Abstract
PURPOSE: To increase the memory throughput for the input/output channel device containing the buffer memory by replacing the data transfer action within the channel device to the high-speed inter-register action.
CONSTITUTION: In case the channel performs the writing action in the data transfer control to the memory for the channel device, the data is transferred from the memory via data bus MDTB1 which connects the memory and the channel device. And the data is ratched to register MIR10 through selector 40 and then shifted to register MOR12. In other words, the writing to buffer BFR14 for the data storage use is carried out through MOR12. Then the data stored in BFR14 is read out to register DOR71 which is connected to the interface to transmit the data to the input/output device from the channel device and then transferred to the input/ output device via the input/output interface.
