ABSTRACT:
A method includes applying a voltage to a first processor core of a plurality of processor cores to deactivate the first processor core, the voltage less than a retention voltage of the first processor core. The application of the voltage can be in response to a software setting. The software setting can be configured via a user input, a software application, an operating system, or a BIOS setting. Alternately, the application of the voltage can be in response to a permanent hardware setting, such as the state of a fuse associated with the first processor core.
