Method and apparatus for controlling power consumption of a portable terminal

1. A method of controlling power consumption in a terminal, the method comprising:

receiving first data from at least one device, by a main processor;

transmitting second data based on the received first data to a sub processor, by the main processor;

receiving the second data from the main processor, and determining whether the main processor is in a sleep state, by the sub processor; and

when it is determined that the main processor is in the sleep state:

maintaining the sleep state of the main processor, receiving the first data from the at least one device, controlling the at least one device based on the received first data and second data, and outputting third data, based on the first data and the second data, as data for controlling a synchronization process, by the sub processor.

2. The method of claim 1 , further comprising transmitting the third data to a communication module, by the sub processor.

3. The method of claim 2 , wherein the second data is connection information of the first data and the communication module.

4. The method of claim 1 , further comprising outputting the third data to an interface, by the sub processor.

5. The method of claim 1 , further comprising controlling the at least one device by previously setting an operation time of at least one of the main processor and the sub processor.

6. A method of controlling a power consumption in a terminal, the method comprising:

receiving first data from at least one device, by a main processor;

determining a state of the main processor;

receiving second data based on the first data from the main processor, by the sub processor, during a pre-determined time before entering a sleep state of the main processor; and

when the main processor is in the sleep state:

maintaining the sleep state of the main processor, receiving the first data from the at least one device, controlling the at least one device based on the received first data and second data, and outputting third data, based on the first data and the second data, as data for controlling a synchronization process, by the sub processor.

7. The method of claim 6 , further comprising transmitting the third data to a communication module, by the sub processor.

8. The method of claim 6 , further comprising outputting the third data to an interface, by the sub processor.

9. The method of claim 6 , further comprising controlling the at least one device by previously setting an operation time of at least one of the main processor and the sub processor.

10. An apparatus of controlling a power consumption in a terminal, the apparatus comprising:

a main processor and;

a sub processor,

wherein the main processor is configured to receive first data from at least one device, to control the at least one device based on the first data, and to transmit second data based on the first data to the sub processor, and

the sub processor is configured to receive the second data from the main processor, to determine whether the main processor is in a sleep state, and when it is determined that the main processor is in the sleep state, to maintain the sleep state of the main processor, to receives the first data from the at least one device, to control the at least one device based on the received first data and second data, and output third data, based on the first data and the second data, as data for controlling a synchronization process.

11. The apparatus of claim 10 , wherein the sub processor is configured to transmit the third data to a communication module.

12. The apparatus of claim 10 , wherein the sub processor is configured to output the third data to an interface.

13. The apparatus of claim 10 , wherein the sub processor is configured to control the at least one device by previously setting an operation.

14. The apparatus of claim 12 , wherein, when it is determined that the main processor is not in the sleep state, outputting the third data as data for a state of the at least one device.
