Abstract

PURPOSE: To realize cursor display control only by providing a cursor display memory of N addresses by one bit and a simple gate circuit.
CONSTITUTION: Under the write control of CPU101, character codes are written in character display buffer memory 102 and cursor display assignment commands are also written in cursor display memory 103. In display control operation, character codes read out from memory 102 basing upon the address assignment from character display address counter 107 are made into single-character dot pattern data by character generator 104, so that CRT display unit 106 will display character information. On the other hand, information read out from memory 103 at the same time is sent to gate circuit 108 together with the contents of counter 107, thereby making a decision on whether cursor display is required or not.
