Abstract
PURPOSE:To minimize influence due to the competition of access requests outputted from both systems and to remove the loss of a waiting time by optionally dividing each of both the systems into segments and controlling respective segments and transferring only renewal segments to the memories of both systems. CONSTITUTION:When a trigger signal A from a port A to a port B is generated, a status control part is started by receiving the trigger signal A. On the other hand, semaphores A for inhibiting the generation of a trigger signal after receiving the initial trigger signal are generated on both the ports A, B. Since the status control part controls and stores the existence of the updating of the memories in each segment, the status control part transfers only an updated segment at the time of its starting. At the time of completing the transfer of one segment, a transfer completion signal TC is informed to a transfer control part.
