Adaptive Voltage Scaling (AVS) is a closed-loop dynamic power minimization technique that reduces power based on the actual operating conditions of the chip, i.e., the power consumption is continuously adjusted during the run time of the chip. Typically the design of any chip is done in such a way that it meets most demanding application throughput requirements under worst case operating conditions. This leads to an excess margin or wastage of power because the chip usually operates under typical operating conditions. AVS is beneficial compared to the conventional Dynamic voltage scaling (DVS) approach, a commonly encountered open loop dynamic power minimization technique, because AVS eliminates the excess power margins that are present in the open loop DVS systems due to the fixed voltage
