US Patent:

6477170, Nov 5, 2002

Filed:

May 21, 1999

Appl. No.:

09/315974

Inventors:

Jing Lu - Sunnyvale CA
Ching Yu - Santa Clara CA

Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA

International Classification:

H04L 1240

US Classification:

370402, 370428, 375356

Abstract:

A method and apparatus for interfacing a central processing unit to a network switch with an external memory that transfers data to the network switch at a different clock speed than transfers of data to the central processing unit provides an interlocking mechanism to prevent overwriting of data and underflows from occurring. The interlocking of the state machines, accomplished by the idling and advancing of a processor state machine and an external memory state machine, prevents either one of the separate state machines from outrunning the other state machine.

Appl. No.:

10/910002

Inventors:

David Ma - San Jose CA, US
Jing Lu - Santa Clara CA, US

Assignee:

Clarinet Systems, Inc. - Fremont CA

International Classification:

G06F015/16
H04Q007/20

US Classification:

709250000, 709246000

Abstract:

A system and method are provided for uploading photographic data from a wireless device, where the process includes the receiving of a data packet from a mobile phone having digital photograph data and a header configured under a first format with the communication interface, re-configuring the received data packet under a second format with the communication interface, and transmitting the re-configured data packet to a destination device.

Appl. No.:

10/922534

Inventors:

David Ma - San Jose CA, US
Jing Lu - Santa Clara CA, US

Assignee:

Clarinet Systems, Inc. - Fremont CA

International Classification:

H04B007/15

US Classification:

455456600

Abstract:

A system is provided for use in a communication interface for communication between a wireless device and the communication interface to gather local and proximal information. The communication interface is configured to communicate with other devices communicating with a network and configured to facilitate data communication between the wireless device and other devices connected to the network to retrieve and otherwise consume information pertinent to a particular location. A wireless device may then receive a packet having an embedded information address and command from a wireless device that is enabled with a protocol to establish a communication link with an application server, establish a communication link with the application server, retrieve localized information from the application server according to the received embedded command and forward the location related data to the wireless device.

Assignee:

LSI Corporation - Milpitas CA

International Classification:

G11B 5/09

US Classification:

360 49, G9B 5033

Abstract:

A hard disk drive or other storage device comprises a storage medium, a read head configured to read data from the storage medium, and control circuitry coupled to the read head and configured to process data received from the read head. The control circuitry comprises read channel circuitry that includes a low-density parity check decoder or other type of decoder.Power management circuitry associated with the read channel circuitry is configured to detect a power control condition of the read channel circuitry and to control insertion of idle clock cycles in a clock signal supplied to the decoder responsive to the detected power control condition. For example, the read channel circuitry may comprise a clock generator configured to gate the clock signal responsive to a control signal from the power management circuitry.

Abstract:

Methods and apparatus for managing stack data in multi-core processors having scratchpad memory or limited local memory. In one embodiment, stack data management calls are inserted into software in accordance with an integer linear programming formulation and a smart stack data management heuristic. In another embodiment, stack management and pointer management functions are inserted before and after function calls and pointer references, respectively. The calls may be inserted in an automated fashion by a compiler utilizing an optimized stack data management runtime library.
