Zusammenfassung:The display processor comprises units for comparing the desired and current X and Y coordinates the control inputs being those of the processor and connected with a random-access memory. A multi-channel switch has one input as the information input of the processor, and a video adder has one input as the control input of the processor and the output as the output of the processor. The appts. additionally comprises an X and a Y coordinate search unit, one input of the two units being connected to the unit for comparing the desired and current X and Y coordinates, respectively, while the other input is a respective control input of the processor. An address multiplexer whose one input is the address input of the processor and another input connected to the Y coordinate search unit has two other inputs connected to the X coordinate search units, while the output is connected to the random-access memory. An image character analysing unit has one input as the control input of the processor, two other inputs and one output connected to the multichannel switch, the video adder, the multichannel switch and to one more input of the address multiplexer, to which one more output of the image character analysing unit is connected. The multichannel switch is connected to one more input of the unit for comparing the desired and current X coordinates, the unit for comparing the desired and current Y coordinates and to the video adder.
