Abstract: An apparatus includes a control circuit, configured to transition a plurality of power domains into selected performance states, and a set of state request registers. A state request register may include fields that are associated with respective power domains. The apparatus may further include circuit blocks configured to store respective state request values into respective state request registers. A given state request value may indicate a requested performance state for at least one of the power domains. In addition, a performance management circuit may be configured to select, using the associated fields in the registers, a particular performance state for at least one of the power domains. The performance management circuit may be further configured to determine a transition path to sequence to the selected performance state, and to cause the control circuit to transition to the selected performance state using the transition path.

Abstract: Various techniques and circuit implementations for power reduction management in integrated circuits are disclosed. Trigger logic circuits and rate control circuits may be implemented in combination with a power management circuit to control power provided to components of the integrated circuits. Power may be controlled based on receiving trigger signals from a power management unit. The power management circuit may implement power budgets for various components in the integrated circuits.
