The purpose of the invention is to increase the speed of the device.

The device contains a control unit 1, 6.1 POC 2 interface, the first switch 3, the second switch 4, the video monitor unit 5, the first memory block 6, the calculator 7 increments of coordinates, the first distributor 8, the Fremeia code generator 9, the address code generator 10, priority block 11, second memory block 12, third b-. 13 memory, the fourth memory block 14, the first counter 15, the second decoder 16,; the first re (-master 17, the third decoder 18, the fourth decoder 19, the first driver of the 20 rectangular pulses, the second register 21, the fifth decoder 22, the second counter 23, the second shaper 24 rectangular pulses, the elements AND-NOT 25, the first adder 26, the fifth memory block 27, the multiplier 28, the second adder 29, the sixth decoder 30 and the elements OR 31.

The device works as follows. Through the input bus to the interface unit 2 from the external device, information is recorded in the memory units 12-14 and the first register 17 of the control unit 1. In the thief block

12, the description of the curves (configurations) in the form of lists of directions is loaded. At the same time, the second block 12 of the memory receives data on the directions and the number of the directions in the list, which are the address of the memory cell 12. In the third block

13, the signs of transformations of the displayed configurations are recorded,

namely, the zoom, rotation angle, offset, and the initial coordinates of the configurations. In the fourth block

14pami records the configuration color, flicker and scale data. The addresses of the third memory block are the curve number codes. In the further context

in terminology, only curves will be mentioned.

The device has four modes of operation; “Download,“ Write, “Transform, and“ Read. In the "Loading information from input ipsy" mode, it goes to the interface 2, from which the 12-14 memory of the device is loaded.

In the mode “Loading the fourth memory block of the address in the form of curve number codes comes from the first switch 3. Switch 3, under the influence of a control signal coming through the control input from the interface block 2, connects the information inputs of the fourth memory block to the second output of the third block 13 of the memory at boot or to the output of block 11 priority when displayed.

In the first register 17, the control unit status register receives the curve number addresses, data, commands. The loading of the second memory block 12 is carried out sequentially. After each transmission and recording of the next direction from the computer, the state of the second counter 23 of the conjugation unit 2 increases by one. Thus, a full description of the curve is stored in the second memory unit 12, and at the end of the description of the curve, the end marker is shifted to recognize the end of the curve.

Recognition is the first decoder 8 - decipher end of the array. The signal from the array end discriminator is reset to zero by the counterblocker 23. The write enable signals in blocks 12-14 are received respectively at the control inputs. After loading of blocks 12-14 of memory, information is recorded in the first block of memory. At the same time, from the third memory block 13, the initial coordinates xn, UN, are received from the third information input of the calculator 7 coordinate increments, and the first information input from the second memory block 12 - direction data.

From the calculated increments of the coordinates x- | -1, X-1, y- | -1, Y-1, arriving at the second output of block 7 on shaper 9 of the Freeman code, the latter generates codes of one of eight directions, which are written in The first memory block 6 is an image memory block. The write pulse is fed to the first control input from control unit 1. The sign of the curve to the image storage unit is supplied via the first information input from control unit 1, and the addresses from block 7 via the second switch 4 (addresses) to the second information input of the image storage unit. After recording the information in the image storage unit from control unit 1 on the fourth output, a signal is received at the control input of the second switch 4 (addresses), which connects the output address groups of the switch 4 to the video monitor unit 5. At the same time, the output of the first switch 3 (addresses) is connected to the input connected with the output of the block 11 priority.

From the output of block 6 of image memories, the codes of the address of the curve number through priority block 11 and the first switch 3 (addresses) arrive at the second information input of the fourth block 14 of memory. At the output of the fourth memory block, video signals are formed, which are fed to the display in the video control unit 5.

0 The clock frequency for the operation of the control unit 1 comes from the video monitor unit on the second output.

In the “Transformation” mode, the commands “Rotate,” Scale or “Offset” are received from the computer, while the information of the second memory block is not overloaded. When a command is received from a computer, for example, “Turning to the second information input of the calculator 7 coordinate increments from the third memory block 13, data about the magnitude of the rotation angle and

 data directions. In the Transform mode (rotation, scale, offset), the operation occurs in two stages. At the first stage, the information is erased in the first memory block - the image memory block, at the second - the recording. The calculator 7 increments of the coordinates determines the increment of the coordinates x- | - 1, X-1, y-f- 1, y-1, on the basis of which shaper 9 of the Freeman code is determined., The direction code is used for writing to the memory block.

images. After the arrival of the next unit direction vector, the cycle is repeated, and the Freeman code generator generates the following code. Thus, a graph rotated by an angle determined by the data from the third memory block 13 is recorded in the image storage unit. The transformation mode includes two operations — erasing the old image and recording the new transformed one.

