Claims20
An electronic device, comprising:
- a power management device, the power management device generating a plurality of powers according to power management information;
- and
- a processor, the processor including a plurality of power blocks supplied with the plurality of powers through a plurality of power lines, and including a power consumption measurement block that measures power consumption of respective power blocks of the plurality of power blocks.
A method of measuring power consumption of an electronic device that includes a power management device generating a plurality of powers according to power management information, and including a processor having a plurality of power blocks supplied with the plurality of powers through a plurality of power lines and having a power consumption measurement block measuring power consumption of each of the plurality of power blocks, the method comprising:
- receiving test data from the outside;
- setting the power management device according to the received test data;
- measuring power consumption according to the received test data;
- storing the measured power consumption information;
- and
- outputting the stored power consumption information to the outside.
An electronic device, comprising:
- a boot memory storing a boot code;
- a main memory storing a processing program;
- a power management device supplied with power through a battery and generating a plurality of powers according to power management information;
- and
- a processor having a plurality of power blocks supplied with a plurality of powers from the power management device, and having a power consumption measurement block measuring and storing power consumption of each of the plurality of power blocks, the processor performing a boot up according to the boot code of the boot memory, and processing the stored power consumption information according to the processing program of the main memory.
An electronic device, comprising:
- a processor unit, the processor unit including a processor and having at least two power blocks;
- a power supply unit, the power supply unit providing power to the at least two power blocks;
- and
- electric current sensors respectively corresponding to the at least two power blocks, each electric current sensor monitoring power consumption of a power block, wherein:
- the processor can be placed into at least two operation modes, the operation modes including a first operation mode that is a sleep mode and second operation mode that is a normal mode, and
- the processor is configured to output information regarding the power consumption that is monitored by the electric current sensors in response to a command, the information including information regarding power consumption in the first operation mode and information regarding power consumption in the second operation mode.
