Webdie enables new opportunities for the DVFS i.e., per-core DVFS in CMPs [3,6]. In this paper, we explore the issue of run-time DVFS management of an out-of-order superscalar processor at the microarchitectural level. We provide two simple analytical models that are able to drive run-time DVFS decisions. These models allow us to predict with WebDiscussion of DVFS applies to Raspberry Pi 4 Model B, Raspberry Pi 400, and Compute Module 4 only. ... especially when using undervoltaged fixed clock peripherals (eg.
