Abstract
Systems, methods, and computer readable media to reduce latency in a graphics processing pipeline of an electronic device having a touch-sensitive input device and a display are described herein. In one embodiment, the method includes obtaining a temporal sequence of multi-touch scan data, processing the multi-touch scan data, determining an 'optimal' time to deliver the processed multi-touch scan data to the relevant application(s) running on the device for processing, animating the resultant graphical changes that are determined by the application(s) based on the multi-touch input, and rendering the determined graphical changes to a frame buffer. In some embodiments, determining the 'optimal' time for delivering the processed multi-touch scan data to the relevant application(s) comprises measuring the performance of the relevant application(s) in order to determine how likely it is that the necessary processing of the received multi-touch information may be completed before the conclusion of the next vertical blanking interval.
