Abstract: A cache system is configurable to trade power consumption for cache access latency. When it is desired for a system with a cache to conserve dynamic power, the lookup of accesses (e.g., snoops) to cache tag ways is serialized to perform one (or less than all) tag way access per clock (or even slower). Thus, for an N-way set associative cache, instead of performing a lookup/comparison on the N tag ways in parallel, the lookups are performed one tag way at a time. This take N times more cycles thereby reducing the access/snoop bandwidth by a factor of N. However, the power consumption of the serialized access when compared to ‘all parallel’ accesses/snoops is reduced.

Abstract: The techniques disclosed herein can enable a system to coordinate the processing of object-based audio and channel-based audio generated by multiple applications. The system determines a spatialization technology to utilize based on contextual data. In some configurations, the contextual data can indicate the capabilities of one or more computing resources. In some configurations, the contextual data can also indicate preferences. The preferences, for example, can indicate user preferences for a type of spatialization technology, e.g., Dolby Atmos, over another type of spatialization technology, e.g., DTSX. Based on the contextual data, the system can select a spatialization technology and a corresponding encoder to process the input signals to generate a spatially encoded stream that appropriately renders the audio of multiple applications to an available output device. The techniques disclosed herein also allow a system to dynamically change the spatialization technologies during use.

Abstract: Metrics are defined and collected for an application. The metrics are organized in hierarchical trees with metrics aggregated at each node in the trees. Each tree represents a different permutation of the metrics. A particular metric may occur in more than one tree. A user interface provides a default drill-down that allows users to jump from one metric to another so that only the most useful information is presented to the user. The default drill-down is defined to provide the user with a best practices method to identify and correct problems or errors in the application. Users may modify the default drill-down path.

Abstract: Techniques and systems for applying an ink effect to the drawing of an ink stroke can include absolute age for a digital ink stroke. A digital ink system can identify a reference time from which to represent a current time. The system can generate an absolute age of each ink point of the ink stroke based on the reference time. Then the ink effect can be applied to the ink stroke with a rhythm derived from when the ink stroke was originally drawn by using the absolute age of each ink point. In some cases, the rhythm can be the same rhythm as when the ink stroke was originally drawn. In other cases, the rhythm can be modified based on the rhythm the ink stroke was originally drawn. For example, the original rhythm may be accelerating, decelerating, skewed, compressed, affine, or non-affine.

Abstract: Facilitating recording a trace of code execution using way-locking in a set-associative processor cache. A computing device reserves cache line(s) in set(s) of cache lines of a set-associative cache for caching only locations in the system memory that are allocated to a particular executable entity. During a traced execution of the particular executable entity, the computing device detects that a cache miss has occurred on a location in the system memory that is allocated to a particular executable entity, and that a value at the location of system memory is being cached into one of the reserved cache lines. Based on the value at the location of system memory being cached into a reserved cache line, the computing device logs into a trace data stream at least a portion of the value at the location of system memory being cached into the reserved cache line.

Abstract: Discriminative pretraining technique embodiments are presented that pretrain the hidden layers of a Deep Neural Network (DNN). In general, a one-hidden-layer neural network is trained first using labels discriminatively with error back-propagation (BP). Then, after discarding an output layer in the previous one-hidden-layer neural network, another randomly initialized hidden layer is added on top of the previously trained hidden layer along with a new output layer that represents the targets for classification or recognition. The resulting multiple-hidden-layer DNN is then discriminatively trained using the same strategy, and so on until the desired number of hidden layers is reached. This produces a pretrained DNN. The discriminative pretraining technique embodiments have the advantage of bringing the DNN layer weights close to a good local optimum, while still leaving them in a range with a high gradient so that they can be fine-tuned effectively.

Abstract: User selection of a displayed object is detected. The size of the selected object is identified and compared with a move target size threshold. If the size of the selected object does not meet the move target size threshold, then a user actuatable move handle is displayed in a location displaced from the selected object, on the user interface, but visually connected to the selected object. User actuation of the move handle correspondingly moves the object on the user interface.

Abstract: Methods, systems, and devices are described herein for modifying the monitoring of the health of a data center IP endpoint (such as VM) during live migration of the data center IP endpoint from a source host to a destination host. In one example, the described techniques may include receiving an indication that a virtual machine is going to be live migrated from a source host to a destination host. Next, evaluation of health probe responses originating from the virtual machine may be suspended for a time period. The time period may be selected based on the live migration. The evaluation of the probe responses originating from the virtual machine may be resumed upon completion of the time period. In some cases, a health probe status of the virtual machine may be migrated from the source host to the destination host.

Abstract: Shutdown notification techniques are described in which notifications associated with various applications and functionality of a device are presented in conjunction with a shutdown sequence. In one or more implementations, a shutdown of the device may be initiated automatically in response to low power conditions, device/application errors, restarts, or explicitly by a user. A notification system of a device may be configured to enable designation of particular notifications to show upon shutdown. Notifications to output at shutdown may be selected based upon various criteria including but not limited to selection based on a perceived importance, notification type, particular application(s), and/or particular user contacts. When a shutdown is initiated, a check is performed to determine whether any designated notifications are available.

Abstract: A game controller with haptic Braille chording capability. While a conventional game controller are geared to sighted players, the disclosed controller configurations include various adaptations that provide alternative input and outputs to facilitate game play by sight-impaired or blind users, as well as other users knowledgeable of Braille. A number of paddles may be arranged on a game controller housing so that a player may engage selected ones of the paddles to enable encoding braille characters using the paddles. This input may be used to control a game, enter text into a chat session or take any other action desired. The converse may also occur, where a combination of the paddles may provide haptic feedback detectable by a user holding a game controller so that the paddles encode braille output (or other data), allowing a user to receive output simply by contact with the paddles.
