Abstract: A method and processor for real-time frame processing of a sequence of frames, focusing on motion vector determination, decision metric calculation, and selective triggering of modes for frame processing. It involves calculating motion vectors and their metrics based on pixel displacement and gradient magnitude between consecutive frames to decide on the most appropriate processing mode-copying, generating via neural networks, or rendering using GPUs. The method adapts over time by adjusting thresholds for motion vector metrics, employing decay functions to refine the decision-making process for subsequent frames. This adaptive approach aims to optimize frame generation and rendering quality in dynamic sequences, providing a sophisticated method for managing and enhancing visual media in real-time applications. The processor is configured to execute these steps, adjusting its operations as it processes more frames, ensuring efficient and high-quality visual outputs.

Abstract: Provided are a duty cycle calibration circuit and method, a chip, and an electronic device. In the duty cycle calibration circuit, through a counting clock signal having a higher clock signal frequency than a calibration clock signal, a counting unit is configured to acquire a number of counting pulses generated in a high-level state and a low-level state of the calibration clock signal within a preset counting period, so as to obtain an actual duty cycle of the calibration clock signal. Compared with a method of acquiring a duty cycle of a calibration clock signal by comparing the calibration clock signal with a reference clock signal, inaccurate measurement of the duty cycle of the calibration clock signal after the reference clock signal is affected can be overcome. Therefore, accuracy of measurement of the duty cycle can be improved, and precision of calibration of the duty cycle can be improved accordingly.
