    • The processor comprises units for comparing the prescribed and current X and Y coordinates, whose control inputs are the control inputs of the processor and which are electrically connected with a random-access memory connected in series with a multi-channel switch. One input of the switch is the information input of the processor. A video adder has one input as the control input of the processor. Additionally included is a pattern line sequencing unit whose one input is coupled to the output of the multichannel switch, while three other inputs are respective control inputs of the processor, a Y coordinate search unit whose one input is coupled to the unit for comparing the prescribed and current Y coordinates, while the other input is one of the control inputs of the processor. An address multiplexer has one input as the address input of the processor, the next two inputs connected to the pattern line sequencing unit. Two other inputs are connected to the Y co-ordinate search unit and one more input is connected both to the pattern line sequencing unit and to the Y coordinate search unit while the output is connected to the random-access memory. A pattern analysing unit has one input as the control input of the processor, two other inputs and one output connected to the multichannel switch, another output is connected to one more input of the pattern line sequencing unit, another output is connected to the video adder, to the multichannel switch and to one more input of the address multiplexer. This is connected to one more output of the pattern analysing unit. The multichannel switch is coupled to one more input of the unit for comparing the prescribed and current X and Y coordinates and of the video adder, while the output of the unit is coupled to one more input of the video adder.
