摘要： Techniques are disclosed that involve the processing of audio streams. For instance, a host processing platform may receive a content stream that includes an encoded audio stream. In turn, a graphics engine produces from it a decoded audio stream. This producing may involve the graphics engine performing various operations, such as an entropy decoding operation, an inverse quantization operation, and an inverse discrete cosine transform operation. In embodiments, the content stream may further include an encoded video stream. Thus the graphics engine may produce from it a decoded video stream. This audio and video decoding may be performed in parallel.

摘要： Technologies for multi-factor authentication of a user include a computing device with one or more sensors. The computing device may authenticate the user by analyzing biometric and/or environmental sensor data to determine whether to allow the user access to a computing device. To do so, the computing device may determine reliability scores based on the environment during authentication for each biometric authentication factor used to authenticate the user. Additionally, the computing device may determine a login pattern based on sensor data collected during historical authentication attempts by the user over a period of time. The computing device may apply a machine-learning classification algorithm to determine classification rules, based on the login pattern, applied by the computing device to determine whether to allow the user access to the computing device. Other embodiments are described herein and claimed.

摘要： Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.

摘要： In one embodiment, the present invention includes a method for communicating a request for handling of a fault or exception occurring in an accelerator to a first instruction sequencer coupled thereto. The accelerator may be a heterogeneous resource with respect to the first instruction sequencer, e.g., of a different instruction set architecture. Responsive to the request, the fault or exception may be handled in the first instruction sequencer. Other embodiments are described and claimed.

摘要： An apparatus, system, and method are described for providing real-time capture, processing, and distribution of panoramic virtual reality (VR) content. For example, one embodiment of a graphics processor comprises a video interface to receive a first plurality of images from a corresponding first plurality of cameras; an image rectifier to perform a perspective re-projection of at least some of the first plurality of images to a common image plane to generate a rectified first plurality of images; a stitcher to analyze overlapping regions of adjacent images in the rectified first plurality and to identify corresponding pixels in the overlapping regions and to stitch the adjacent images in accordance with the corresponding pixels to generate a panoramic image comprising a stitched combination of the rectified first plurality of images; and a cylindrical projector to project the panoramic image onto a cylindrical surface to generate a final panoramic video image to be used to implement a virtual reality (VR) environment on a VR apparatus.

摘要： This document discloses one or more systems, apparatuses, methods, etc. for implementing an echo cancellation algorithm for long delayed echo that is created during a wire or wireless voice communications. In an implementation, a WiDi feature in a device during the wire or wireless voice communications may add an additional echo delay in addition to channel multipath delay when an audio sound signal travels from a WiDi component to a microphone of the device. In this implementation, a separate delay estimator is configured to estimate total delay. The estimated total delay is fed back to an adoptive filter component for long delay echo cancellation.
