Abstract
An I/O system where there is provided a Task Control Processor which provides for the scheduling of the different central processors for the highest priority processes to be run. When an initiate I/O operation is detected, the respective processor is released from the process that it is currently running and can be assigned to the next highest priority process. When the requested I/O operation has been completed, the Task Control Processor is signalled so that the Task Control Processor can put the requesting process back into the priority list of processes to be run by the main central processors.
