Abstract: Apparatuses, systems and methods for routing requests and responses targeting a shared resource. A queue in a communication fabric is located in a path between the requesters and a shared resource. In some embodiments, the shared resource is a shared address translation cache stored in an endpoint. The physical channel between the queue and the shared resource supports multiple virtual channels. The queue assigns at least one entry to each virtual channel of a group of virtual channels where the group includes a virtual channel for each address translation request type from a single requester of the multiple requesters. When the at least one entry for a given requester is de-allocated, the queue allocates this entry only with requests from the assigned virtual channel even if the empty entry is the only available entry of the queue.

Abstract: Adaptive digital content preprocessing techniques based on a bitrate are described. In an implementation, a parameter of a preprocessing module is set based on a target bitrate. The parameter specifies an amount of preprocessing to be performed in preprocessing digital content. Preprocessed digital content is generated by preprocessing the digital content by the specified amount using the preprocessing module. Encoded digital content is generated by compressing the preprocessed digital content using a compression technique by an encoder. The encoded digital content is then transmitted for communication at the target bitrate.

Abstract: A reporting device communicates with a master device by a first component and a daisy-chained second component. The reporting device receives a signal from the master device via the first component. The signal triggers the reporting device to transmit synchronously a telemetry data packet on the daisy-chained second component when a downstream device is coupled to the second component. The reporting device receives a first header packet having an address of the reporting device, transmits the telemetry data packet to the downstream device, and transmits a second header packet having an address of the downstream device.

Abstract: Systems, apparatuses, and methods for bit budgeting in video encode pre-analysis based on context and features are disclosed. A pre-encoder receives a video frame and evaluates each block of the frame for the presence of several contextual indicators. The contextual indicators can include memory colors, text, depth of field, and other specific objects. For each contextual indicator detected, a coefficient is generated and added with other coefficients to generate a final importance value for the block. The coefficients can be adjusted so that only a defined fraction of the picture is deemed important. The final importance value of the block is used to determine the bit budget for the block. The block bit budgets are provided to the encoder and used to influence the quantization parameters used for encoding the blocks.

Abstract: Systems, apparatuses, and methods for performing adaptive audio mixing are disclosed. A trained neural network dynamically selects and mixes pre-recorded, human-composed music stems that are composed as mutually compatible sets. Stem and track selection, volume mixing, filtering, dynamic compression, acoustical/reverberant characteristics, segues, tempo, beat-matching and crossfading parameters generated by the neural network are inferred from the game scene characteristics and other dynamically changing factors. The trained neural network selects an artist's pre-recorded stems and mixes the stems in real-time in unique ways to dynamically adjust and modify background music based on factors such as game scenario, the unique storyline of the player, scene elements, the player's profile, interest, and performance, adjustments made to game controls (e.g., music volume), number of viewers, received comments, player's popularity, player's native language, player's presence, and/or other factors.

Abstract: Systems, apparatuses, and methods for performing a software override of a power estimation mechanism are disclosed. A computing system includes a plurality of tuned parameters for generating an estimate of power consumption. The tuned parameters are generated based on post-silicon characterization of the system. After deployment, the system executes a plurality of different applications. When launching a particular application, the system loads a corresponding set of override parameters which are used to replace the plurality of tuned parameters. The system generates an estimate of power consumption using the set of override parameters rather than the previously determined tuned parameters. Then while executing the particular application, the system makes adjustments to power and frequency values for the various system components based on the estimate of power consumption.

Abstract: A processor supports secure memory access in a virtualized computing environment by employing requestor identifiers at bus devices (such as a graphics processing unit) to identify the virtual machine associated with each memory access request. The virtualized computing environment uses the requestor identifiers to control access to different regions of system memory, ensuring that each VM accesses only those regions of memory that the VM is allowed to access. The virtualized computing environment thereby supports efficient memory access by the bus devices while ensuring that the different regions of memory are protected from unauthorized access.

Abstract: Methods and apparatus encode image frames using intra-frame prediction by predicting pixels for a block of current pixels, based on a detected spatial pattern of pixel intensity differences among a plurality of neighboring reconstructed pixels to the block of current pixels, and encode a block of pixels of the image frame using the predicted block of reconstructed pixels. Inter-frame prediction is provided by determining whether blocks of pixels in temporally neighboring reconstructed frames corresponding to a candidate motion vector have a pattern of pixel intensity differences among the blocks from temporally neighboring frames. Predicted blocks are produced for a reconstructed frame based on the determined pattern of pixel intensity difference among temporally neighboring frames.

Abstract: Systems, apparatuses, and methods for reducing latency for wireless virtual and augmented reality applications are disclosed. A virtual reality (VR) or augmented reality (AR) system includes a transmitter rendering, encoding, and sending video frames to a receiver coupled to a head-mounted display (HMD). In one scenario, rather than waiting until the entire frame is encoded before sending the frame to the receiver, the transmitter sends an encoded left-eye portion to the receiver while the right-eye portion is being encoded. In another scenario, the frame is partitioned into a plurality of slices, and each slice is encoded and then sent to the receiver while the next slice is being encoded. In a further scenario, each slice is being encoded while the next slice is being rendered. In a still further scenario, each slice is prepared for presentation by the receiver while the next slice is being decoded by the receiver.

The processing device comprises memory and a processor. The processor is configured to receive frames of image data comprising sub-frame portions, schedule a first sub-frame portion of a first frame to be processed by a first layer of the convolutional neural network when the first sub-frame portion is available for processing, process the first sub-frame portion by the first layer and continue the processing of the first sub-frame portion by the first layer when it is determined that there is sufficient image data available for the first layer to continue processing of the first sub-frame portion. Processing on a sub-frame portion basis continues for subsequent layers such that processing by a layer can begin as soon as sufficient data is available for the layer.
