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.
