Abstract: A method is provided. The method includes receiving a request for a frame buffer from an application; identifying a next frame generation duration based on history information of frame timings; identifying a next frame generation start time based on a sync time corresponding to a next vertical sync (VSYNC) signal and the next frame generation duration; and providing the frame buffer to the application at the next frame generation start time

Abstract: Embodiments disclosed herein relate to device and method for processing frames. For example, a buffer of a device is arranged to store a plurality of rendered frames rendered at a frame rendering rate and a time stamp for each of rendered frames. A compositor of a device is arranged to obtain a timestamp of a synchronisation signal for synchronising the display of frames with a display refresh rate. In response to obtaining a timestamp of a synchronisation signal, a compositor is arranged to trigger access to a buffer to obtain two rendered frames having timestamps closest to a timestamp of a synchronisation signal. An interpolator of a device is arranged to generate an interpolated rendered frame for display by performing an interpolation operation using two rendered frames. An interpolation operation takes into account the difference between timestamps of each of two rendered frames and a timestamp of a synchronisation signal.
