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 at least one upcoming frame, selectively enabling additional monitoring of performed tasks by the wireless device responsive to additional processing time being available during the at least one upcoming frame and selectively disabling monitoring of performed tasks by the wireless device responsive to reduced processing time being available during the upcoming frame.

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 monitoring of performed tasks is scheduled at certain points in the at least one upcoming frame, and the selectively enabling and disabling comprises selecting enabling and disabling information in a register that is adapted to control whether monitoring occurs at different times in the at least one upcoming frame.

4. The method of claim 1, wherein the monitoring of performed tasks comprises logging 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 disabling monitoring of performed tasks is performed in response to less processing time being available during the at least one upcoming frame than a previous frame.

7. The method of claim 1, further comprising:

determining the available processing time during the at least one upcoming frame based on whether the at least one upcoming frame is 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 at least one upcoming frame based on whether the wireless device receives a speech call during the at least one upcoming frame.

9. The method of claim 1, further comprising:

determining the available processing time during the at least one upcoming frame 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:

monitoring of performed tasks is in response to more processing time being available during the at least one upcoming frame than a previous frame.

11. The method of claim 1, wherein the at least one upcoming frame 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 of said data and monitoring of performed tasks by the processor based on a processing time available to the processor to execute said at least one task during at least one upcoming frame wherein responsive to additional processor time being available selectively increasing logging of said data and monitoring of performed tasks and responsive to decreased processor time being available selectively reducing logging of said data and monitoring of performed tasks.

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 monitoring information stored by the controller and retrieved by the processor.

17. The wireless device of claim 12, wherein the processor comprises a monitoring control register accessible by the controller to selectively enable and disable the monitoring of performed tasks 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 at least one upcoming frame in response to a determination of less processing time being available during the least one upcoming frame than a previous frame.

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 at least one upcoming frame than a previous frame.

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 at least one upcoming frame is 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 at least one upcoming frame 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 at least one upcoming frame.

23. The wireless device of claim 12, wherein the controller is adapted to determine the available processing time of the processor during the at least one upcoming frame 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 at least one upcoming frame comprises at least one GSM radio frame.

25. A computer-readable storage medium tangibly embodying a program of instructions executable by a machine wherein said program of instruction comprises a plurality of program codes for controlling a wireless device, said program of instruction comprising:

one of said program codes for selectively enabling additional monitoring of performed tasks by the wireless device responsive to additional processing time being available during at least one upcoming frame and selectively disabling monitoring of performed tasks by the wireless device responsive to reduced processing time being available to the wireless device during the at least one upcoming frame.

26. The computer-readable storage medium of claim 25, wherein the monitoring of performed tasks comprises logging multiple tasks performed by the wireless device.

27. The computer-readable storage medium of claim 26, wherein the multiple tasks comprise at least one of the following:

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