Electronic apparatus and method for resuming from hibernation

摘要

An electronic apparatus and a method for resuming from hibernation are disclosed. The electronic apparatus comprises an external storage, a main memory, an image generating circuit and a page moving circuit. The image generating circuit writes pages from the main memory into the external storage to generate a hibernation image file during a hibernation process. The page moving circuit according to the hibernation image file sequentially writes the pages from the external storage back to a continuous page range of the main memory during a resume process. The resume process is later than the hibernation process.

主权项

1. A method for resuming from hibernation, comprising:
during a hibernation process, writing, one-by-one, a plurality of pages from a main memory to an external storage to generate a hibernation image file, and a first page table associated with said pages is further updated to a second page table, wherein the first page table records the nonconsecutive positions of the pages in the main memory, and the second table records the positions of the continuous page range of the pages in the main memory; and during a resume process, in a one-time transmission, writing the pages from the external storage to the continuous page range of the main memory according to a head of the hibernation image file, wherein the resume process is later than the hibernation process, and a size of the continuous page range of the main memory is the same as a size of the hibernation image file.
