Dynamic Voltage Scal<strong>in</strong>g<br />
● Refers to runtime change <strong>in</strong> supply voltage levels<br />
supplied to various components <strong>in</strong> a system so as<br />
to reduce the overall system power dissapation<br />
while ma<strong>in</strong>ta<strong>in</strong><strong>in</strong>g constra<strong>in</strong>ts on time/throughput<br />
● When operation at less than peak frequency is<br />
permissible, frequency is lowered, followed by<br />
reduction <strong>in</strong> voltage<br />
● Significant power reduction as both f & V are<br />
lowered
