Abstract

PURPOSE: To make it possible to respond rapidly to an I/O command from CPU by storing previously state information for an I/O controller in an I/O processing unit and updating this information successively.
CONSTITUTION: I/O processing unit 2 monitors state information and connection request for I/O controller 3, and state information is always updated and is taken into I/O processing unit 2. In this case, when connection request is not generated, state information for another I/O controller is taken in; and when connection request is generated, state information for another I/O controller is taken in after executing a required processing for the I/O controller. Then, state information for the I/O controller is held in I/O processing unit 2, so that it is possible to respond to an I/O command from CPU 1 rapidly.
