Abstract
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.
