Patent Images
1. A control apparatus for controlling data transfer to and/or from storage devices, comprising:
- a first control unit (300-330) for controlling data transfer to and/or from an ATA (Advanced Technology Attachment) compliant parallel storage device (135, 140); and
a second control unit (335, 340) for controlling data transfer to and/or from an SATA (Serial ATA) compliant serial storage device (220, 225), wherein the control apparatus is capable of concurrently performing the data transfer to and/or from said parallel and serial devices.

Abstract
A combined ATA and SATA controller is provided that comprises a control unit for controlling data transfer to and/or from an ATA compliant parallel storage device and a control unit for controlling data transfer to and/or from an SATA compliant serial storage device. The controller can concurrently perform the data transfer to and/or from the parallel and serial devices. By reusing a significant amount of controller hardware, the combined controller can be realized in a cost effective manner.
