+Регулятор масштабирования ЦП определяет, как регулируется частота ЦП в зависимости от рабочей нагрузки, с целью либо экономии энергии, либо повышения производительности. Изменяя частоту в большую или меньшую сторону, операционная система может оптимизировать использование ЦП и, по возможности, экономить энергию. Типичные регуляторы масштабирования
