Description

The invention relates to computational techniques, in particular, to devices for displaying information. According to the main author. St. No. 824285, a device for outputting graphic information is known, comprising a pulse generator, the output of which is connected to the input of a point counter, the first output of which is connected to the input of a row counter, and the second output of a point counter and the first output of a row counter are connected to the inputs of the first decoder unit, output1 of which through the first, second, third and fourth trigger l are connected respectively to one of the inputs of the analog adder, the output of which is connected to the television display indicator, and the other input of the analog adder is connected n to the output of the first element, the first input of which is connected to the output of the shift register, the recording input of which is connected with the corresponding output of the first decoder unit, and the synchronization input to the output of the pulse generator, in addition, it contains an address counter, the second decoder unit, the second elements You are the Fifth trigger, the second output of the row counter and the third output of the point counter are connected to the corresponding counter inputs, the addresses, the second output of the point counter is connected to the input of the second decoder unit, the output of which is are connected to first inputs of the second AND gate, second u third inputs being connected respectively to the outputs of the second and fourth flip-flops, and the first block decoders coupled through fifth flip-flop with a second house WMOs first AND l. The disadvantage of this device lies in its low speed when viewing the contents of the EV memory. The purpose of the invention is to increase the speed of the device. The goal is achieved by the fact that the register is sequentially connected to the device, the inputs of which are the inputs of the device, and the second adder, the other inputs of which are connected to the address counter, and the output is the output of the device. ma device. The device contains a generator of 1 pulses, a counter of 2 points, an account. tick 3 lines, counter 4. address, second {5 elements, 5, first decoder block b, second decoder block 7, first 8, second 9, third 10, fourth 11, fifth 12, shift register 13, first element And 14, analog adder 15, television indicator 16, start address register 17, adder 18. The device works in a following way. . The pulse generator 1 generates high-frequency pulses corresponding to the required screen rasterization horizontally, which is fed to the input of the 2-point counter and to the synchronization input of the dvd register 13, shifting the information contained in it which is stored from the computer memory. The capacity of the shift register 13 is equal to the memory word width. The conversion factor of the counter 2 points corresponds to the TV standard of the horizontal scan duration. The signal from the high-order output of the 2-point counter enters the 3-row counter input, which recalculates image lines, in a frame and has a recalculation period corresponding to the frame sweep duration. The signals from the outputs of the counter 2 points and the counter 3 lines arrive at the inputs of the first 6 and second 7 blocks of decoders. The first decoder block B generates control signals to write the information word to the shift register 13, toggle the first trigger 12, which allows the video signal from the shift register 13 to pass through the first element 14 and during the frame beam and horizontal sweeps and the horizontal pulse formation signals generated by the first trigger 8, a pulse of the lower-case protective strip formed by the second trigger 9, a personnel pulse generated by the third trigger 10, the pulse of the personnel protective strip formed by Rotary trigger 11. The components of the television sync mixture thus obtained, together with the video signal received from the output of the first element I 14, are converted by the analog adder 15 into a standard television video axle, which is fed to the video input of the television indicator 16. The signals from the output of the second decoder 7 go to the second element 5, on which, together with signals from the outputs of the second 9 and fourth 11 flip-flops, the next-word request signals from the computer are formed, and the next-word query word from time displacements in shifted previous word in the shift register. The starting address of the output aa array screen is entered from ES4 into the register 17 of the starting address. Counter 4 of the address forms the change of the address of the read words synchronously with the generation of signaling queries of the query 3 1078450
