ABSTRACT:
An interface device using a plurality of IDE Ports is disclosed, in which, in order to process signals of drives having different access times, separate IDE ports are added, so that different IDE ports can be selected in accordance with the respective access times. The interface device has an IDE controller for outputting control signals to control data input and output operations for a drive having a fast access time, a first IDE port with its operation state shifted in accordance with the control signals of the first IDE controller, so as to transmit input and output data, a data transmission path and an address area being assigned in accordance with the state of the input and output data signals, a second IDE controller for outputting control signals to control data input and output operations for a drive having a slow access time, and a second IDE port with its operation state shifted in accordance with the control signals of the second IDE controller, so as to transmit input and output data, a data transmission path and an address area being assigned in accordance with the state of the input and output data signals.
