The drawing shows the structure of the device ..

The device contains the first element NOT 1, the third counter 2, the fourth and fifth counters 3 and 4, the first trigger 5, the first register b, the block 7 of the permanent memory, the third decoder; 8, the first element AND 9, the first switch 10, the second switch 11, the W 12 element, the first counter {increment counter along the coordinate X) 13, the second counter (increment counter along the coordinate U) .14, quarter-decryptor 15, sixth counter 16, its third switch 17, second trigger-ep 18, synchronizer 19, first and second adders 20 and 21, first and second decoders 22 and 23, matrix indig, cator panel 24, second element, And 25, single-shot 26 , pulse generator 27 ®, second register 28, third register 29, second element NOT 30, fourth register 31, first in T device (reset input) 32, a second input (information) 33, a third. 65

input (Start of character painting) 34, fourth input (Xd) 35, fifth input (PP) 36, sixth input (Record) 37, single input (Erase) 38, eighth input (Complete erase) 39, device output 40.

The device is designed to display characters of various formats, for example 16x16; 7x5, 6x4, when using a 8-bit constant-memory block and works in three modes: recording, erasing and completely erasing the reproduced information.

When the calculator accesses the device to display the information required by the program calculator, a symbol code is sent to the input of the counter 2, a pulse Reset from input 32, embedding the coordinate increment counters 13 and 14, the operating mode selection signal to the register 31; the initial setup codes XQ, SP from inputs 35 and 36, and impulse Beginning of the painting from entry 34, at the front mount of which, the character code in counter 2 is recorded, the nautical installation codes in the register | l and 29, and the signal p in the operation mode in register 3.1 as well as the resetting of the counters 3, 4 and 16 of the trigger 18 and the one-shot 26 is performed. At the output of the counter 2, a code of the displayed symbol is determined which determines the selection of the corresponding matrix of the fixed memory 7, i.e. at the output of block 7, a code appears written in the first column of this test. On the falling edge of the pulse. The beginning of the painting is recorded by the first column of the matrix of block 7 into register 6 and the trigger 5 is set to one, on the inverse output of which a signal appears that prohibits further transfer of the HH formation to the device from the computer for the duration of the ryusis. character.

Thus, the device is prepared for character painting - at the output of register 6 there is information about the character format and additional codes of necessary image movements along the coordinate axes, at the direct output of flip-flop 18 - logical O, which prohibits the launch of the one-shot 26 and thus prevents painting of dots the first column in which information about the character format is recorded on the screen is indicator-. panel 24. The synchronizer 19 emits pulses with a frequency of 4 MHz, which, after passing through the element 12, arrive at the input of the increment counter along the axis U 14 and the sixth counter (points) 16.

After the arrival of the eighth pulse at the first output of the counter 16, a logic switch 1 appears, which indicates that one column of the matrix is counted, and sets trigger one 18 into one state, which opens element 25, 1 is the most resolved to start the radial 26 later. In addition, on the level difference at the inverse output of the trigger 18, an initial increment is recorded from the first register 6 to the counter 13.

Logical 1 from the output of counter 16 is also fed to the counting input of counter 3, according to the output codes of which the next column of matrix is selected (s from block 7, the codes of this capital from the output of block 7 in parallel code are fed to the first input of switch 17, to the second input which receives the codes for the 16-point counter. These same codes are fed to the input of the decoder 15, which generates a write signal to the LUo initial increment counter 14 from the first register when the first point of each column of the matrix is generated. ovoe scanning columns of the matrix character.

Logical 1 at the output of the switch 17, indicating the need to illuminate a point, passing through an element 25, triggers a one-shot 26 a pulse at the output of which, inverted by an element NOT 30, closes the element 12, preventing those further operation of the device for 20 µs.

Over these 20 ISSs, the pulse generator 27 forms, in accordance with the work mode recorded in register 31, the voltage levels necessary for recording or erasing points in the coordinates set at the outputs of the adders 20 and 21,

Switch 10 controls the counting input of the counter 13 increments (along the X axis), while if the character format is medium (5x7), the switch issues one pulse every eight points, if the format is large (16x16), then every sixteen points.

Element AND 9 controls the counting input of counter 2. If the character format is large (16x16), this means that it consists of four medium format matrices (8x8), in this case, the output of the AND 9 element generates one pulse for every eight

5 columns counted by counter 3, and the code at the output of counter 2, being a single increment of the character code, selects the next matrix from block 7..

0 Switch 11 .. controls the operation of trigger 5, which gives a signal that the character is finished painting. Moreover, if the character format is large (16x16), then the switch issues a logical 1 signal after thirty

two columns (counting is done by counter 3 and counter 4) if the format is small (4x6) - through six columns (four columns are the width of a symbol and 0 are two columns is the skip value for text display), if the format is medium (5x7) - through eight columns (five columns are the width of a character, three columns are a space).

5 Counter 14 counts

points of the microrastic matrix, taking into account the increment Up, which is rewritten into it in the head of each column.

0 Counter 13 counts the columns, taking into account the increments of X, written into it at the beginning of each matrix with a size of 8 columns. Counters 13 and 14 together with

5, adders 20 and 21 are cumulative elements.

Thus, if after, ending the painting of one character, a set of new codes from the calculator is submitted

0 sigteols, not giving out the Reset signals, and the codes of the initial coordinates XQ and EO, then as the pulses start working, „the painting will start a textual display of information with an account

From iropuskov between characters of different formats. In comparison with the known, the proposed device allows reproducing symbols of different formats while maintaining speed, J. reproduce texts, and

 from characters of different formats with spaces proportional to the format by mesvdu characters.
