Abstract

A method of updating an original version of content to a new version of content, in a non-volatile memory storage device, the method includes: providing a non-volatile content memory storage area arranged to accommodate a full version of content; providing an auxiliary memory area; performing, while at least part of the content memory storage area is not being updated, at least one pre-update operation corresponding to at least one in-place update operation applicable, in an in-place update, on the part of the content memory storage area; storing, while at least part of the content memory storage area is not being updated, at least one result of the performed at least one pre-update operation, on the auxiliary memory area; and performing an in-place update of the at least part of the content memory storage area utilizing the at least one result stored on the auxiliary memory area.

Claims

1. A method of updating an original version of content to a new version of content, in a non-volatile memory storage device, the method comprising:

providing a non-volatile content memory storage area arranged to accommodate a full version of content;

providing an auxiliary memory area;

performing, while at least part of the content memory storage area is not being updated, at least one pre-update operation corresponding to at least one in-place update operation applicable, in an in-place update, on the part of the content memory storage area;

storing, while at least part of the content memory storage area is not being updated, at least one result of the performed at least one pre-update operation, on the auxiliary memory area; and

performing an in-place update of the at least part of the content memory storage area utilizing the at least one result stored on the auxiliary memory area.

2. The method of claim 1, wherein the at least one pre-update operation comprises calculations required for the in-place update.

3. The method of claim 1, wherein the at least one pre-update operation results in content required for later copying onto the content memory storage area.

4. The method of claim 1, wherein the performing at least one pre-update operation or the storing at least one result are performed while the content memory storage area is being used.

5. The method of claim 4, wherein the performing an in-place update of the content memory storage area comprises at least one of:

copying the content stored on the auxiliary memory area onto the content memory area; and

utilizing the calculations stored on the auxiliary memory area thereby reducing in-place update time.

6. The method of claim 4, further comprising simultaneously performing an in-place update while the content memory storage area is being used;

and performing a rendering process that includes provision of requested content from the content memory storage area.

7. The method of claim 6, wherein the provision of content comprises generating the requested content utilizing at least part of the content stored on the auxiliary memory area, in case the requested content is not available on the content memory storage area.

8. A system for updating an original version of content to a new version of content, in a non-volatile memory storage device, the system comprising:

a non-volatile content memory storage area arranged to accommodate a full version of content;

an auxiliary memory area;

a pre-update module; and

an in-place update module,

wherein the pre-update module is arranged to;

perform while at least part of the content memory storage area is not being updated, at least one pre-update operation,

wherein the at least one pre-update operation corresponds with at least one in-place update operation applicable on the content memory storage area; and

store at least one result of the performed at least one pre-update operation, on the auxiliary memory area, and

wherein the in-place update module is arranged to perform an in-place update of the content memory storage area utilizing the at least one result stored on the auxiliary memory area.

9. The system of claim 8, wherein the at least one pre-update operation comprises calculations required for the in-place update.

10. The system of claim 8, wherein the at least one pre-update operation results in content required for later copying onto the content memory storage area.

11. The system of one of claims 8, wherein the pre-update module performs the at least one pre-update operation or stores at least one result of the performed at least one pre-update operation while the content memory storage area is being used.

12. The system of claim 11, wherein the in-place updating module is further arranged to at least one of:

copy the content stored on the auxiliary memory area onto the content memory area; and

utilize the calculations stored on the auxiliary memory area thereby reducing in-place update time.

13. The system of claim 11, further comprising a rendering module arranged to perform a rendering process while the in-place update occurs and while the content memory storage area is being used, wherein the rendering process comprises provision of requested content from the content memory storage area.

14. The system of claim 13, wherein the rendering module is further arranged to generate the requested content utilizing at least part of the content stored on the auxiliary memory area, in case the requested content is not available on the content memory storage area.

15. A computer program product implemented on a machine readable storage device, tangibly embodying a program of instructions executable by the machine to perform method steps for updating original content stored in a non-volatile memory associated with a device to yield updated content, the method comprising:

performing, while at least part of the content memory storage area is not being updated, at least one pre-update operation corresponding to at least one in-place update operation applicable, in an in-place update, on the part of a content memory storage area arranged to accommodate a full version of content;

storing, while at least part of the content memory storage area is not being updated, at least one result of the performed at least one pre-update operation, on an auxiliary memory area; and

performing an in-place update of the at least part of the content memory storage area utilizing the at least one result stored on the auxiliary memory area.
