Abstract

A technique includes based on a processing time that is available to a wireless device during an upcoming time interval, selectively enabling and disabling logging by the wireless device.

Claims

1. A method comprising:

based on a processing time available to a wireless device during an upcoming time interval, selectively enabling and disabling logging by the wireless device.

2. The method of claim 1, further comprising:

using time domain isolation in the wireless device, the time domain isolation affecting the available processing time.

3. The method of claim 1, wherein the logging is scheduled at certain points in the time interval, and the selectively enabling and disabling comprises selecting enabling and disabling information in a register that is adapted to control whether logging occurs at different times in the time interval.

4. The method of claim 1, wherein the logging comprises logging from multiple tasks performed by the wireless device.

5. The method of claim 4, wherein the tasks comprise at least one of the following:

an audio uplink task, an audio downlink task and an equalization task.

6. The method of claim 1, wherein the act of selectively enabling and disabling comprises reducing time in which logging is performed in response to less processing time being available during the upcoming time interval than a previous time interval.

7. The method of claim 1, further comprising:

determining the available processing time during the upcoming time interval based on whether the upcoming time interval contains an idle frame in which the wireless device receives one of an FCCH burst and a synchronized burst.

8. The method of claim 1, further comprising:

determining the available processing time during the upcoming time interval based on whether the wireless device receives a speech call during the upcoming time interval.

9. The method of claim 1, further comprising:

determining the available processing time during the upcoming time interval based on whether the upcoming time interval based on whether a speech input buffer of the wireless device is substantially full.

10. The method of claim 1, wherein the act of selectively enabling and disabling the logging comprises:

increasing a logging time in response to more processing time being available during the upcoming time interval than a previous time interval.

11. The method of claim 1, wherein the upcoming time interval comprises at least one GSM radio frame.

12. A wireless device, comprising:

a processor to execute at least one task and log data during execution of said at least one task;

a controller to selectively enable and disable the logging by the processor based on a processing time available to the processor to execute said at least one task during an upcoming time interval.

13. The wireless device of claim 12, further comprising:

using time domain isolation in the wireless device, the time domain isolation affecting the available processing time.

14. The wireless device of claim 12, wherein the processor comprises a digital signal processor.

15. The wireless device of claim 14, wherein the controller comprises a processor separate from the digital signal processor.

16. The wireless device of claim 12, further comprising:

a memory shared by the processor and the controller, the memory containing logging information stored by the controller and retrieved by the processor.

17. The wireless device of claim 12, wherein the processor comprises a logging control register accessible by the controller to selectively enable and disable the logging by the processor.

18. The wireless device of claim 12, wherein said at least one task comprises at least one of the following:

an audio uplink task, an audio downlink task and an equalization task.

19. The wireless device of claim 12, wherein the controller causes the first circuit to reduce the logging performed by the processor during the upcoming time interval in response to a determination of less processing time being available during the upcoming time interval than a previous time interval.

20. The wireless device of claim 12, wherein the controller is adapted to increase the logging of data by the processor in response to a determination that more processing time is available during the upcoming time interval than a previous time interval.

21. The wireless device of claim 12, wherein the controller is adapted to determine the available processing time of the processor based on whether the upcoming time interval contains an idle frame in which the wireless device receives one of an FCCH burst and a synchronization burst.

22. The wireless device of claim 12, wherein the controller is adapted to determine the available processing time of the processor during the upcoming time interval based at least in part on whether the wireless device performs additional audio or speech functions when in a general packet radio services (GPRS) call during the upcoming time interval.

23. The wireless device of claim 12, wherein the controller is adapted to determine the available processing time of the processor during the upcoming time interval based at least in part on whether a speech input buffer of the wireless device is substantially full.

24. The wireless device of claim 12, wherein the upcoming time interval comprises at least one GSM radio frame.

25. An article comprising a storage medium readable by a processor-based system storing instructions to, when executed by the processor-based system, cause the processor-based system to:

based on a processing time available to a wireless device during an upcoming time interval, selectively enabling and disabling logging by the wireless device.

26. The article of claim 25, the storage medium storing instructions to, when executed, cause the processor-based system to reduce the logging time in response to a determination that less processing is available during the upcoming time interval than a previous time interval.

27. The article of claim 25, the storage medium storing instructions to, when executed, cause the processor-based system to increase the logging time in response to more processing time being available during the upcoming time interval than a previous time interval.

28. The article of claim 25, wherein the logging comprises logging from multiple tasks performed by the wireless device.

29. The article of claim 28, wherein the multiple tasks comprise at least one of the following:

an audio uplink task, an audio downlink task and an equalization task.

30. The article of claim 25, the storage medium storing instructions to, when executed, cause the processor-based system to determine the available processing time based on at least one of the following:

whether the upcoming time interval contains an idle frame in which the wireless device receives one of an FCCH burst and a synchronization burst,

whether additional audio or speech functions are needed when in a GPRS call during the upcoming time interval, and

whether a speech input buffer in an audio codec of the wireless device is substantially full during the upcoming time interval.
