Claim 18:
19. A non-transitory computer readable medium storing a plurality of instructions for a power management processor in a power management circuit of an integrated circuit that also comprises a plurality of components, wherein the integrated circuit further comprises a global power control circuit configured to apply power control across the plurality of components responsive to trigger signals to the integrated circuit, and wherein the plurality of instructions, when executed by the power management processor, cause the power management processor to perform operations comprising;
receiving, at the integrated circuit, a plurality of supply voltages from a plurality of voltage regulators, wherein a plurality of power delivery trigger circuits is coupled to the integrated circuit and the plurality of voltage regulators, wherein the plurality of power delivery trigger circuits includes a first type of power delivery trigger circuit and a second type of power delivery trigger circuit coupled to one or more sets of voltage regulators in the plurality of voltage regulators, and wherein a given set of voltage regulators is coupled to at least one power delivery trigger circuit of the first type and at least one power delivery circuit of the second type;
generating, by the first type of power delivery trigger circuits coupled to the integrated circuit by a plurality of one-way wired interfaces, trigger signals when an electrical load experienced by the voltage regulators satisfies a first threshold; and
generating, by the second type of power delivery trigger circuits coupled to the integrated circuit by a plurality of two-way serial communication interfaces, trigger signals when the electrical load experienced by the voltage regulators satisfies a second threshold, wherein the first threshold is closer to a functional failure point of the integrated circuit than the second threshold.
