Chen, Shih-Arn Hwang MediaTek, Hsinchu, Taiwan A high-speed and power-efficient heterogeneous octa-core CPU complex is realized in a 7nm FinFET process. On-chip sensors that handle guard band in terms of process (VPGB), voltage, temperature (VTGB), and aging (VAGB) are designed for power enhancement in dynamic frequency and voltage scaling (DVFS). A process sensor (Psensor) is used to determine per-die VPGB for Smartphone operation voltage (Vsov) with machine learning (ML). A temperature sensor (T-sensor) senses run-time local thermal and temperature inversion (T-inversion) to scale VTGB in DVFS. An aging sensor (Asensor) converts cell degradation to corresponding VAGB for aging compensation. Lastly, a voltage sensor (V-sensor) sustains system stability against supply noise. With sensor
