摘要： The present disclosure relates to methods and apparatus for frame processing. Aspects of the present disclosure can adjust or scale a CPU frequency value in order to avoid potential janks. For instance, if a buffer queue status is accumulated, the present disclosure can determine a headroom and a new scale value. The present disclosure can also calculate the new maximum CPU frequency by multiplying the new scale value by the current maximum CPU frequency. As such, the maximum CPU frequency may be downscaled if the buffer is accumulated. Also, if the buffer queue status is not accumulated, and the headroom is decreasing, the present disclosure can upscale the minimum CPU frequency, e.g., if the new scale value is greater than 1. Thus, the present disclosure can decrease the average frame response latency, save power, and reduce janks at the same performance level to provide to the end user better experience.

摘要： The present disclosure relates to methods and apparatus for frame processing. The apparatus can determine a current frame offset duration when a current frame rendering completion time is after a first VSYNC time. In some aspects, the current frame offset duration can be equal to a difference between the first VSYNC time and the current frame rendering completion time. The apparatus can also determine whether a sum of a previous frame GPU execution duration and the current frame offset duration is less than or equal to a first VSYNC period. In some aspects, the first VSYNC period can begin at the first VSYNC time and ends at a second VSYNC time. Additionally, the apparatus can execute a current frame based on the determination of whether the sum of the previous frame GPU execution duration and the current frame offset duration is less than or equal to the first VSYNC period.

摘要： Methods and apparatuses for providing a solution for incompatibility between nonsinusoidal waveform uninterruptible power supply (UPS) systems and active power factor correction (PFC) loads are disclosed. An embodiment of the invention includes generating a nonsinusoidal signal waveform (e.g., a voltage waveform), to be delivered to the load, with a pulse width modulation (PWM) duty width, sampling the nonsinusoidal signal waveform to collect output signal samples, and adjusting the duty width to control the nonsinusoidal signal waveform as a function of the output signal samples to deliver a desired signal characteristic (e.g., RMS signal level) to the load. In embodiments of the invention, the output duty width is adjusted differently in cases of rising and falling power consumption, respectively, by the load. Techniques disclosed herein find broad applicability in UPS systems and inverters and improve efficiency and reliability for end users and utility providers.

摘要： The present disclosure relates to methods and apparatus for frame processing. The apparatus can detect a scrolling velocity of a scrolling process associated with one or more layers in a first frame of a plurality of frames in a display, the first frame associated with a first vertical synchronization (Vsync) time. The apparatus can also determine a second Vsync time associated with a second frame of the plurality of frames in the display, the second Vsync time occurring after the first Vsync time. Also, the apparatus can calculate a position of the second frame based on the second Vsync time and the scrolling velocity. The apparatus can also render the second frame based on the position of the second frame. The apparatus can also determine whether a fling animation portion of the scrolling process has started, the fling animation portion corresponding to a user not contacting the display.
