Dynamic Voltage Scaling (DVS) is a power management technique used in electronic devices to adjust the voltage and frequency according to the workload. By lowering the voltage during less demanding tasks, devices can save energy and reduce heat generation, which is crucial for battery-operated gadgets like smartphones and laptops. This method enhances the overall efficiency of processors and extends battery life without significantly impacting performance. DVS is commonly implemented in microprocessors and embedded systems, allowing them to operate at optimal levels while minimizing power consumption, which is increasingly important in today's energy-conscious environment.
