Voltage and frequency scaling may refer to:
Voltage and frequency scaling are often used together to save power in mobile devices including cell phones. When used in this way it is commonly known as DVFS, or Dynamic Voltage and Frequency Scaling.
- Dynamic voltage scalingDynamic voltage scalingDynamic voltage scaling is a power management technique in computer architecture, where the voltage used in a component is increased or decreased, depending upon circumstances. Dynamic voltage scaling to increase voltage is known as overvolting; dynamic voltage scaling to decrease voltage is known...
