Adaptive voltage scaling (AVS) is a closed-loop dynamic power minimization technique that adjusts the voltage supplied to a computer chip to match the chip's power needs during operation. Many computer chips, especially those in mobile devices or Internet of things devices are constrained by the power available (for example, they are limited to the power stored in a battery) and face varying workloads.[1] In other situations a chip may be constrained by the amount of heat it is allowed to generate.
