Abstract
PURPOSE: To prevent the overrun which occurs during the initial section process by partitioning the initial section process given from CPU into the sequence process to send out the command and that to receive the initial status given from the input/output device.
CONSTITUTION: Peripheral unit adaptor 2 is connected to CPU1 via the interface, and control memory 10 executing the control of the CPU itself is provided to CPU1 along with local storage 11 to carry out the channel function to the input/output device connected via adaptor 2. In such data process system, CPU interface register part 12 is installed between CPU1 and adaptor 2. And CPU1 and adaptor 2 are constituted so that they can perform read/write to part 12. Then the first sequence process in which CPU1 sends out the command and the second sequence process to receive the initial status from the input/output device are divided and controlled by I/O control register 16 and interruption control circuit 17.
