Which of the following processor states does not save power?
A.
C2
B.
C1
C.
C3
D.
C0
Explanation:
The C0 processor state does not save power. It is an operational state.
Answer option B is incorrect. The C1 state is a powered down state, but the processor takes action
immediately on request. The C1 state uses less power than C0 state.
Answer option A is incorrect. The C2 state is also known as Stop-Clock. It uses less power than C1
state. In this state, the processor takes a little longer time than C1 state to come in action on the
request of applications.
Answer option C is incorrect. The C3 state is also known as the sleep mode. In this state, the
processor cache is flushed. In this state, the processor takes a few seconds to be available for action.
