Screen display circuit.

摘要

A screen display circuit having a display memory (15) and a code discriminating and controlling circuit (18). The display memory (15) stores a character storage address and a display control code as different data. The code discriminating/controlling circuit (18) discriminates if the output data read from the display memory is the character storage address or the display control code. In accordance with whether the output data from the display memory (18) is the character storage address or the display control code, the transfer destination of the output data is changed. It is not necessary to have a display control code for each display character, thereby reducing the size of the display memory. <IMAGE>
