10.2 A Dynamic Performance Augmentation in a 3nm-Plus Mobile CPU

This work presents dynamic mobile-performance augmentation (DMPA), featuring boosting-duty control (BDC) and an adaptive thermal cooler (ATC) to augment CPU maximum performance. The BDC uses an aging sensor (A-sensor) to leverage an aging budget for performance boosting. For thermal, the ATC integrates temperature sensors (T-sensors) across the CPU and works with multiple sensors and a throttler to optimize clock speed effectively cooling hotspots. The DMPA offers a score of 3917 in the GeekBenchv6 single-core benchmark on a flagship smartphone, consuming 0.078% or less total power, while occupying only 0.0122% of the CPU area.
