摘要： A multicore processor system utilizes a power manager for improving power consumption. The system includes multiple processing units and multiple power sources. Each power source is connected to two or more processing units. A condition for activating a processing unit is detected. In response to the detected condition, the power manager identifies a power source that is connected to inactive processing units only. The power manager then activates a target processing unit among the inactive processing units connected to the identified power source.

摘要： 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.

摘要： Methods and apparatuses pertaining to dynamic memory sharing may involve sharing a first portion of a memory associated with a first module for use by a second module. The first portion of the memory may be reclaimed for use by the first module in real time upon a determination that there is an increase in demand for the memory by the first module that requires reclamation, such that the first module begins to use the first portion of the memory before the second module finishes a process of aborting to use the first portion of the first memory.

摘要： A multicore processor system includes multiple processor cores. When a processor core goes offline, the offline processor core is mapped to a mapped processor core, which is selected from an emulated processor core and one or more online processor cores among the multiple processor cores. The emulated processor core is a software construct containing an emulated state of the offline processor core. When the multicore processor system receives a system call that is sent from a requestor to the offline processor core to request for system information from the offline processor core, the system call is re-directed to the mapped processor core. The system information is returned from the mapped processor core to the requestor in response to the system call.

摘要： An efficient, on-demand, content-based memory sharing method is performed by a system. The method begins when an event is detected. The system predicts a merge gain based on a current number of candidate pages in the memory, a current number of merged pages, and a merge ratio which represents a merged-to-candidate page ratio. In response to a determination that the merge gain is greater than a threshold, the system performs a scan and merge operation to merge a set of the candidate pages, which have a same content and have not been merged, into a single page having the same content.

摘要： 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.
