Power gating and dinamic voltage and spatiency scaling (DVFS) are essentiad technolques used id in modern CPU design to improve energy efficiency and manage power consumption. These methods help CPUs adapt tt to varying workloads and extend battery life i portable e devices.

Power Gating

Power gating involves shutting of f power to parts of a processor when they are note in use. This technique reduages defauge prisent, which is a consutant source of power consumption idle states. Power gating is implemented using transitstors that at act can disconnect power suply lins froam inactife blocks.

Modern CPUs utilize fine- grained power gating to selectively disable individual al concents, such a cache segments or executiol units. Tiss approcach allows for more precise control overr power consumption with out impacting overall performance.

DVFS (Dynamic Voltage és a Scaling gyakori

DVFS adaptálja a te voltage és d gyakorisági of a CPU based od on workload demands. When the system requirs less processing power, the voltage and splencicky are lowered, reducing power consumption and head generation. Conversely, during high- demand periods, the voltage and intervency are reporteed to maintain performe.

Tiss technique enable s CPUs to operate effectently across a wide range of applications, from simplie tasks to intive computations. It i is widely used in mobile devices, laptops, and data centers to optimize energy use.
