A method and device for sharing display memory

Abstract

The embodiment of the invention provides a sharing method and device for a memory for display and relates to the technical field of communication. The sharing method and device are used for increasing the memory use ratio of a multi-system mobile terminal. The sharing method for the memory for display comprises the steps that all systems of the multi-system mobile terminal generate distribution requests of application programs to be displayed respectively; the distribution requests of the application programs to be displayed are analyzed in a unified mode, and a graph buffering region is distributed to each application program to be displayed according to the analysis result, so that the application programs, to be displayed, in a foreground system are preferably distributed to the graph buffering regions; frame content data of the application programs to be displayed are stored into the distributed graph buffering regions correspondingly. The sharing method and device can be applied to the multi-system mobile terminal.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a display memory sharing method and device. Background technique [0002] The multi-system mobile terminal has a variety of operating system platforms. When using it, there is usually a foreground system interacting with the user and other standby background systems, which can perform real-time switching between the foreground system and any background system, so that users can Run corresponding software or use corresponding functions on corresponding operating systems as required. Therefore, under the premise that current mobile terminal applications are widely and massively developed, multi-system mobile terminals have good adaptability and compatibility. [0003] However, the operation of the system requires the application program to occupy a certain amount of display memory. In the above-mentioned multi-system mobile terminal, it is necessary to be able to dynamically...

Problems solved by technology

[0003] However, the operation of the system requires the application program to occupy a certain amount of display memory. In the above-mentioned multi-system mobile terminal, it is necessary to be able to dynamically switch between multiple systems in real time. In order to achieve dynamic switching between multiple systems, Even for the background system in the standby state, it is necessary to reserve display memory for all its applications, so that when the system is switched, the new foreground system can display and operate, so that each background system needs to consume with the foreground system. Roughly the same amount of display memory

However, at the same time, the user generally only interacts with the foreground system, so the display memory occupied by the background system in the standby state is not necessary for the current display, resulting in low memory utilization of the multi-system mobile terminal
