Abstract

PURPOSE: To increase a rewriting rate with low-priced constitution by rewriting pattern data to be displayed from the 1st pattern memory to the 2nd pattern memory when the pattern data do not reside in the 2nd pattern memory.
CONSTITUTION: Many pattern data are stored in pattern memory 21 and pattern data to be displayed are in pattern memory 22 capable of rewriting faster than memory 21. Then, addresses of stored pattern data to be displayed are stored in address buffer 23 according to display positions; addresses are extracted by display control circuit 24 in the order of diaplay positions and corresponding pattern data, read out from memory 22, are displayed in sequence by display part 25. Next, a check on where or not the pattern data to be displayed reside in memory 22 is made and if not, the pattern data are rewritten from memory 21 to memory 22. Consequently, the rewriting rate can be increased by low-priced constitution.
