Abstract: The disclosure relates to tuning configuration parameters for graphics pipeline for better user experience. A device for graphics processing, comprising: hardware engines; a graphics pipeline at least partly implemented by the hardware engines; and a tuner, coupled to the hardware engines and the graphics pipeline, the tuner to: collect statuses of the device during runtime for a previous frame; determine configuration parameters based on the collected statuses, the configuration parameters associated with three-dimensional 3D rendering, pre-processing and video encoding of the graphics pipeline; and tune the graphics pipeline with the determined configuration parameters for processing a next frame.

Abstract: Determination of the impulse position in a multipath channel in a noisy environment includes dynamically adjusting a threshold value when making comparisons against a signal property level.

Abstract: Data handling dynamically responds to changing noise power conditions to separate valid data from noise. A reference power level acts as a threshold between dynamically assumed noise and valid data, and dynamically refers to the reference power level changing adaptively with the background noise. The introduction of dynamic noise control in VOX (Voice Activated Transmission) improves a VOX device operation in a noisy environment, even when the background noise profiles are changing. Processing is on a frame by frame basis for successive frames. The threshold is adaptively changed when a comparison of frame signal power to the threshold indicates speech or the absence of speech in the compared frame repeatedly and continuously for a period of time involving plural successive frames having no valid speech or noise above the threshold to correspondingly reduce or increase the threshold by changing the threshold to a value that is a function of the input signal power.

Abstract: Embodiments of a system, method and computer program product for providing content to a remote device are described. In one embodiment, a request to establish a link is received from a remote device via an access point in a set of access points that define a service area. A link with may then be established the remote device. An identifier may also be associated with the remote device for the newly established link so that subsequent communications made via the link can include the identifier. Communications made via the link can be monitored in the service area utilizing the identifier to determine the location of the remote device. Based on determined location of the remote device, content may be selected and sent to remote device for subsequent presentment.

Abstract: The present invention provides a method and system to improve the cookbook search algorithm used in a coding/decoding device or routine. The codebook search algorithm is performed by a processing system that allows for parallel execution of instructions, for example a DSP. An embodiment of the present invention provides a method for coding of a first waveform. First a plurality of vectors determined from a plurality of waveforms is stored in a memory. Next a minimum weighted error using a plurality of filter coefficients and the plurality of vectors is determined. The minimum weighted error gives a closest match between the first waveform and a second waveform synthesized from a selected vector of the plurality of vectors. Then an indication of said selected vector is provided as part of a code of the first waveform.

Abstract: The present invention provides a method and apparatus for performing an inverse modified discrete cosine transform (IMDCT) on at least one block of spectral coefficients representing an information signal in the frequency domain. The IMDCT provides an IMDCT output including at least one block of processed samples in the time domain. The new and novel method of the present invention includes converting spectral coefficients in the block of spectral coefficients to provide a block of frequency domain processed complex samples and processing the block of frequency domain processed complex samples into the block of processed samples in the time domain.
