Abstract

A device includes a non-volatile memory configured to store software to facilitate normal functions of the device, a first processing section including a data processor configured to execute the software when the device is in a normal mode, and load the software into a working memory in response to a trigger, and a second processing section coupled to a clock for maintaining a time, the second processing section configured to handle background processes when the device is in a low-power mode and initiate the trigger in response to the time of the clock preceding a user-set time by a preset advance interval, the pre-set advance interval taking into account a length of time to load the software into the working memory, wherein the working memory includes a volatile memory configured to store the software, and wherein in the low-power mode, the volatile memory receives insufficient power to store the software.

Claims

1. A battery powered device comprising:

a non-volatile memory configured to store software to facilitate normal functions of the device;

a first processing section comprising a data processor configured to execute the software when the device is in a normal mode, and load the software into a working memory in response to a trigger; and

a second processing section coupled to a clock for maintaining a time, the second processing section configured to handle background processes when the device is in a low-power mode and initiate the trigger in response to the time of the clock preceding a user-set time by a preset advance interval, the pre-set advance interval taking into account a length of time to load the software into the working memory, wherein the working memory comprises a volatile memory configured to store the software, and wherein in the low-power mode the volatile memory receives insufficient power to store the software.

2. The device of claim 1, wherein the preset advance interval is such as to enable the software to be loaded prior to the user-set time.

3. The device of claim 1, wherein the software is at least part of an operating system of the device.

4. The device of claim 1, wherein in the low-power mode the first processing section receives insufficient power to operate normally.

5. The device of claim 1, wherein the device is a portable device.

6. The device of claim 1, comprising a communication subsystem configured to communicate with a network.

7. The device of claim 6, wherein the communication subsystem comprises a communication interface configured to download external content data and a data store configured to store a list of the one or more user-set addresses, and wherein the device is configured to, in response to triggering by the second processing section, download the external content data from the one or more user-set data addresses via the communication interface.

8. The device of claim 7, wherein the preset advance interval enables the external content data to be downloaded prior to the user-set time.

9. The device of claim 7, wherein the communication interface is configured to receive the data by a wireless data link thereto.

10. The device of claim 9, wherein the communication interface is configured to receive the data by radio.

11. The device of claim 10, wherein the device is a mobile phone and the communication interface is configured to communicate with a mobile phone network for downloading the data.

12. The device of claim 7, comprising a memory for storing the downloaded data.

13. The device of claim 1, comprising a user interface for presenting the downloaded data to a user.

14. A method to operate a device comprising a non-volatile memory configured to store software to facilitate normal functions of the device, a first processing section comprising a data processor configured to execute the software, the device being configured to operate the first processing section in a normal mode in which it can execute the software and a low-power mode, wherein the device comprises a volatile memory configured to store the software when it has been loaded and wherein in the low-power mode the volatile memory receives insufficient power to store software;

and a second processing section having a clock for maintaining a time, and being configured to trigger behavior of the device in response to the time of the clock preceding a user-set time by a pre-set advance interval, the pre-set advance interval taking into account a length of time to load the software into the volatile memory;

the method comprising;

in response to triggering by the second processing section when the first processing section is in the low-power mode, directing the first processing section to load the software into the volatile memory before entering the normal mode.

15. A method comprising:

using a non-volatile memory of a device to store software to facilitate normal functions of the device;

executing the software when the device is in a normal mode, and loading the software into a working memory in response to a trigger;

processing background processes when the device is in a low-power mode; and

initiating the trigger in response to a time of a clock preceding a user-set time by a pre-set advance interval, the pre-set advance interval taking into account a length of time to load the software into the working memory, wherein the working memory comprises a volatile memory configured to store the software, and wherein in the low-power mode the volatile memory receives insufficient power to store the software.

16. The method according to claim 15, comprising setting the pre-set advance interval to enable the software to be loaded prior to the user-set time.

17. The method of claim 15, wherein the processing of background processes occurs while a data processor performing the processing receives insufficient power for normal operation.

18. The method of claim 15, comprising downloading external content data using a communication subsystem of the device.

19. The method of claim 18, wherein downloading the external content data comprises downloading the external content data from one or more user-set addresses in response to the trigger.

20. The method as recited in claim 19, comprising setting the pre-set advance interval to enable the external content data to be downloaded prior to the user-set time.