The image memory block is divided into parts corresponding to each curve, and the data is represented by the word as:

When a curve is transformed, operations are conducted only with a portion of the image storage unit corresponding to the curve. In the image regeneration mode, all parts of the image storage unit are read at the same time and therefore it is sufficient to read only the indications. In the Transform mode, operations are also performed with a portion of the image storage unit corresponding to the number of the curve to be converted. When erasing the graph in the image storage unit, information on the number of the curve is passed to the control unit 1. At the third output of the control unit, a signal of a curve appears, which is written to the image storage unit. When erasing, the signal of the curve feature is zero. At the calculator 7 increments of coordinates simultaneously arrive coordinates X, MIND erasable curve. The coordinates x ". The calculator 7 generates addresses for the image memory block and at these addresses information is erased and the curve vector codes are simultaneously written to the address code generator 10. According to the recorded code, the absolute address shaper generates coordinate increments x ± 1, y + 1. which are fed to the calculator 7. The calculator 7 again generates absolute addresses for erasing the next vector in the image storage unit. Thus, erasing the entire curve to be transformed in steps.

The control unit 1 serves to recognize commands from the interface and generate recording pulses and other pulses controlling the operation of the device. After data and commands are written to the first register 17 of the control unit, the second de- scraper 16 outputs, by zero or one, a transformation or load signal to the inputs of the third demarcator 18, to the other input of which signals are sent in the form of curve number codes to the second information input of the control unit. Curve feature information is provided to the image storage unit. The clock frequency from the video monitor unit 5 enters the control unit 1 via the second synchronous input and starts the first counter 15 - the clock counter. The fourth decipheror 19 forms the main pulses controlling the operation of the device.

The operation of the coordinate increment calculator occurs under the control of the control unit 1. From the second memory block 12, information about the directions (b,) in the list is received at the first information input to the first adder 26. Additionally, the first adder receives information from the third memory block 13 about the sign of the transformable curve P (rotation, shift, change Scale). At the output of the first adder, a summary code appears, equal to b / -) (P), which is fed to the fifth memory block 27 — a sinus-sinus-permanent memory device (ROM). At its outputs, codes of the sine and cosine values of the direction (L / - | -P) are formed, which are fed to the input of the multiplier 28 coordinates X and y. In addition to the input of the multiplier, the scale codes in x and y coordinates (M, My) are received from the third memory block 13. At the output of the multiplier are

, product codes, i.e. Mxcos (b, - | -P) for one channel and MySin (b, + n) for another channel. From the outputs of the multipliers of each channel, signals are fed to a second adder 29, the output of which forms the address XK and HC for the image storage unit.

At the same time, the address of the direction number in the list of directions, direction data, addresses for the third memory block 13, curve number, conversion signs, data,

 commands, curve indications (1 light, flicker, scale) for the fourth memory block 14 All information is used during device operation. The direction addresses for the second memory block 12 are generated by a second counter 23 of the interface block. Counting pulses to the counter come from the control unit when writing information to the image storage unit or from the interface unit when loading the second memory unit 12. Reset counter 23 to zero

, occurs on the third input by a pulse from the decoder 8 - the decoder of the end of the array. Gating recording pulses occurs output pulse coming from the computer at the input of the device.

As can be seen from the operation of the device,

0 information about the generated graphs (configurations) in the form of a description is stored in the second memory block, the download of which from the computer occurs once before working with the device. In the known device for displaying information, the construction of a graphic image from straight line segments (vectors), and the representation of the vector is carried out by specifying the components of the vector and the initial coordinates. Moreover, the initial coordinates and components of the vector

Q is transmitted each time a next vector is formed. In the proposed device, it is not necessary to transmit the initial coordinates of each vector to display information, and the initial coordinate of the entire graph (configuration) is transmitted from the computer.
