摘要： An embedded system comprises a circuit for executing operations, a power management unit for interfacing with at least one power source, a main storage unit for storing energy from the power source for provision to the circuit, at least one inductor for accumulating energy from the power source for transfer to the main storage unit and for accumulating energy from the main storage unit for transfer to the circuit, and a sensor circuit for monitoring a current through the at least one inductor as the energy is accumulated thereon. The power management unit is configured to connect the inductor to transfer energy to the main storage unit or to the circuit in response to a signal from the sensor circuit that peak current has been reached. Also described is a device including an embedded system and a method for operating an embedded system.

摘要： Described herein is an embedded system comprising: at least one power domain comprising analogue and/or digital circuitry; at least one domain storage unit (166) for providing energy to the power domain; a main storage unit (172) for storing energy for provision to the at least one domain storage unit; power switches for controlling the flow of energy between the storage units of the circuit; and a power management unit operable to control the power switches to transfer energy from the at least one domain storage unit back to the main storage unit or to an additional domain storage unit of the system. Also described is a method for operating an embedded system.
