Abstract: Techniques and apparatus for swapping a primary power source (e.g., a main battery) while using a secondary power source (e.g., a backup battery or a supercapacitor) to power a portable device. One example integrated circuit (IC) for power management generally includes a first power supply node; a second power supply node; a first port for coupling to a primary power source; a first switch coupled between the first power supply node and the first port; a second port for coupling to a secondary power source; a second switch coupled between the first power supply node and the second port; and a third switch coupled between the first and second power supply nodes. For certain aspects, the IC also includes a third power supply node, a voltage regulator coupled between the first and third power supply nodes, and a fourth switch coupled between the second and third power supply nodes.

Abstract: A device includes a substrate that includes a first layer stack including multiple metal layers and multiple dielectric layers. A first metal layer includes contacts disposed in a first region and configured to electrically connect to a first IC device, via pads disposed in a second region, and traces electrically connected to the first contacts and to the via pads. One or more of the traces extend between a pair of the via pads. The substrate also includes a second layer stack disposed on the second region of the first metal layer. The second layer stack includes a dielectric layer and a second metal layer on the dielectric layer. The second metal layer defines second contacts configured to electrically connect to one or more second IC devices. The second layer stack also includes conductive vias extending between the via pads and the second contacts.

Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU. The apparatus may perform a ray traversal process for a second frame in a set of frames starting at a first node in a plurality of nodes, where a ray in the ray traversal process previously intersected a first primitive in a first frame, where the first primitive corresponds to a first node ID. The apparatus may also detect whether the ray intersects the first primitive in the second frame. Further, the apparatus may store the first node ID for the first node based on the ray intersecting the first primitive in the second frame, or re-perform the ray traversal process for the second frame starting at a root node in the plurality of nodes based on the ray not intersecting the first primitive in the second frame.

Abstract: The present disclosure describes methods, computer-readable media, and apparatuses for operating neural networks. For example, an apparatus may receive a set of sparse weight vectors. The apparatus may perform a sparse computation based on the set of sparse weight vectors. The apparatus may combine sparse weight vectors in response to determining a combined time to perform respective numbers of MAC operations for the sparse weight vectors satisfies a threshold number of clock cycles. The apparatus may operate a neural network based at least in part on one or more partial sums produced in performing the sparse computation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network, a procedure rejection message for non-cellular access at a non-access stratum (NAS) layer, and provide a first congestion indication from the NAS layer to lower layers for non-cellular access based at least in part on the receiving the procedure rejection message. The UE may refrain, at the lower layers, from initiating establishment of a signaling connection based at least in part on the first congestion indication. Numerous other aspects are provided.

Abstract: Methods and techniques are described for enhancing positioning related protocols in order to indicate when one location session is different from another location session. One or more messages provided in a location session by a location server to a user equipment (UE) may include a session indication, such as a session identifier (ID), where a different session ID is provided for each location session. The session indication may be a new session indicator provided in an initial message in a location session or an end session indicator provided in a final message in a location session. An extra message may be sent by the location server indicating that the location session has ended. A correlation ID provided by a network entity to the location server may be included in messages as the session indication, e.g., where a different correlation ID is provided for each location session.

Abstract: Systems and techniques are described herein for processing video data. For instance, a process can include determining a number of rows of pixels for one or more portions of an image. The process can further include obtaining first encoded data for a first portion of the image, decoding the first encoded data to generate first pixel data for the number of rows of pixels of the first portion of the image, outputting the first pixel data for the first portion of the image to a memory, and outputting an indication that the first portion of the image is available.

Abstract: A method for wireless communication by a network node includes transmitting a first group of frames comprising a group of normal slots and one or more first special slots. The method also includes reconfiguring one or more second special slots within a second group of frames scheduled after the first group of frames based on a block error rate (BLER) associated with the group of normal slots failing to satisfy a BLER condition. The method further includes transmitting the second group of frames based on reconfiguring the one or more second special slots within the second group of frames.
