Abstract
A method for operating an electronic apparatus is provided. The method includes receiving a token, activating a power switch for powering up a core in response to the receiving the token, and outputting the token based on a state of powering up the core. The outputting of the received token is delayed until the state of powering up the core is reached. In one aspect, an electronic apparatus includes a power switch configured to power up to a core is provided. A power-switch control circuit is configured to receive a token, activate the power switch for powering up the core in response to receiving the token, output the received token based on a state of powering up the core. The outputting of the received token is delayed until the state of powering up the core is reached. A plurality of the power-switch control circuits is configured as a ring.
