发明名称 DISPLAY CONTROL DEVICE
摘要 A display control device according to the present invention includes a common memory having two funtions, one as a refresh memory for outputting a character code and the other as a character generator for generating a character font, an output character code from which is stored in a line buffer. In this case, a display address generator circuit generates a character address for generating the character code and a raster address for designating the character font, which are in turn switched by an address selector and outputted to said common memory which then outputs a video signal to a video control circuit based upon said character font. Additionally, there is provided a line buffer control circuit for outputting a read/write access control signal to said line buffer based upon the raster address.
