PURPOSE:To reduce the burden of a processing device and to output preliminarily determined patterns successively, by setting output patterns, which are outputted successively from a storage device, in a storage control device and updating stored contents by the output start command issued from the processing device. CONSTITUTION:A memory device 14 having the self-updating function consists of a memory 1 and memory controlling circuit 3, and a CPU2 is connected to the device 14. The control circuit 3 of this device 14 is provided with a timing controlling circuit 4, address controlling circuit 5, data controlling circuit 6, and pattern generator 7. A register group which sets successively outputted output patterns is provided in this generator 7, and an updating pattern signal SP, pattern updating synchronizing signal SR, and data update address signal SA are transmitted from the CPU2 to the generator 7. Successively outputted patterns are updated by the output start command from the CPU2, and thus, the burden of the CPU2 is reduced, and preliminarily determined patterns are outputted successively. |
