A real-time operating system runs on a processor and dynamically manages the power state of individual circuits or resources with the processor. Thus, if a particular circuit is not needed, power to that circuit can be disabled. If a circuit is shut down, any configuration information or other type of data can be saved before powering off the circuit. Power can be re-enabled to the circuit on a responsive or predictive basis and the configuration information and/or data (collectively referred to as "state" information) can be reloaded into the circuit.
