Description

The invention relates to automation and computing and can be used as an external device for outputting graphic and digital-information information on the display device screen. A device for displaying information that contains a buffer memory block, an indicator block connected to a sequentially connected video shaper, a symbol generator, and a memory block of a character string whose control inputs are connected to the code of a synchronization block connected via an address shaper and writing signals is known. with the control input of the buffer memory block fl 1. The closest technical solution to the present invention is a device for displaying information containing a decipher Op input signals whose outputs are connected to an image code generator, an address word generator, a buffer memory block and a constant code and presentation command code generator, a synchronization unit, the first output of which is connected to a constant code generator and a coma: presentation code connected to the buffer memory block ti connected to the output of the image code generator, an address shaper and write-read signals, one input of which is connected to the address word generator, the other to the second output of the synchronization unit, and the output - with a block of buffer memory, serially connected first block of strings of characters, character generator, video driver, other inputs of which are connected to the third, fourth and fifth outputs of the block, synchronization, respectively, indicator block, word generator block connected to the sixth output of the synchronization block, output, desh1 1} of the command farmer 2. However, with this construction of this device, the number of characters generated in the string is determined not so much by the bandwidth of the indicator path, for example an ionic monitor, and the speed of reading and converting word code circuits, which leads to the complication of symbolic transformation of layer codes by using high-speed memory blocks and word generators. In addition, if it is necessary to distribute the information stored in the buffer memory block into several indicators, it is necessary to increase the entire path from the buffer memory block to the indicator. The purpose of the invention is to simplify character-by-character conversion of layer codes and increase the amount of information displayed by dividing the word codes of a string over time, character-by-character conversion of word codes, and element-wise character conversion. The goal is achieved by the fact that the device for displaying information contains a memory block of the word string S whose first input is connected to the code of the buffer memory block, the second input to the output of the synchronization unit, and the code to the command decoder and layer generator, respectively, and the second a block of memory of character strings, one input of which is connected to a word generator block, another input - from eight 4 outputs of a synchronization block, and an output - to a second input of the first memory block of a string - SYMBOLS ,, The drawing shows a block diagram devices. The device contains I input signals, the outputs of which are connected to the image code generator 2, the address word generator 3, the buffer memory unit 4 and the constant code and presentation command generator 5, the synchronization unit 6, the first output of which is connected to the constant code generator 5 presentation commands connected to the buffer storage unit 4, connected 1 to the output of the generator 2 image codes, shaper 7 addresses and:, write-read signals, one input of which is connected to the generator 3 address words, the other from the second eye OUTPUT of the synchronization unit 6, and the output with the block 4 of the buffer memory connected to the first input of the block 8 of the memory of the word string, the first output of which is connected to the decoder of 9 commands connected to the block Yu of the word generator, and the second output with the block 10 word generator connected to the first input of the second block of 11 strings of character strings, the output of which is connected to serially connected first blocks of 12 strings of strings of characters, the generator of 13 characters, shaper 14 video signals, the other inputs of which are connected to the third, fourth and n th outputs sync block, respectively, a sixth output is connected to block word generator, and the seventh and eighth outputs - to the second input storage unit and a word line block generator word respectively, device display unit 15 operates as follows. The words of the representation in ST5 are read from the buffer memory block 4. The words st5 are inserted into the memory block 8 in the memory block 8. The number of read lines of words is determined by the number of indicators on which the information stored in block 4 of the buffer memory is distributed for simultaneous observation. The memory block 8 is filled in alternately with each line of words. For example, if two television monitors are used as indicators and the time for eight television lines (seven per character with the number of decomposition points 5x7 and one line and interval) is set aside for the formation of the image, then alternately filling the block is performed during the interval television timeline 8 word line memories for the first monitor, and then words for the second monitor. Within two to eight television lines of word code from block 8 of memory, the lines of words of the first and second monitors alternately arrive at block 10 of the word generator, where the corresponding word generator (digit-letter, graphic, binary-decimal, etc.) is turned on. ) by a command from the decoder of 9 presentation commands, launched with command bits as part of a word code read from block 8 of the line memory.

In word generator unit 10, word-by-character word conversion is performed using control signals received from synchronization unit 6. The codes of the components of the word characters for the second to eighth lines alternately fill the second block} 1 of the first and second character string memory

tori.

During the next interval TV line, the next line of the image of the first and second monitor is read from the buffer memory 4, and the character codes from the second memory 11 of the first and second monitor strings are simultaneously overwritten.

in the first memory block 12, the strings are the characters of the first and second monitors.

Over the next two to eight television lines, word-by-word translation of the next image line of the first 25 and second monitors is performed and the codes and symbols are filled in the second memory block 11 of the character string of the first and second monitors. Simultaneously, from the first block of 12 memories, the character strings of the first 30 and second monitors character codes alternately arrive at the generator 13 characters, where for each tele

The display line is converted (the formation of each character on the ground, the mental positional codes. The positional elementwise signal conversion codes are fed to the video signal generator 14. The video signal generator 14 uses a decomposition pulse from the synchronization unit 6 to temporarily unwind the positional codes converting characters for each line of the first and second monitors, generating the light signals and image synchronization. Light signals (video signal) and blue image is fed into indicator block 1 The proposed device as a result of simplifying the character conversion of word codes by dividing word codes from the buffer memory block in time, character character conversion of words codes, and element-by-element character conversion allows the use of slower, but with more integration elements such as integrated circuits, making it more compact.

In addition, an increase in the amount of displayed information using the same generators of symbolic words due to the separation in time of reading the codes of words from the buffer memory block, character-by-word conversion of word codes and element-wise conversion of symbols allows expanding the capabilities of the proposed device in the operative presentation of monitored information.
