More Information
Summary:An apparatus for masking power consumption associated with one or more operations of a logic circuitry of a processor. The apparatus comprises power-complementing circuitry configured to provide a second power consumption to directly power-complementing the power consumption associated with the one or more operations of the logic circuitry. The second power consumption complements the power consumption associated with the one or more operations of the logic circuitry. The apparatus further comprises header circuitry configured to enable a common node to vary in voltage corresponding to the one or more operations of the logic circuitry. The power-complementing circuitry and the header circuitry are each coupled to the logic circuitry at the common node.
