Abstract: Disclosed techniques relate to power management by work distribution circuitry. In some embodiments, a graphics processor includes first and second graphics processor sub-units that respectively include distributed work queue circuitry configured to store graphics work and shader circuitry configured to execute instructions specified by stored graphics work in the sub-unit's distributed work queue circuitry. In some embodiments, work control circuitry includes queue access circuitry to access graphics work in multiple queues and distribution circuitry to assign portions of respective sets of graphics work accessed from the multiple queues to the first and second graphics processor sub-units for execution. In some embodiments, tracking circuitry tracks status of assigned sets of graphics work.

Abstract: Disclosed embodiments relate to submitting tasks to a graphics processor directly by a host processor. In some embodiments, a graphics processor includes control circuitry that schedules and distributes portions of sets of assigned graphics work to multiple different graphics processor sub-units. A processor may execute a driver program for the graphics processor and a program that coordinates with the driver program to send work to the graphics processor, including to: store, in memory circuitry, configuration register data and queued sets of graphics work to be executed by the graphics processor and transmit a signal, to the control circuitry of the graphics processor, to change status of queued sets of graphics work in the memory circuitry. In response to the signal, the control circuitry may schedule and distribute the queued sets of graphics work. This scheduling may be performed without assistance of a firmware processor, which may improve overall performance.

Abstract: The application describes a method and apparatus for decoding voice speech. The method may include receiving encoded data including linear predication coding (LPC) coefficients, an indication of a fixed codebook (FCB), and an indication of an adaptive codebook (ACB). The encoded data may be decoded into a excitation signal. A spectral analysis may performed on the excitation signal. A time envelope of the excitation signal may be applied to a white noise signal and filtered to obtain a complementary noise signal. The complementary noise signal may be summated with the excitation signal to recover a modulated signal. The application also describes a method and apparatus for decoding unvoiced speech.

Abstract: Methods and systems are described for encoding voice speech. A method may include receiving, by an audio encoder, an audio signal comprising a plurality of subframes; determining, for a first subframe of the plurality of subframes, a number of fixed codebook (FCB) pulses according to a rate distortion criteria; selecting, in the subframe, a first set of one or more FCB pulses across a time domain and according to the determined number of FCB pulses; and generating a FCB signal based on the selected first set of FCB pulses.

Abstract: Systems and processes for removing sulfur compounds from a hydrocarbon stream. Sulfur compounds are extracted from a hydrocarbon feed stream with a caustic stream to provide a treated hydrocarbon stream and a rich caustic stream. The sulfur compounds in the rich caustic stream are oxidized in the presence of a catalyst to provide a lean caustic stream. The lean caustic stream is returned to extract sulfur from the hydrocarbon stream. Data such as a concentration of sulfurs species and degree of caustic saturation with the sulfur species in the rich caustic stream may be provided by a sensor, compared against other real-time or historical data and used to provide a recommended adjustment to process conditions associated with an extraction unit, or an oxidation unit, or both.

Abstract: Adsorbent compositions are described. The adsorbent compositions include a metal oxide/mixed metal oxide component, a zeolite component, a metal carbonate component, and optionally a binder. The adsorbent compositions provide high inorganic and organic chloride capacity, controlled acidity, low polymerization/green oil formation, improved hydrothermal stability and mechanical properties including crush strength, increased adsorbent life, and fewer plugging byproduct-formation concerns. Methods of removing organic chlorides and inorganic chlorides from a process fluid using the adsorbent compositions are also described.

Abstract: The present disclosure generally relates to a flow reactor system (100) and a flow reaction method (200). The flow reactor system (100) comprises liquid pumps (110) for communicating liquid reagents based on a set of flow conditions, a fluid pump (200) for communicating a carrier fluid that is immiscible with the liquid reagents; a fluidic mixer (130) for mixing the liquid reagents into a liquid mixture, a measurement device (150) for measuring properties of liquid plugs (140) discharged from an outlet (136) of the fluidic mixer (130); and a control module configured for controlling the liquid pumps (110) and adjusting the flow conditions based on the measured properties of the liquid plugs (140), wherein the liquid plugs (140) are representative of different flow conditions.

Abstract: Techniques for modifying video data to be displayed using a particular output device include receiving initial video data that includes a first set of pixels. A focal region within the pixels is determined automatically or through user input. Viewing data is generated based on the focal region. The viewing data indicates a boundary of a subset of the pixels of the initial video data. The subset has at least one dimension smaller than a corresponding dimension of the first set of pixels. The initial video data is modified, based on the viewing data, to form modified viewing data that includes the subset of pixels and the focal region. The modified video data may then be output using a display having different dimensions or other characteristics than a device used to output the initial video data.
