Device and method for optimization of target host device process handling according to the status and the priority of the target host device process
An input/output device stores host status information about the status of a host, and controls the input/output of data. By referring to the input/output information and the host status information, the device performs optimization control of selecting notification either by an interrupt process or a non-interrupt process. When a notification by the interrupt process is selected, data transfer control is performed to the host, and the data is transferred to the host by an interrupt. When a notification by the non-interrupt process is selected, data transfer control is performed to the host, and notification control is performed to transfer the data to the host by polling.
