"1 234 567 890"Кэш процессора Кэш микропроцессора — кэш (сверхоперативная память), используемый микропроцессором компьютера для уменьшения среднего времени доступа к компьютерной памяти. Является одним из верхних уровней иерархии памяти. Кэш использует небольшую, очень быструю память (обычно типа SRAM), которая хранит копии часто используемых данных из основной памяти.
