Abstract: A system comprises an encoder configured to entropy encode a bitstream comprising both compressible and non-compressible symbols. The encoder parses the bitstream into a compressible symbol sub-stream and a non-compressible sub-stream. The non-compressible symbol sub-stream bypass an entropy encoding component of the encoder while the compressible symbol sub-stream is entropy encoded. When a quantity of bytes of entropy encoded symbols and bypass symbols is accumulated a chunk of fixed or known size is formed using the accumulated entropy encoded symbol bytes and the bypass bytes without waiting on the full bitstream to be processed by the encoder. In a complementary manner, a decoder reconstructs the bitstream from the packets or chunks.

Abstract: The use of multiple stimulation frequencies and phases is disclosed to detect touch events on a touch sensor panel in a low-power state. Simultaneously during every frame, a number of rows of the touch sensor panel can be driven with a positive phase of one or more stimulation signals, and the same number of different rows can be driven with the anti-phase of those same stimulation signals. Because the same number of rows are stimulated with the in-phase and anti-phase components of the one or more stimulation signals, the resulting charges injected into a given column cancel each other out. However, a touch event will create an imbalance, and a non-zero charge will be detected. The detection of the touch event can then trigger the system to wake up, activate a panel processor, and perform a full panel scan, where the location of the touch event can be identified.

Abstract: In some implementations, a computing device can detect changes in map data based on device activity data received from a mobile device. For example, the device activity data can include location data that describes locations where the mobile devices have traveled, direction, speed, and/or other data. Based on the received location data, the computing device can determine whether stored map data for a particular area accurately reflects the real world characteristics of the particular area. The device activity data can identify user behavior with respect to the mobile device. For example, the characteristics of a real world geographic area may influence how users use their mobile devices (e.g., which applications are used) in the geographic area. The computing device can analyze the user behavior identified in the device activity data to detect changes in the real world characteristics of the geographic area.

By further example, a wearable device can infer whether a tactile input is a result of an activity, such as exercising, random movement, or collision with an object. The wearable devices can accept or reject the tactile input and determine whether an action associated with the tactile input should be performed.

While displaying an autocorrect user interface for changing a string of characters to a modified string of characters, the device detects an autocorrect input that includes an increase in intensity of a contact above a first intensity threshold while a focus selector is over a respective user interface element in the autocorrect user interface, and then either changes the string of characters to the modified string of characters, or maintains the string or characters, depending on whether the contact has an intensity that meets first predefined criteria with respect to the first intensity threshold and a second intensity threshold that is higher than the first intensity threshold.

Abstract: A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.

Abstract: A method and an apparatus for a memory device including a dynamically updated portion of compressed memory for a virtual memory are described. The memory device can include an uncompressed portion of memory separate from the compressed portion of memory. The virtual memory may be capable of mapping a memory address to the compressed portion of memory. A memory region allocated in the uncompressed portion of memory can be compressed into the compressed portion of memory. As a result, the memory region can become available (e.g. after being compressed) for future allocation requested in the memory device. The compressed portion of memory may be updated to store the compressed memory region. The compressed memory region may be decompressed back to the uncompressed portion in the memory device in response to a request to access data in the compressed memory region.

Abstract: A voxel feature learning network receives a raw point cloud and converts the point cloud into a sparse 4D tensor comprising three-dimensional coordinates (e.g. X, Y, and Z) for each voxel of a plurality of voxels and a fourth voxel feature dimension for each non-empty voxel. In some embodiments, convolutional mid layers further transform the 4D tensor into a high-dimensional volumetric representation of the point cloud. In some embodiments, a region proposal network identifies 3D bounding boxes of objects in the point cloud based on the high-dimensional volumetric representation. In some embodiments, the feature learning network and the region proposal network are trained end-to-end using training data comprising known ground truth bounding boxes, without requiring human intervention.

Abstract: Systems, apparatuses, and methods for efficiently allocating data in a cache are described. In various embodiments, a processor decodes an indication in a software application identifying a temporal data set. The data set is flagged with a data set identifier (DSID) indicating temporal data to drop after consumption. When the data set is allocated in a cache, the data set is stored with a non-replaceable attribute to prevent a cache replacement policy from evicting the data set before it is dropped. A drop command with an indication of the DSID of the data set is later issued after the data set is read (consumed). A copy of the data set is not written back to the lower-level memory although the data set is removed from the cache. An interrupt is generated to notify firmware or other software of the completion of the drop command.

Abstract: Image data for a current image frame may be compensated for transient response variations due to changes to pixel values from one frame to another over time by performing pixel drive compensation. The pixel drive compensation may be performed using a current pixel value and a historical pixel value. The historical pixel value may be the same as a pixel value in the directly previous frame in some conditions, while in other conditions the historical pixel value may be modified from a previous image frame in light of a prior pixel value occurring before the previous image frame. In this way, drive compensation corresponding to image data of a subsequent image frame may be determined based at least in part on a multi-frame history. Even so, the memory bandwidth and/or power consumed to use a multi-frame history to determine a drive compensation may be reduced.

Abstract: In an embodiment, a processor includes a load/store unit that executes load/store operations. The load/store unit may implement a two-level load queue. One of the load queues, referred to as a load retirement queue (LRQ), may track load operations from initial execution to retirement. Ordering constraints may be enforced using the LRQ. The other load queue, referred to as a load execution queue (LEQ), may track loads from initial execution to forwarding of data. Replay may be managed by the LEQ. In an embodiment, the LEQ may be smaller than the LRQ, which may permit the management of replay while still meeting timing requirements. Additionally, the larger LRQ may permit more load operations to be pending (not retired) in the processor, widening the window for out of order execution and supporting potentially higher processor performance.

Abstract: An electronic device may include a display such as a light-emitting diode display. The electronic device may be a head-mounted device that provides a virtual reality or augmented reality environment to a user. To reduce artifacts in the display, a display may be operable in both a normal scanning mode and a partial scanning mode. In the normal scanning mode, every row of the display may be enabled to emit light in each frame. In the partial scanning mode, only a subset of the rows of the display may be enabled to emit light in each frame. The display may have a higher refresh rate in the partial scanning mode than in the normal scanning mode. To ensure uniform transistor stress across the display, the scanning driver for the display may scan the disabled rows in the partial scanning mode even though the rows will not be used to emit light.

Abstract: In an embodiment, an operating system includes a device manager that is a central repository of device information. Device drivers may communicate with the device manager over respective channels, and may request channel identifiers (Cids) to communicate with resources related to the respective devices. The device manager may provide values for resource access (or handles that the resources may use to access values). In an embodiment, the device drivers do not have the ability to allocate resources for a peripheral device. Accordingly, the security of the system may be increased. Furthermore, the resource allocation may be centrally located, simplifying the process of updating resource allocation when needed. Additionally, the device manager may delay response to requests from a given device driver until its dependencies are clear (e.g. other device drivers and hardware initializations). Thus, startup scripts may be avoided in some embodiments.

Abstract: A method and apparatus of a device for resource management by using a hierarchy of resource management techniques with dynamic resource policies is described. The device terminates several misbehaving application programs when available memory on the device is running low. Each of those misbehaving application programs consumes more memory space than a memory consumption limit assigned to the application program. If available memory on the device is still low after terminating those misbehaving application programs, the device further sends memory pressure notifications to all application programs. If available memory on the device is still running low after sending the memory pressure notifications, the device further terminates background, idle, and suspended application programs. The device further terminates foreground application programs when available memory on the device is still low after terminating the background, idle, and suspended application programs.
