COMPRESSED FREEZER FILES

摘要

In one embodiment, when a secondary application on an electronic device is selected for deactivation, the memory associated with the application can be gathered, compacted and compressed into a memory freezer file. The memory freezer file can be stored in non-volatile memory with a reduced storage footprint compared to a memory stored in a conventional swap file. When the selected application is to be reactivated, the compressed memory in the memory freezer file can be quickly restored to process memory.

1. A method comprising:
gathering a first set of compressed data elements from a first region of virtual memory addresses; gathering a set of uncompressed data elements from a second region of virtual memory addresses, the first and second regions of virtual memory addresses associated with a process; compacting the first set of compressed data elements into a first set of compacted memory segments; compressing the uncompressed data elements into a second set of compressed data elements; compacting the second set of compressed data elements into a second set of compacted memory segments; and storing the first and second set of compacted memory segments to a third region of virtual memory addresses.
