  • Patent number: 11995471
    Abstract: A resource integration method includes the following steps: a receiving module receives access information from a guest operating system on the host device; the access information is used to determine whether the frame rate is lower than a frame rate threshold; when the receiving module determines that the frame rate is lower than the frame rate threshold, the receiving module transmits an external resource request signal to the receiving module; after the receiving module receives the external resource request signal, a resource management module (which is located in the bridge module) selects an optimal external device from a specific category (among a plurality of categories in a candidate list), and a calculation operation or a storage operation corresponding to the specific category is transmitted to the optimal external device for calculation or storage by the bridge module.

  • Publication number: 20240154014
    Abstract: The present disclosure provides a forksheet structure in a semiconductor device and methods of manufacturing thereof. The forksheet structure according to the present disclosure includes a dielectric wall disposed between two channel regions inside a gate structure and without extending through the sidewall spacers to the source/drain regions. In some embodiments, a cut metal gate (CMG) dielectric structure is formed in the gate structure along with the dielectric walls. A gate dielectric layer is in contact with the dielectric wall. In some embodiments, the dielectric layer surrounds semiconductor channels in the channel region. In other embodiments, the gate dielectric layer surrounds a portion of the semiconductor channels in the channel region, for example forming a ?-shape cross sectional profile around the semiconductor channel.

  • Patent number: 11946733
    Abstract: An image rendering device and an image rendering method are disclosed. For the elements of the image rendering device, a first sensor and a second sensor are configured to sense a target object in a two-dimensional (2D) mode and three-dimensional (3D) mode to generate a first surface-color-signal, a first 3D-depth-signal, a second surface-color-signal and a second 3D-depth-signal respectively. An IR projector is configured to generate an IR-dot-pattern. A processor is configured to control the IR projector to project the IR-dot-pattern on the target object in the 3D mode, and configured to process the first surface-color-signal, the second surface-color-signal, the first 3D-depth-signal and the second 3D-depth-signal to obtain a color 3D model of the target object.
