Graphics Energy Diagnostic Tool for Mobile Devices

Summary

Researchers at Purdue University have developed a holistic graphics energy diagnosis method and system that allows developers to systematically diagnose energy inefficiencies in app graphics operations at the app source-code level. This technology precisely profiles the energy drain of all layers of the graphics-rendering stack due to graphics operations issued at the app source code. Such profiling information of app graphics energy drain can automatically identify energy hotspots and potential energy bugs in the app source code to the app developers, who can change the code to reduce the app energy drain.
