Abstract: An artificial intelligence (AI) calculation circuit is provided. The AI calculation circuit can support various integer and floating-point calculations through the adjustment of circuit configuration. Integer multiplication and floating-point mantissa multiplication share the multiplication unit, integer comparison and floating-point comparison share the same comparison unit, integer addition and floating-point addition share the same addition unit.

Abstract: A data compression method for a deep neural network is provided. The data compression method includes following steps. Pleural items of original data are re-mapped according to at least one offset value and a sign value to obtain pleural items of mapped data. A distribution center of the mapped data is aligned with 0 and all of the mapped data are non-negative integers. Pleural data blocks of the mapped data are encoded using at least two encoding modes to generate an encoding data.

Abstract: The present invention provides a system for a video window in a graphics background of a screen. The video window is allowed to be removed anywhere and be scaled up or down. The system comprises a receiving module to receive the video and graphics data and group both of the data in segment, a scaling module to process the scaling by applying the provided recursive pixel-extracting algorithm for the video segment, and an overlapping module to post the scaled video data on the graphics data in accordance with a boundary condition.

Abstract: The present invention provides a method and system for displaying digital video. The CPU configures a space in the main memory for entries to record the displaying information in accordance with a video source in sequence and transfer the corresponding video data of the entries to the main memory. The flip controller informs the display controller to access the video data in the main memory in accordance the displaying information of the entries, and the display controller output the video data in the main memory to display in a screen.
