Abstract

To update machine-readable instructions in an electronic device, update information for updating the machine-readable instructions of the electronic device is determined based on reducing an update time that accounts for a communication link speed and an application time for applying the update information, where the application time is dependent upon information relating to the components of the electronic device.

Claims

1. A method of updating machine-readable instructions in an electronic device, comprising:

receiving, by a system having a processor, information relating to components of the electronic device;

receiving, by the system, communication link speed information regarding a speed of communicating data over a link to the electronic device; and

determining, by the system, update information for updating the machine-readable instructions of the electronic device, wherein determining the update information is based on reducing an update time that accounts for the communication link speed and an application time for applying the update information, wherein the application time is dependent upon the information relating to the components of the electronic device.

2. The method of claim 1, further comprising calculating the update time that includes a communication time and the application time, wherein the communication time is based on the communication link speed and a size of the update information.

3. The method of claim 2, wherein determining the update information comprises:

adjusting content of the update information based on the communication link speed and the corresponding application time.

4. The method of claim 1, wherein receiving the information relating to the components comprises receiving information relating to hardware components in the electronic device.

5. The method of claim 1, wherein receiving the information relating to the components comprises receiving information selected from among times associated with predetermined operations, an algorithm used for performing an update of the machine-readable instructions, overhead of an operating system to access data, an ability to perform multitasking, and types of system calls used during an update of the machine-readable instructions.

6. The method of claim 1, further comprising:

determining at least one task associated with updating the machine-readable instructions that can be performed as a background process of the electronic device, wherein determining the update information for updating the machine-readable instructions is based on reducing the update time that accounts for the communication link speed, the application time, and a time associated with the background process.

7. The method of claim 1, wherein determining the update information based on reducing the update time comprises determining the update information based on minimizing the update time.

8. The method of claim 1, further comprising:

sending the update information to the electronic device to cause the update of the machine-readable instructions at the electronic device.

9. An electronic device comprising:

a processor;

a communication interface to a communication link;

machine-readable instructions executable on the processor that are updateable;

a profiler executable on the processor to collect information regarding components of the electronic device, wherein the profiler is to cause the collected information to be sent to an update system to generate update information for updating the machine-readable instructions, wherein content of the update information generated by the update system is dependent upon reducing an update time that is based on aggregating a communication time and an application time, wherein the communication time is based on a speed of the communication link, and the application time is a time for applying the update information that is based on the collected information; and

an update agent executable on the processor to receive the update information having content generated by the update system that is dependent upon reducing the update time.

10. The electronic device of claim 9, wherein the collected information comprises at least one selected from among:

information relating to features of hardware components in the electronic device, information relating to performing predetermined operations associated with updating the machine-readable instructions, and information relating to a platform of the electronic device.

11. The electronic device of claim 9, wherein the content of the update information is adjusted to reduce the application time if the communication link has a higher communication speed.

12. The electronic device of claim 11, wherein the content of the update information is adjusted to allow for avoiding at least one selected from among:

performing decompression of a portion of the update information at the electronic device, calculating a check code based on the update information, and preprocessing executable code in the update information.

13. The electronic device of claim 9, wherein the updateable machine-readable instructions include software instructions or firmware instructions.

14. The electronic device of claim 9, wherein the update agent is executable to further:

determine a time to initiate application of the update information.

15. The electronic device of claim 14, wherein determining the time to initiate application of the update information is based on a present location of the electronic device.

16. The electronic device of claim 14, wherein determining the time to initiate application of the update information is based on an analysis of usage information of the electronic device to predict a time interval during which usage of the electronic device is expected to be reduced.

17. An article comprising machine-readable storage media storing instructions that upon execution cause a system having a processor to:

receive profile information relating to components of the electronic device;

receive communication link speed information regarding a speed of communicating data over a link to the electronic device; and

determine update information for updating machine-readable instructions at the electronic device, wherein determining the update information is based on reducing an update time that accounts for the communication link speed and an application time for applying the update information, wherein the application time is estimated based on the profile information.

18. The article of claim 17, wherein a function associated with updating the machine-readable instructions at the electronic device can be performed as a background operation in the electronic device, and wherein determining the update information is based on reducing the update time that accounts for the communication link speed, the application time for applying the update information, and a time for performing the background operation.

19. The article of claim 17, wherein the profile information comprises at least one selected from among:

information relating to features of hardware components in the electronic device, information relating to performing operations associated with updating the machine-readable instructions, and information relating to a platform of the electronic device.
