Abstract: A method and apparatus for optimizing a sequence of operations adapted for execution by a processor is disclosed to include locating an operation, if any, that is next within the sequence of operations and setting a current operation to be that operation. The current operation is processed as follows: a) de-activating, if not already de-activated, a consumed indicator associated with the current operation; and b) when the current operation is of the producer type, then activating, if not already activated, a producer indicator associated with the current operation, and locating a first set of operations, if any, that i) are earlier in the sequence of operations than the current operation, ii) have their associated producer indicator activated, and iii) have their associated consumed indicator de-activated, and then de-activating the producer indicator associated with each operation in the first set.

Abstract: A method of handling a trace to be aborted includes receiving an indication of a trace to be aborted and an indication of an abort reason corresponding to an execution of the trace to be aborted. The trace to be aborted has a trace type associated therewith and includes a sequence of the operations, and represents a sequence of at least two of the instructions. The method further includes identifying a corrective action based at least in part on the type of the trace to be aborted and on the abort reason, not taking into account a correspondence between the at least one operation that caused the execution to be aborted and the at least one instruction that the at least one operation at least in part represents. A next trace and its trace type is determined for execution, where the determining is based on the trace to be aborted and on the corrective action.

Abstract: Various embodiments of the present invention are directed to precision control system for spacecraft gimbaled payloads. Embodiments of the invention provide an innovative technique of calibrating gimbals disturbances to directly canceling gimbal control disturbances. Such a calibration system includes a receiver for receiving telemetry data for pointing a payload, a processor for calculating a disturbance parameter vector for a gimbal disturbance model with the telemetry data and a transmitter for transmitting the disturbance parameter vector to compensate for pointing error when applied in pointing the payload. The gimbal disturbance model comprises a harness stiffness term, a disturbance harmonics term and at least one friction hysteresis term. The telemetry data may be time matched prior to calculating the disturbance parameter vector.

Abstract: A/V content creation, editing and publishing is disclosed. Speech recognition can be performed on the A/V content to identify words therein and form a transcript of the words. The transcript can be aligned with the associated A/V content and displayed to allow selective editing of the transcript and associated A/V content. Keywords and a summary for the transcript can also be identified for use in publishing the A/V content.

Abstract: Systems and/or methods are described that enable multi-threaded multimedia processing. These systems and/or methods may, in some embodiments, allocate threads for components of a multimedia pipeline based on input/output characteristics of the components. These systems and/or methods may also allocate threads and priorities for those threads based on a relative importance given components of two or more multimedia pipelines.

Abstract: Briefly and not exclusively, systems, methods, and articles are described for lowering the gain of the first bands of an equalizer. The gain of the first bands of the equalizer are lowered in response to a user adjusted raised gain in the second band of the equalizer. The system includes a gain calculator to determine the lowered first band gains. In one implementation, the gain calculator is configured to determine the lowered first band gains so that the overall power represented by the equalizer audio output signal does not increased. In one implementation, the gain calculator is configured to determine the lowered first band gains so that the overall volume represented by the equalizer audio output signal increases a fraction of the increased volume caused by the raised second band gain.
