PURPOSE:To attain miniaturization of the generator, to attain low power consumption and to reduce the cost by using a dual port storage circuit so as to decrease number of control circuits. CONSTITUTION:A dual port storage circuit 4 is an IC having two independent ports and each port of left and right sides is set to either a data write use or a data read use. The setting is implemented by using a control signal C4 and a memory area is switched alternately to attain data write and readout by applying respectively timing signals T1, T2 inverted at a same period generated from a timing generating circuit 5 to the most significant digit of an address input of the dual port storage circuit 4. Since the dual port storage circuit 4 is used in this way, number of control circuits is saved and the generator is made small in size, the power consumption is decreased and the cost is reduced. |
