Proactive Power Management-Based Supply Regulation with Online Learning for Variation-Tolerant Workload-Aware Droop Mitigation in 28nm CMOS
Abstract
A 28 nm SoC solution with integrated proactive power management for droop mitigation is demonstrated combining a neural droop management unit, integrated high speed power converter, and an online learning engine to combat the PDN and workload variations. The 28nm test chip integrated with CPU and accelerators achieves 59% worst-case droop reduction,$48 \times$throttling reduction, and$>91 {\%}$regulator peak efficiency, reducing performance degradation from prior fixed-model or throttling-only schemes.
