Abstract

PURPOSE: To decrease the frequency of access to a memory by transferring information regarding the addresses of plural characters in blocks and storing it in a buffer for serial transfer, and reading it out at each time when a raster of a scanning type display unit crosses one character. CONSTITUTION: A block transfer means 13 transfers the information regarding the addresses of plural characters, arrayed along a scanning line, in blocks and stores it in the buffer 12 for serial transfer. This information after being stored temporarily in a buffer 14 is read out by a read means 16 each time a raster of the scanning type display unit crosses one character and then supplied to the address terminal of the memory 11 together with a scan address, so that graphic information is read out of the memory 11. Therefore, it is not necessary to read the address information of a character out of the memory 11 each time one character is scanned. Consequently, the frequency of access to the memory 11 can be decreased.
