PURPOSE:To access optional length data by connecting a clock of a counter, a load input, a clock of a line counter and a load data input to an external signal input terminal of a frame memory board. CONSTITUTION:A load signal 8 of a counter 1, a clock 9 of the counter 1, a load signal 6 of a line counter 2 and a clock 7 of the line counter 2 are connected to the external signal terminal of a frame memory board. Thus, the frame data of large capacity is accessed by a few signal line and the consecutive data of an optional length is used as the accessible frame memory board.
