Abstract

PURPOSE: To reduce the number of interrupting processings in case of the control data such as bytes, by coupling the address to be executed with the set CPU and channel, while the instruction end report executing the command group is made from the channel.
CONSTITUTION: The channel address word 4 is prepared for CPU1 and the channel control words 5-0,5-1... are prepared at the address location described in the address word 4 and CPU1 makes the start instruction to the channel 2. The channel 2 reads out the channel address word 4 based on this start instruction to start the execution of the command group 6 prepared at the control words 5-0,5-1..., and the instruction end report is executed to CPU1 after the end of execution. In this channel control, while the instruction end report is made, CPU1 and the channel 2 are coupled and the execution of the command group 6 is stopped on the way of execution of the command group 6 to enable the end report of instruction and to reduce the number of interruption processings of the control data such as bytes.
