  • Publication number: 20230421756
    Abstract: In some embodiments, a method maintains a list that is configured to store motion vectors from one or more blocks that have been previously processed in a frame. When a current block is in a first set of positions in the frame, the method resets the list by storing a motion vector with a horizontal component and a vertical component equal to zero in the list. The motion vector with the horizontal component and the vertical component equal to zero from the list is used to transcode the current block. When the current block is not in the first set of positions, the method uses a motion vector from the list to transcode the current block.

  • Patent number: 11836629
    Abstract: A computation unit comprises first, second, and third circuits. The first circuit traverses gradient loss elements gpn and normalized output elements pn and produces an accumulation C. The accumulation C is produced by element-wise multiplying the gradient loss elements gpn with the corresponding normalized output elements pn and summing the results of the element-wise multiplication. The second circuit, operatively coupled to the first circuit, element-wise subtracts the accumulation C from each of the gradient loss elements gpn and produces modulated gradient loss elements gpn?. The third circuit, operatively coupled to the second circuit, traverses the modulated gradient loss elements gpn? and produces gradient loss elements gxn for a function preceding the softmax function. The gradient loss elements gxn are produced by element-wise multiplying the modulated gradient loss elements gpn? with the corresponding normalized output elements pn.

  • Patent number: 11817494
    Abstract: A semiconductor device includes an active layer having an active region, a source electrode, a drain electrode, a gate electrode, a source metal layer, a drain metal layer, and a source pad. The source metal layer and the drain metal layer are electrically connected to the source electrode and the drain electrode, respectively. An orthogonal projection of the drain metal layer on the active layer each forms a drain metal layer region. The source pad is electrically connected to the source metal layer. An orthogonal projection of the source pad on the active layer forms a source pad region overlapping the drain metal layer. An area of an overlapping region between the source pad region and the drain metal layer region is smaller than or equal to 40% of an area of the drain metal layer region.

  • Patent number: 11812208
    Abstract: A method and a device for reducing noise of a wireless-earphone, a wireless-earphone and a computer-readable storage medium are provided. In the method, a first electromagnetic signal from a slave earphone is received, and the first electromagnetic signal is converted to an audio signal. The first electromagnetic signal is obtained by a coil inducing an audio signal acquired by a microphone in the slave earphone. A to-be-denoised earphone is determined based on audio signals acquired by microphones in the earphones. It is determined whether an audio signal acquired by a microphone in the to-be-denoised earphone has a voice feature. Noise reduction processing is performed on the audio signal acquired by the microphone in the to-be-denoised earphone by using a filter in a case that the audio signal acquired by the microphone in the to-be-denoise earphone has the voice feature.

  • Patent number: 11792307
    Abstract: Methods and apparatus for efficient data transfer within a user space network stack. Unlike prior art monolithic networking stacks, the exemplary networking stack architecture described hereinafter includes various components that span multiple domains (both in-kernel, and non-kernel). For example, unlike traditional “socket” based communication, disclosed embodiments can transfer data directly between the kernel and user space domains. Direct transfer reduces the per-byte and per-packet costs relative to socket based communication. A user space networking stack is disclosed that enables extensible, cross-platform-capable, user space control of the networking protocol stack functionality. The user space networking stack facilitates tighter integration between the protocol layers (including TLS) and the application or daemon. Exemplary systems can support multiple networking protocol stack instances (including an in-kernel traditional network stack).
