Abstract: An apparatus includes a first circuit and a second circuit sharing an instruction stream. A voltage controller circuit is configured to provide an operation voltage and at least one low-power voltage to the second circuit independent of a supply voltage of the first circuit in response to a sequence of the instruction stream. In another aspect, a method of operating a power management function is presented. The method includes providing an instruction stream for a first circuit and a second circuit and providing selectively an operation voltage and at least one low-power voltage to the second circuit independent of a supply voltage of the first circuit in response to a sequence of the instruction stream.

Abstract: An apparatus is provided. The apparatus includes a plurality of cores and a temperature sensor configured to monitor a temperature for the cores. The apparatus further includes t least one switch, each being configured to supply power to one of the cores. A thermal mitigation module is configured to operate the at least one switch at a duty cycle based on the monitored temperature. A method for thermal mitigation for an apparatus is provided. The method includes monitoring a temperature for a plurality of cores, supplying power to one of the cores at a duty cycle, and adjusting the duty cycle based on the monitored temperature. Another apparatus is provided. The apparatus includes a plurality of cores, means for monitoring a temperature for the cores, means for supplying power to one of the cores at a duty cycle, and means for adjusting the duty cycle based on the monitored temperature.
