Features sophisticated master and slave arbitration to resolve bus contention, including "Round Robin" for masters and priority-based for slaves. acutena.com Key Features of SPMI v2.0
This paper examines the MIPI SPMI specification (v2.0) and its role in modern System-on-Chip (SoC) power management. It explores how SPMI's 2-wire shared bus and multi-master capabilities enable "fine-grained" dynamic voltage and frequency scaling (DVFS) far beyond what legacy interfaces like I2C could achieve. The study evaluates its efficacy in reducing PCB complexity while meeting the sub-millisecond latency requirements of 5G and AI-driven mobile workloads. 2.
