Abstract
A method for profiling energy usage in graphics user interface (UI) update in handheld mobile devices is disclosed. The method includes mapping the pixel changes of each frame to a responsible UI update, identifying method invocations at all layers of the UI rendering stack, tracking asynchronous dependence across all layers of the UI rendering stack corresponding to each UI update by assigning a unique frame identification (ID) per frame refresh to track asynchronous dependence between UI updates and corresponding callbacks across all layers of the UI rendering stack, tracking information flow across a corresponding graphics processing unit (GPU) by using an OpenGL record-and-replay method, reconstructing the frames by replaying the OpenGL calls on the GPU during post processing, comparing frames to account for pixel changes, and tracking and attributing the energy usage during UI operations to individual UI updates.
