Abstract: Virtual Reality (VR) systems, apparatuses and methods of processing data are provided which include predicting, at a server, a user viewpoint of a next frame of video data based on received user feedback information sensed at a client, rendering a portion of the next frame using the prediction, encoding the portion, formatting the encoded portion into packets and transmitting the video data. At a client, the encoded and packetized A/V data is received and depacketized. The portion of video data and corresponding audio data is decoded and controlled to be displayed and aurally provided in synchronization. Latency may be minimized by utilizing handshaking between hardware components and/or software components such as a 3D server engine, one or more client processors, one or more client processors, a video encoder, a server NIC, a video decoder, a client NIC; and a 3D client engine.

Abstract: A processing apparatus is provided that includes an encoder configured to encode current frames of video data using previously encoded reference frames and perform motion searches within a search window about each of a plurality of co-located portions of a reference frame. The processing apparatus also includes a processor configured to determine, prior to performing the motion searches, which locations of the reference frame to reload the search window according to a threshold number of search window reloads using predicted motions of portions of the reference frame corresponding to each of the locations. The processor is also configured to cause the encoder to reload the search window at the determined locations of the reference frame and, for each of the remaining locations of the reference frame, slide the search window in a first direction indicated by the location of the next co-located portion of the reference frame.

Abstract: An apparatus and method for efficiently creating less computationally intensive nodes for a neural network. In various implementations, a computing system includes a memory that stores multiple input data values for training a neural network, and a processor. Rather than determine a bit width P of an integer accumulator of a node of the neural network based on bit widths of the input data values and corresponding weight values, the processor selects the bit width P during training. The processor adjusts the magnitudes of the weight values during iterative stages of training the node such that an L1 norm value of the weight values of the node does not exceed a corresponding weight magnitude limit.

Abstract: The present disclosure is directed a system and method for exploiting camera and depth information associated with rendered video frames, such as those rendered by a server operating as part of a cloud gaming service, to more efficiently encode the rendered video frames for transmission over a network. The method and system of the present disclosure can be used in a server operating in a cloud gaming service to improve, for example, the amount of latency, downstream bandwidth, and/or computational processing power associated with playing a video game over its service. The method and system of the present disclosure can be further used in other applications where camera and depth information of a rendered or captured video frame is available.

Abstract: Systems, apparatuses and methods of adaptively controlling a cache operating voltage are provided that comprise receiving indications of a plurality of cache usage amounts. Each cache usage amount corresponds to an amount of data to be accessed in a cache by one of a plurality of portions of a data processing application. The plurality of cache usage amounts are determining based on the received indications of the plurality of cache usage amounts. A voltage level applied to the cache is adaptively controlled based on one or more of the plurality of determined cache usage amounts. Memory access to the cache is controlled to be directed to a non-failing portion of the cache at the applied voltage level.

Abstract: Systems, methods and apparatuses of processing data of a VR system are disclosed that comprise receiving tracking information which includes at least one of user position information and eye gaze point information. One or more processors may be used to predict, based on the user tracking information, a user viewpoint of a next frame of a sequence of frames of video data to be displayed. Using the prediction, a portion of the next frame of video data to be displayed is rendered at an estimated location in the next frame. A corresponding matching portion in a previously encoded frame is determined based on the estimated location of the portion in the next frame and the portion of the next frame of video data is encoded.
