Abstract: A process scheduling method and a terminal device are provided. According to the process scheduling method, for a first process with a first tag in a process set, when the first process is instructed to be scheduled, the terminal device prohibits scheduling of the first process. In this way, a CPU of the terminal device does not execute the first process, that is, the CPU does not allocate resources to the first process. Alternatively, the first process is set at the end of a process queue to be scheduled, because the terminal device always executes, from the process queue to be scheduled, a top process in the process queue to be scheduled. In this way, the terminal device has a reduced probability of executing the first process.

In the method disclosed in the embodiments of this application, when the terminal device is in a screen-off state and enters a dormant state, when receiving the data packet sent by the cloud server, the communications chip does not immediately wake up the application processor, and instead first identifies to determine whether the data packet needs to be filtered out, that is, determine whether the process of the application program to which the data packet is to be sent is restricted from data exchange with the cloud server.

Abstract: Exemplary video processing methods and apparatuses for encoding or decoding a current block by inter prediction are disclosed. Input data of a current block is received and partitioned into sub-partitions and motion refinement is independently performed on each sub-partition. A reference block for each sub-partition is obtained from one or more reference pictures according to an initial motion vector (MV). A refined MV for each sub-partition is derived by searching around the initial MV with N-pixel refinement. One or more boundary pixels of the reference block for a sub-partition is padded for motion compensation of the sub-partition. A final predictor for the current block is generated by performing motion compensation for each sub-partition according to its refined MV. The current block is then encoded or decoded according to the final predictor.

Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.

Abstract: Beamforming circuitry for an ultrasound device is disclosed, that may directly calculate the position in receive line space for an incoming ultrasound data sample given the time of flight (ToF) of that ultrasound data sample. In some embodiments, this may be done without initially buffering the ultrasound data sample received from the particular receive datapath multiplexed to the beamforming circuitry. The beamforming circuitry may then associate the ultrasound data sample with that position in receive line space, and in particular, with a memory address corresponding to that location. Thus, when the beamforming circuitry multiplexes between different receive datapaths, it may not need to buffer ultrasound data samples from different receive datapaths prior to saving the data to memory.
