  • Patent number: 10778980
    Abstract: An entropy decoding apparatus includes an entropy decoding circuit, a pre-fetch circuit, and a context pre-load buffer. The pre-fetch circuit pre-fetches at least one candidate context for entropy decoding of a part of an encoded bitstream of a frame before the entropy decoding circuit starts entropy decoding of the part of the encoded bitstream of the frame. The context pre-load buffer buffers the at least one candidate context. When a target context actually needed by entropy decoding of the part of the encoded bitstream of the frame is not available in the context pre-load buffer, the context pre-load buffer instructs the pre-fetch circuit to re-fetch the target context, and the entropy decoding circuit stalls entropy decoding of the part of the encoded bitstream of the frame.

  • Patent number: 10771163
    Abstract: A decoding apparatus is used for decoding region of interest (ROI) regions in an image, and includes a storage device, a pre-processing circuit, a decoding circuit, and an information fetching circuit. The pre-processing circuit performs a syntax pre-parsing operation upon a bitstream to obtain necessary information of the ROI regions, and stores the necessary information into the storage device. The decoding circuit performs a decoding operation upon the bitstream to decode the ROI regions, wherein the decoding operation includes syntax parsing of the bitstream. The information fetching circuit reads and analyzes the necessary information, and delivers at least a portion of the necessary information to the decoding circuit. A processing time of obtaining necessary information of one ROI region at the pre-processing circuit overlaps a processing time of decoding another ROI region at the decoding circuit.

  • Publication number: 20200101582
    Abstract: A system controls a flow of a chemical mechanical polish (CMP) slurry into a chamber to form a slurry reservoir within the chamber. Once the slurry reservoir has been formed within the chamber, the system moves a polishing head to position and force a surface of a wafer that is attached to the polishing head into contact with a polishing pad attached to a platen within the chamber. A wafer/pad interface is formed at the surface of the wafer forced into contact with the polishing pad and the wafer/pad interface is disposed below an upper surface of the slurry reservoir. During CMP processing, the system controls one or more of a level, a force, and a rotation of the platen, a position, a force and a rotation of the polishing head to conduct the CMP processing of the surface of the wafer at the wafer/pad interface.
