  • Publication number: 20180329371
    Abstract: A data processing system includes a buffer, a design under checking (DUC), and a self-checking circuit. The buffer is used to buffer data generated from a source device. The DUC is used to perform a designated function upon data read from the buffer when operating under a normal mode. The self-checking circuit is used to apply logic functional checking to the DUC when the DUC operates under a self-checking mode. When the DUC operates under the self-checking mode, the buffer keeps buffering data generated from the source device.

    Abstract: A method and apparatus of sharing an on-chip buffer or cache memory for a video coding system using coding modes including Inter prediction mode or Intra Block Copy (IntraBC) mode are disclosed. At least partial pre-deblocking reconstructed video data of a current picture is stored in an on-chip buffer or cache memory. If the current block is coded using IntraBC mode, the pre-deblocking reconstructed video data of the current picture stored in the on-chip buffer or cache memory are used to derive IntraBC prediction for the current block. In some embodiments, if the current block is coded using Inter prediction mode, Inter reference video data from the previous picture stored in the on-chip buffer or cache memory are used to derive Inter prediction for the current block. In another embodiment, the motion compensation/motion estimation unit is shared by the two modes.

  • Patent number: 9912968
    Abstract: A decoding apparatus has an arithmetic decoder and a controller. A counter logic of the controller generates a first statistics result according to a first syntax element decoding result. A control logic of the controller instructs the arithmetic decoder to perform a first scan procedure at least once to generate the first syntax element decoding result of transform coefficients of a transform coefficient block, controls a repetition number of a second scan procedure based at least partly on the first statistics result, and instructs the arithmetic decoder to perform the second scan procedure at least once to generate a second syntax element decoding result of the transform coefficients. The first scan procedure decodes a first coded syntax element of one transform coefficient when performed by the arithmetic decoder once. The second scan procedure decodes a second coded syntax element of one transform coefficient when performed by the arithmetic decoder once.
