Abstract: An H.265 encoding device is described. The encoding device may include a preprocessing module; a coarse selection module; and a precise comparison module. The preprocessing module is configured to divide a current frame from an original video into multiple CTU blocks. The coarse selection module is configured to divide a CTU block based on multiple partition modes, and perform inter-prediction and intra-prediction and generate a prediction information corresponding to the partition modes. The precise comparison module is configured to perform cost comparison, select a partition mode with the lowest cost, generate entropy coding information and reconstruction information based on the selected partition mode and its corresponding encoding information.

Abstract: An image-processing unit for an electronic device is disclosed. The image-processing unit may include a digital signal processor (DSP), a first control interface configured for receiving an AP-instruction from an application processor (AP) external to the image-processing unit, and a second control interface configured for transmitting an intermediary-instruction generated by DSP based on the AP-instruction. The image-processing unit may further include a first data interface configured for receiving sensor-data generated in response to the intermediary-instruction by a sensor external to the image-processing unit, and a second data interface configured for bi-directionally transmitting intermediary-data to the AP or receiving AP-data from the AP, wherein the intermediary-data is generated by the DSP based on the sensor-data.

Abstract: A method for storing data related to video decoding is described. A video-decoding device may divide a video image into a plurality of coding units (CUs). Each of the plurality of CUs has a horizontal coordinate and a vertical coordinate. The video-decoding device may retrieve a first tidbit associated with a first CU from a one-dimensional storage structure. The first CU is adjacent to an un-decoded second CU. The first tidbit is generated during decoding of the first CU and stored in the one-dimensional storage structure based on a first storage index calculated using the first CU's horizontal and vertical coordinates. The video-decoding device may further decode the second CU based on the first tidbit, and store a second tidbit associated with the second CU in the one-dimensional storage structure based on a second storage index calculated using the second CU's horizontal and vertical coordinates.
