Abstract
A method and system for power management is provided. To control power supplied to a second electronic device (106), an electronic system (100) comprises a power management subsystem (110), a first electronic device (102); The power management subsystem (110) monitors the power consumed by the first electronic device (102) to control the power supplied to the second electronic device (106). A method for power management of a second electronic device (106) is provided. A power management subsystem (110) is provided.
Claims18
A power management subsystem comprising:
- a monitoring device having an input for receiving a power consumption signal, which represents power consumption of a first electronic device which performs a task resulting in an output;
- and
- a power controller;
- wherein the monitoring device is operative to process the power consumption signal to generate a power control signal;
- and
- wherein the power controller is operative to control power supplied to a second electronic device which performs a task resulting in an output, the power supplied to the second electronic device being dependent on the power control signal;
- further including a comparator connected to the first and second electronic devices for comparing the outputs of the first and second electronic devices.
A method for power management of a second electronic device which second electronic device performs a task resulting in an output, the method comprising the steps of:
- monitoring a power consumption signal, which represents power consumption of a first electronic device which performs a task resulting in an output during a first period;
- processing the power consumption signal for generating a power control signal;
- and
- controlling power supplied to the second electronic device during a second period, according to the power control signal;
- comparing the outputs of the first and second devices.
