  • Patent number: 11985324
    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.

  • Publication number: 20240153895
    Abstract: Semiconductor dies of a semiconductor die package are directly bonded, and a top metal region may be formed over the semiconductor dies. A plurality of conductive terminals may be formed over the top metal region. The conductive terminals are formed of copper (Cu) or another material that enables low-temperature deposition process techniques, such as electroplating, to be used to form the conductive terminal. In this way, the conductive terminals of the semiconductor die packages described herein may be formed at a relatively low temperature. This reduces the likelihood of thermal deformation of semiconductor dies in the semiconductor die packages. The reduced thermal deformation reduces the likelihood of warpage, breakage, and/or other types of damage to the semiconductor dies of the semiconductor die packages, which may increase performance and/or increase yield of semiconductor die packages.

  • Publication number: 20240136346
    Abstract: A semiconductor die package includes an inductor-capacitor (LC) semiconductor die that is directly bonded with a logic semiconductor die. The LC semiconductor die includes inductors and capacitors that are integrated into a single die. The inductors and capacitors of the LC semiconductor die may be electrically connected with transistors and other logic components on the logic semiconductor die to form a voltage regulator circuit of the semiconductor die package. The integration of passive components (e.g., the inductors and capacitors) of the voltage regulator circuit into a single semiconductor die reduces signal propagation distances in the voltage regulator circuit, which may increase the operating efficiency of the voltage regulator circuit, may reduce the formfactor for the semiconductor die package, may reduce parasitic capacitance and/or may reduce parasitic inductance in the voltage regulator circuit (thereby improving the performance of the voltage regulator circuit), among other examples.
