A method for operating an electronic device, and an electronic device, are provided. In the normal operation state of the electronic device, data which is stored in the main storage device of the electronic device is encrypted by a first encryption algorithm prior to being stored in a non-volatile storage device of the electronic device. The method includes the steps of generating snapshot data in the main storage device when the electronic device is entering a hibernation state, allocating space in the non-volatile storage device for storing the snapshot data, and storing the snapshot data in the space without encrypting the snapshot data using the first encryption algorithm.

A method for performing processor resource allocation in an electronic device is provided, where the method may include the steps of: obtaining task-related information to determine whether a task of a plurality of tasks is a heavy task (e.g. the heavy task may correspond to heavier loading than others of the plurality of tasks), to selectively utilize a specific processor core within a plurality of processor cores to perform the task, and determining whether at least one scenario task exists within others of the plurality of tasks, to selectively determine according to application requirements a minimum processor core count and a minimum operating frequency for performing the at least one scenario task; and performing processor resource allocation according to a power table and system loading, to perform any remaining portion of the plurality of tasks. An apparatus for performing processor resource allocation according to the above method is provided.

The present invention provides a method for managing memory space in an electronic device including: selecting a candidate page from a first memory space for swapping the candidate page out of the first memory space into the second memory space; compressing the candidate page to obtain a first compressed page and a first hash value of the first compressed page; performing a comparison using the first hash value of the first compressed page and the hash values of the pages stored in a second memory space to find whether the pages have the same content as the first compressed page or the candidate page; and if a page is found to have the same content as the first compressed page or the candidate page, mapping a virtual address of the first compressed page or the candidate page to the found page.

Electronic device and a method for managing memory space thereof

A CPU control method for controlling a first CPU and a second CPU The method comprises: (a) applying the first CPU to execute a first group of codes comprising at least one code if the first CPU is operating to perform a first function; and (c) applying the second CPU to execute a second group of codes comprising at least one code if the second CPU is operating to perform the first function. The first group of codes is optimized for the first CPU, the second group of codes is optimized for the second CPU and the first group of codes comprises at least one code different from the code for the second group of codes.
