И так как основное время выполнения уходит на реальную работу (а не ожидание), а работу в компьютере выполняет <abbr title="Central Processing Unit - Центральный процессор">CPU</abbr>, такие задачи называют «ограниченными процессором» (CPU bound).

Типичные примеры CPU-bound операций — те, которые требуют сложной математической обработки.

Например:

	VSETIVLI $31, E32, M1, TA, MA, X12		// 57f60fcd
	VSETVL	X10, X11, X12				// 57f6a580
