A new research paper details a method to mitigate power bursts in mobile NPUs during inference, particularly when device batteries are low. The study, conducted on a Snapdragon 8 Gen 3 processor using MobileNetV4, found that aggressive compiler fusion can lead to concentrated execution and significant peak-current bursts. The proposed solution involves a pre-compilation graph rewrite that inserts barriers to prevent harmful superlayer merging, reducing peak current from 3.12 A to 1.94 A with minimal latency overhead.
