first input of which a pulse signal is received, to start processing the sign program from the decoder 5, and to the other input - the meander frequency, to

Example, 12 Hz (J-i-J-L). When the enable signal is received from the unit arm of the trigger 10 when processing a sign word, the signal from the generator 14 passes through the element 15 to trigger the trigger 16, which in this case blocks the signal of the processed sign to the display unit from the zero output, and the mark is not displayed on the CRT screen. The setting in the flip-flop 16 is, for example, the last signal of each sign program from the ninth output of the decoder 5. With the inhibit signal from generator 14, the AND 15 element is blocked and the backlight of the characters is not interrupted. Thus, the interruption of the illumination of characters containing a software feature is performed with the frequency of the generator 14, for example 12 Hz, and the operator can observe on the CRT screen the blinking of all characters at a certain level of which. contains programmatic feature, i.e. visually monitor the information to be selected to make a decision about entering it into a digital computer. After entering the information in the digital computer or in case of an error, the program signs contained in the sign words of the cells of the ferrite memory unit 3 can be erased by inputting the inhibit signal from the third output of the switching elements 4. As a control signal, this signal passes through the first element OR 11 to the fifth input of control unit 2 to enable the rewriting mode of each word read from block 3 of ferrite memory from the input register of control unit 2 through the information output, without changing the addresses read of words. In addition, the signal from the third output of block 4 of switching elements arrives at the first input of element AND 9 and blocks the passage of signals through it, including with the help of flip-flop 10, the corresponding bit allocated for the program feature of the input register of control block 2. After reading each word from memory block 3 and processing it in control block 2

the words are written back to the old address without program signs. During one cycle

Neither the array of words from the memory block 3 erases all the program features in the words and stops blinking on the CRT screen of the previously selected characters.

An introduction to the proposed device of new blocks and connections provides the possibility of programmatically highlighting (marking) displayed 1 "xx" on the screen of signs with reverse control, such as blinking, which allows a significant increase in the speed of the device.
