PURPOSE:To omit a practical change in microstep by forming CPU corresponding start information storing parts for queuing start information of each CPU in a channel. CONSTITUTION:When plural CPUs 1-0-1-3 start the channel 3 in common, the channel 3 queues and stores respective bits of start information from respective CPUs 1-0-1-3 in the CPU corresponding start information storing parts 6-0-6-3. The channel 3 latches each start and informs the start to a microprocessor 7 in accordance with priority. At that time, the contents of the storing parts 6-0-6-3 are read out correspondingly to the start notification and start information corresponding to the start notification is informed to the microprocessor 7. |
