Beschreibung
Zusammenfassung:	An all-digital closed-loop fine-grained control of voltage and frequency for running conditions of a compute machine such as graphic processor unit (GPU), central processing unit (CPU), or any other processing unit. The scheme optimizes the voltage margin and frequency on the fly according to desired programmable performance metrics. A mitigation response to droops is naturally built into the system and is equal to the cause rather than being excessive. The scheme is scalable and can be instantiated in different clusters for best results.
