Abstract: PURPOSE: To provide a method and device by which the displaying efficiency of characters can be improved, when the characters are displayed on the display of a data processing system. CONSTITUTION: A character-displaying method includes a plurality of processes for displaying characters on the display 22 of a data processing system 10. Each process requires various quantities of processor resources for displaying the characters on the display. Such a process that the characters can be displayed on the display more efficiently than the other processes is selected out of the processes. The characters can be displayed when font data in the system memory 16 of the data processing system are cached. The type bit map to a specific character can be moved to a graphics adapter 20 from a cache, by utilizing such a permanent move instruction that can also be utilized by a CPU 14. The characters are moved to the adapter 20, through a fixed scanning line base, containing all character strings in the entire width of the character or in one line.
