Abstract
Power may be controlled for a multi-core processor that includes a processor having a first core and a second core. A first power conversion unit independently supplies a supply voltage to the first core, and a second power conversion unit independently supplies a supply voltage to the second core. The first core can be configured to supply a voltage identification signal for the first power conversion unit, and the second core can be configured to supply a voltage identification signal for the second power conversion unit that is different from the voltage identification signal for the first core.
