Abstract
PURPOSE: To make the level change of queue possible to give flexibility to a data processing unit, by providing a queue-NO in a channel control block in the data processing unit.
CONSTITUTION: The main memory of the data processing unit which has a channel for I/O control and controls peripheral devices under the control of this channel is provided with a channel control block which has control information corresponding to a peripheral device. Then, a queue number field where plural levels are prepared and a lower level has a priority higher than others and the priority of the termination queue interrupt corresponding to each lecel is formed is provided in this channel control block.
