Abstract

A memory management for a data processing system is provided. According to one embodiment, a method for managing memory in a telephony device is provided. The method comprising providing a known time, providing an allocator having a time-to-release parameter, allocating memory via a call to the allocator, assigning a timer having a release time and associating the timer with the memory. The time-to-release indicating the release time, which is greater than the known time.

Claims

1. A method for managing memory in a telephony device, comprising:

providing a known time;

providing an allocator having a time-to-release parameter, the time-to-release indicating a release time greater than the known time;

allocating memory via a call to the allocator;

assigning a timer having the release time; and

associating the timer with the memory.

2. The method according to claim 1, wherein associating the timer with the memory comprises:

providing a timer reference in the memory, and

providing a memory reference in the timer.

3. The method according to claim 2, further comprising expiring of the timer after a release time.

4. The method according to claim 3, further comprising:

releasing the memory, and

unassigning the timer.

5. The method according to claim 3, further comprising:

providing a secondary timer, and

adding a timer reference that references the timer to a list,

when the secondary timer expires,

releasing the timer and the associated memory for each timer reference in the list.

6. The method according to claim 3, further comprising:

providing a secondary timer, and

adding a memory reference that references the memory to a list,

when the secondary timer expires,

releasing the memory and the associated timer for each memory reference in the list.

7. The method according to claim 1, wherein the release time is appreciatively greater than the known time or wherein the release time is substantially greater than the known time.

8. A device for memory management in a real-time system, comprising:

an application having an allocator with a time-to-expire parameter;

a first memory unit for storing a memory allocated via the allocator; and

a second memory for storing a timer, the allocated memory and timer having an association, the timer having a release time in accordance to the time-to-expire parameter.

9. The device according to claim 8, further comprising a processor.

10. The device according to claim 8, wherein the release time is greater than a known time.

11. The device according to claim 10, wherein the release time is appreciatively greater than a known time or wherein the release time is substantially greater than the known time.

12. The device as according to claim 8, wherein the device is an Application-Specific Integrated Circuit (ASIC) or a Field-Programmable Gate Array (FPGA).

13. The device as according to claim 8, wherein the first and second memory units are the same memory unit.

14. The device as according to claim 8, wherein when the timer expires, the associated memory and the timer are released or wherein the application further includes a list and a secondary timer and when the timer expires a reference is stored in the list.

15. The device as according to claim 14, wherein when the secondary timer expires, the memory associated to the reference is released.

16. A system for memory management, comprising:

an application having an allocator with a time-to-expire parameter;

a processor for executing the application;

a first memory unit for storing a memory allocated via the allocator; and

a second memory for storing a timer, the allocated memory and timer having an association, the timer having a release time in accordance to the time-to-expire parameter.

17. The system according to claim 16, wherein the release time is greater than a known time.

18. The system as according to claim 16, wherein the first and second memory units are the same memory unit.

19. The system as according to claim 16, wherein when the timer expires, the associated memory and the timer are released or wherein the application further includes a list and a secondary timer and when the timer expires a reference is stored in the list.

20. The system as according to claim 19, wherein when the secondary timer expires, the memory associated to the reference is released.
