Demand paging method for mobile terminal, controller and mobile terminal

Abstract

A demand paging method for a mobile terminal, a controller and a mobile terminal, wherein the demand paging method determines, when a mobile terminal in operation needs to compress a file, a storage location of the compressed file in an external part of the controller of the mobile terminal; a decoding unit of the internal part of the controller of the mobile terminal decompresses the compressed file in the storage location; the mobile terminal saves the decompressed file to a designated part of the memory, wherein the designated part of the memory comprises the memory in the internal part of the controller of the mobile terminal and / or the memory in the external part of the controller of the mobile terminal; the mobile terminal continues to operate on the basis of the decompressed file. The technical solution increases file decompression of the mobile terminal, takes advantage of storage resources of the memory of the internal part of the controller of the mobile terminal, and saves decompressed files in the internal part of the controller, increasing the processing efficiency of demand paging of the mobile terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a request paging scheduling method in a mobile terminal, a controller and a mobile terminal. Background technique [0002] With the popularity of mobile terminals, in order to provide users with more services, the number of application programs on mobile terminals is also increasing. In addition, users often run multiple application programs at the same time when using mobile terminals, thereby increasing the memory of mobile terminals. The burden of processing instructions and data. [0003] Currently, a virtual storage mechanism is used on a mobile terminal to increase the visible size of a main memory (Main Memory) or a random access memory (Random Access Memory, RAM) of the main memory. That is, RAM is backed up by using a storage area called auxiliary storage or secondary storage on non-volatile storage devices such as hard disks, USB, and Flash (flash me...

AI Technical Summary

Problems solved by technology

[0007] According to the above-mentioned processing procedure of the mobile terminal running program, since the decompression rate of the decoding program outside the controller 10 is generally slow, and the file decompressed by the decoding program is not stored in the internal memory of the controller , thus causing a waste of internal memory resources, and also reducing the speed at which the central processing unit runs the decompressed file

[0008] For more methods of request paging, please refer to the US patent application document with publication number US7617381B2: Demand paging apparatus and method for embedded system (Demand paging apparatus and method for embedded system), but it also does not solve the above problems
