Appl. No.:

12/855397

Inventors:

Konstantin L. Vodopyanov - San Jose CA, US
Samuel T. Wong - Lexington MA, US

Assignee:

The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA

International Classification:

G02F 2/02

US Classification:

359330

Abstract:

Certain embodiments relate to and involve producing broadband phase-locked frequency combs in the near-infrared and mid-infrared spectral ranges. One such embodiment is directed to a system, with a pump laser and an optical parametric oscillator (OPO) resonator, that is configured to produce broad-bandwidth frequency combs in the near-infrared and mid-infrared frequency ranges. The pump laser is configured to produce femtosecond pulses of light having a pulse repetition rate. The optical parametric oscillator (OPO) resonator that is coupled to the pump laser for facilitating synchronous OPO pumping by matching a roundtrip time of the pulses of light within the OPO resonator with the pulse repetition rate of the pump laser. Among other more specific aspects, the OPO resonator can include a nonlinear optical gain element to provide broad-bandwidth parametric amplification, and optical elements to direct the pulses of light from the femtosecond laser to the nonlinear gain element and to direct subharmonic frequencies of the light out of the optical cavity.

International Classification:

H04Q007/00

US Classification:

455/419000, 455/553100

Abstract:

For a processor-based device capable of network communications, a workload associated with a wireless link to a network may be partitioned into software and hardware implementable portions based on a link communication profile. In response to a different link communication profile, the workload may be re-configured to simultaneously support another wireless link protocol different than that of the configured wireless link.

Appl. No.:

12/006250

Inventors:

Ning Lu - Folsom CA, US
Samuel Wong - San Jose CA, US
Hong Jiang - El Dorado Hills CA, US
Brian Rauchfuss - Shingle Springs CA, US

International Classification:

H04N 7/26

US Classification:

37524011

Abstract:

In accordance with some embodiments of the present invention, distortion may be calculated using hardware for purposes of motion estimation. The distortion may be determined in the frequency domain. In some embodiments, a modified Haar wavelet transform may be utilized. The penalty in terms of the number of motion vectors may be determined for each location to achieve better distortion in some embodiments. A look up table may be utilized to determine an acceptable penalty. In some cases, the user can input information about an acceptable penalty.

International Classification:

G06F 12/02

US Classification:

711173, 711E12002

Abstract:

A method, computer program product, and system for dynamically distributing data for parallel processing in a computing system, comprising allocating a data buffer to each of a plurality of data partitions, where each data buffer stores data to be processed by its corresponding data partition, distributing data in multiple rounds to the data buffers for processing by the data partitions, where in each round the data is distributed based on a determined data processing capacity for each data partition, and where a greater amount of data is distributed to the data partitions with higher determined processing capacities, and periodically monitoring usage of each data buffer and re-determining the determined data processing capacity of each data partition based on its corresponding data buffer usage.

Inventors:

Samuel Wong - Santa Clara CA, US
Scott W. Cheng - Folsom CA, US
Mohmad I. Qurashi - Orangevale CA, US

International Classification:

H04N 7/26

US Classification:

37524002

Abstract:

CABAC coefficient decoding may be increased to two bins per clock. Since coefficients comprise most of the bitstream, this improvement almost doubles the CABAC decoding for a low quantization parameter bitstream (with lots of coefficients).

International Classification:

H04N 7/26

US Classification:

37524001

Abstract:

Systems, devices and methods are described including using, during a single clock cycle, one Context-Based Adaptive Arithmetic Coding (CABAC) engine to encode one bin value and another CABAC engine to encode another bin value. The probability state index of each CABAC engine may provided to the other CABAC engine when the bin values are encoded.
