Abstract: Certain aspects of the present disclosure provide techniques and apparatus for scheduling execution of machine learning model operations on a multiprocessor computing device. The method generally includes during execution of operations in a first portion of a machine learning model on a first processing unit of the computing device, measuring a temperature for each of a plurality of locations on the computing device. It is determined that a temperature measured for the first processing unit exceeds a threshold temperature. Based on one or more operating parameters for the computing device, a second processing unit of the computing device is selected to use in executing operations in a second portion of the machine learning model. Execution of operations in the second portion of the machine learning model on the second processing unit is scheduled.

Abstract: Systems, methods, and apparatus for controlling radio frequency (RF) interference at a mobile communication device are described. A data communication apparatus has a wireless transceiver configured to transmit and receive RF signals, a bus interface circuit coupled to a serial bus and configured for operation as a display serial interface (DSI), and a controller. The controller is configured to receive a measurement of a reference signal representative of RF signal quality at the mobile communication device, determine whether the measurement of the reference signal indicates that the RF signal quality is less than a minimum RF signal quality level, and reduce signal strength of a transmitter in the bus interface circuit when the RF signal quality falls below the minimum RF signal quality level.

Abstract: Systems, methods, and non-transitory media are provided for dynamically switching frame rates without changing a display refresh rate. An example method can include receiving, from a display device associated with a computing device, a set of control signals indicating a display refresh rate implemented by the display device; adjusting a frame rate associated with application data from one or more applications executed on the computing device; synchronizing, based on the set of control signals, the adjusted frame rate with two or more display refresh cycles, each display refresh cycle being based on the display refresh rate; providing, to the display device, a first frame at the adjusted frame rate, the first frame being generated based on the application data; and displaying the first frame at the display device implementing the display refresh rate.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE) or component thereof. The apparatus may be configured to transmit to a base station a first request to transmit data in a buffer. The apparatus may be further configured to transmit to the base station a second request to transmit the data in the buffer in absence of a grant in response to the first transmit request. The apparatus may be further configured to remain awake for at least a portion of a scheduled discontinuous reception (DRX) sleep state following the transmission of the second request.

Abstract: Method and apparatus for selecting a gamma curve used by a display driver circuit for converting code words provided by a display processing unit to brightness levels based on an operating mode of the computing device. For example, the display processing unit provides code words to the display driver circuit for driving output at a display. Further, the display driver circuit converts the provided code words to analog signal for driving output at the display based on the selected gamma curve.

Abstract: Aspects of the present disclosure provide a simplified solution for proximity detection of an object in a wireless communication that does not require complex hardware to maintain mutual coupling reference signal. Specifically, in accordance with aspects of the present disclosure, the received signal that may include the mutual coupling signal and target signal may be multiplied by itself to extract the delay information associated with the target signal. The techniques outlined here may provide a greater robustness to variations of mutual coupling induced by phone covers, for example, being added by the user.

Abstract: Embodiments include methods and devices for per layer motion adaptive over-drive strength control for a display panel. Various embodiments may include determining motion information associated with a frame layer, determining an over-drive strength factor for the frame layer based at least in part on the motion information associated with the frame layer, and determining whether the over-drive strength factor is associated with computing a content difference. Various embodiments may include, in response to determining that the over-drive strength factor is associated with computing a content difference, performing fragment shading on the framebuffer object for the frame layer to generate an over-drive compensated framebuffer object for the frame layer based at least in part on the over-drive strength factor, and outputting the over-drive compensated framebuffer object for the frame layer to a default framebuffer for rendering on the display panel.
