Differential Energy Analysis for Improved Performance/Watt in Mobile GPU

Mobile devices demand high performance in a very constrained environment. As a leader in perf/watt, Qualcomm® Adreno™ GPUs, a product of Qualcomm Technologies, Inc., leverages many effective methods to improve power efficiency. In this regard, Qualcomm has developed a differential energy analysis methodology based on Ansys PowerArtist to identify the power optimization opportunity in GPU. This methodology can help to locate the inefficient part that needs further optimization in the pre-silicon stage. Experimental results based on identifying unnecessary register toggles demonstrate the effectiveness of this proposed methodology. View this on-demand webinar to learn more.
