Description

(54) 1 DEVICE FOR DISPLAYING INFORMATION WITH THE CONTROL UNIT, a data device with the output of the first AND element, two BXoflia of which are connected to the generator output and the trigger output, one of the inputs of which is connected to the control unit of the penalty, and the second to the W input The second element, And, one of the inputs of which is connected to the permanent memory unit, and the second to the last output of the corresponding 11th counter, controls the rake vkddag second and third perHC-ppv connected to the control unit, infedrmed1НН11e to the buffer unit nawsmi, and Bbix & flbi via In the seam, the decoder is connected through a key block and directly to the output of the matrix screen, the outputs of the fixed memory block via the OR element and the third element AND are connected to the second key block inputs. The block is in the drawing representation. . Compound control unit. neither 1, blockbuffer memory 2, registrar1 3, 4, and 5, ring counters 6 and 7, deshchi Lch5atory 8, 9, and 10, key block 11, matrix screen 12, fixed memory block 13, generator 14, electric & The cops are AND 15, 16 and 17, the element OR 18 and the trigger 19. The device acts as a follower. in a way. : - :: --- :. V - A-; - -. Under the influence of the control signal, the output is generated in control unit 1, all registers 3, 4, 5 are reset to 1nul, and in the first days KprtbiieBbix counters b and 7 jBaetcst records; unit; . .:.:.: 7.; ::. ;;; :: .. Under the influence of the control cwr, .b, the character code is written from the buffer memory 2 to the first register 3 of the character code, and to the second 4 Third third register is the coordinate of the start of the program, decoding the selection of a specific bus in the permanent memory unit, and the selectors of the first 11 correspond to the pinpoints of the driver and the driver, and the block of the corresponding information is given by the driver and the headset and the unit is correspondingly matched to the main unit. is the starting point of the character to be displayed. The element selected in this way does not excite, since the signal does not receive a signal to the second blocks of the block:; Under the influence of a control signal generated from the uzfa block of laziness. 1 flip-flop 19 flies, and pulses are generated by a generator

646358 14J pass through the first element AND 15 These pulses go to one of the inputs of the third element AND 17, the second input of which through the element OR 18 receives signals from the output of the fixed memory block, in which the information about the pulses of the backlight is covered; the symbols extracted from the el; decomposition of a small-format television raster. The pulses from the element I 17 are fed to the second inputs of the key block 11, which results in the excitation of the matrix screen elements chosen according to the law of a low-format television raster. The pulses from the output of the first element And 15 arrive at the counting side of register 4. The end of the output to syog 6 and 4p: the contents of register 4 are incremented by one: The same flow goes to (after the ring counter b and the back front translates it into the next steady state. This achieves the "unwrapping of the block of the permanent memory 13 to the lines of the structure .... v:;, i:; r....:.,; U ..-.. after sampling in the block of the permanent memory 13 of each elevenement is fed to the impedance on the throne 5 and the contents of the & & nd one is increased by one. EiisshJ is achieved by switching the block "; And nocTOS memory 13 in synchronous columns with a sample of decomposition elements in the world screen, since After sampling the tusps of an element in the memory line 13, the ring counter 7 is transferred to the second, third IT The stable bus 6 in the Permanent Memory Unit 13 is received at the inputs of the warmers of the terminal and 17 4epie3. counter 7 and the last element in the memory block 13.. Therefore, during the sampling of the last element in the memory of the permanent memory 13, the syllable AND 16 passes syneal, which, with one, sets the trigger 19 to the initial state, and another informs the control unit 1 and informs it about the end of the process. . Formula of a device. A device for displaying information containing a control unit, a buffer memory unit and a matrix screen.

the outputs of which are connected to the block of buffer memory, distinguish neo 3 in that, in order to expand the field of application of the device by increasing the decomposition elements in the matrix screen and adding securely, a fixed memory block, a key block, three decoders, two ring counters, trigt, genogrator, elements AND and OR, and three registers, w 1 the first register through a decoder are connected to the terminals of the permanent memory unit, the others of which are connected to the outputs of the two nine ninth counters, the control inputs of which are connected with the control unit, and the informational one with the output of the first sheath And, two inputs of which are connected to the output of the generator and the output of the trigger, one of the inputs is connected to the unit: control, and the second To the output of the second element And, one of

the inputs of which are connected to the block of permanent memory, and the second - to the output of the corresponding ring counter after it, the control inputs of the second

of the third and third registers connected to the control unit r informational - to the buffer memory block, and the outputs turn the corresponding switches, via the key block and directly to the outputs of the matrix screen, the outputs of the Constant memory block through the OR element and the third element AND the second inputs of the key block.
