ABSTRACT:
The address generation unit 166 generates a write address for each picture data to be written in the frame memory 169. The memory control unit 165 writes picture data which have the same Y address and consecutive X addresses to the first bank and the second bank alternately per one-page mode length, and further writes picture data which have the same X address and adjacent Y addresses to the different banks. The memory control unit 165 determines a minimum area which consists of an odd number of page mode lengths and includes picture data of a square area having the same Y address, and reads the determined area from the two storage areas alternately per Y address.
