Abstract: Apparatuses and methods to adjust voltage for thermal mitigation are provided. The apparatus includes a circuit, a plurality of switches configured to provide power of a power domain to the circuit, a plurality of thermal sensors disposed at different locations about the circuit and configured to detect temperatures at the different locations, and a control circuit configured to determine that one of the detected temperatures at one of the locations exceeds a temperature threshold, and in response, adjust one or more of the plurality of switches in proximity with the one location to reduce power provided to the circuit. The method includes providing power of a power domain through a plurality of switches, detecting a temperature at a location exceeding a temperature threshold, and adjusting the plurality of switches in proximity with the location to reduce the power provided, in response to the detecting the temperature exceeding the temperature threshold.

Abstract: A power delivery network (PDN) including a battery, a set of regulators for generating supply voltages, and an integrated circuit (IC) including power rails configured to receive the supply voltages. The IC further includes an IC chip having a set of cores. The power rails includes a larger rail configured to provide a full range of currents, and the other smaller power rails each configured to provide lower range of currents. The IC includes multiplexers having first inputs coupled respectively to the smaller rails, second inputs coupled to the larger rail, and outputs coupled to the cores. When the smaller rail is able to supply the current needed by a core, the multiplexer is configured to couple the smaller rail to the core. When the smaller rail cannot supply the current needed by the core, the multiplexer is configured to couple the larger rail to the core.
