INTERFACE CONTROLLER AND DATA TRANSFERRING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the efficiency of a system consisting of a device provided with the interface controller and a plurality of controllers. SOLUTION: The interface controller having a function for converting a device provided with an ATAPI interface to an SCSI interface opens a bus by monitoring the command processing time of an ATAPI device. The interface controller stores information on a reception command and information on the state of the device in an internal memory to store information in the internal memory of the interface controller to correspond to the command of the computer.
