Filed:

Sep 27, 2000

Appl. No.:

09/671554

Inventors:

Daniel G. Jacobs - Meridian ID

Assignee:

Cypress Semiconductor, Inc. - San Jose CA

International Classification:

G06F 1338

US Classification:

710315, 710 22, 710 35

Abstract:

Methods and apparatus for remotely controlling an ATA device via a packet-based interface are disclosed. In one implementation, a remote host constructs command blocks corresponding to the ATA register-delivered commands that it would like executed. These command blocks are packetized and transported to a packet-to-ATA format bridge. At the bridge, each command block is parsed, and appropriate ATA read or write register commands are performed. The bridge performs requested data transfers via the packet-based interface. This embodiment can allow a non-ATAPI ATA device to connect externally to a host computer, e. g. , via a USB plug-and-play packet interface. This can provide inexpensive and portable mass storage capability that does not require internal mounting or external routing of the short ATA cables that are intended for internal use only. Although the host can have access to full ATA register-delivered functionality, it is also freed from the overhead of direct communication with an asynchronous ATA device, including interrupts and polling of that device.

International Classification:

G06F 13/36
G06F 13/00

US Classification:

710311, 710315, 719327

Abstract:

ATA devices, such as mass storage units, have increasingly larger storage sizes that use larger configuration register sizes. A command block format allows the USB/ATA bridge circuit to be used with ATA devices with larger registers and at the same time operates with earlier ATA command block formats.

Inventors:

Daniel G. Jacobs - Meridian ID, US

Assignee:

Cypress Semiconductor Corp. - San Jose CA

International Classification:

G06F 3/00

US Classification:

710 14, 710305, 710306

Abstract:

A power control signal controls a low-power mode, a USB connection, and an asynchronous reset function for a bridge circuit. Another power control signal controls both a high power mode and a low power mode for an attached device. The two power control signals reduce the number of pins required on the bridge circuit for controlling its own power related operations and power related operations of the attached device.
