Abstract

PURPOSE: To decrease the memory capacity of the character generator by driving the character generator through conversion of the character code into the character number corresponding to the characters of the necessary number.
CONSTITUTION: The character data based on the 16-bit JIS code is memorized in display memory 1 and in the amount equivalent to one picture frame. The character data of memory 1 are read out in sequence based on the line and character counter information given from synchronous signal generator circuit 8, and the 14 bits are applied to code conversion memory 2 in the form of the address. Memory 2 delivers the character number corresponding to the character code of the necessary number and also delivers "0" to other character codes. Character generator 10 delivers the character pattern information based on the character number. Thus the memory capacity of generator 10 will do with the character number required for the display.
