PURPOSE:To enhance the process efficiency at the arithmetic control part for the system which controls the delay process for the mimic device of underwater propagation of the acoustic signals, by sending sequentially the data stored in the memory to the next memory and at the same time reading out the data sent sequentially through the direct access. CONSTITUTION:Memory 4 contains memories 41-4n comprising plural blocks which memorize the delay data sent from arithmetic control part 1 in the order of the generation time; and timer part 2 generates the transfer signals via the synchronous signals sent from control part 1. Furthermore, transfer control part 3 is provided to send sequentially the contents of memories 41-4n within memory 4 via the transfer signals from part 2, along with memory control part 5 where the mimic data memorized in memory 4 is read and written through the direct access given from control part 1. And the reading signals are transmitted directly to control part 5 from part 1 for reading of the delay data, and thus the contents of memory 4 memorized via part 5 and in the order of the delay time is read out directly. |
