Abstract
A mechanism is provided for an integrated circuit with power gating. A power header switch is configured to connect and disconnect any one of multiple circuits to a common voltage source, where a powered off circuit is disconnected from the common voltage source. A power-up sequencer includes an initial stages power-up component and a final stages power-up component. The final stages power-up component is configured to execute final stages of a power-up process for the powered off circuit, and the initial stages power-up component is configured to execute initial stages of the power-up process for the powered off circuit. The initial stages power-up component is activated in response to a predictive power-up request.
