Embodiment Construction

[0041] The combined memory management method and system proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0042] Please refer to figure 2 , which is a sequence diagram of the synthetic memory management method and system of the embodiment of the present invention. The present invention provides a kind of synthesis memory management method, is applied to Android platform, specifically comprises the following steps:

[0043] S100: Add a first interface to the EGL. In this embodiment, the first interface is named as the eglSwapBuffersVIV interface. Its funct...

Abstract

The invention provides a synthesis memory management method and system applied to an Android platform. The method comprises the steps of adding an eglSwapBuffersVIV interface into an EGL; during 2D synthesis in a SurfaceFlinger, calling the eglSwapBuffersVIV interface; and during 3D synthesis in the SurfaceFlinger, calling an eglSwapBuffers interface. According to the method and system, different interfaces are called when different syntheses are carried out, so that the image disordering problem during back-and-forth switching is avoided.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a synthetic memory management method and system. Background technique [0002] In the field of smart phone terminals, it is necessary to combine the contents of multiple windows into one image according to the position, size, and stacking order of the windows, save it in the frame buffer, and send it to the LCD for display. This compositing work is usually done by GPU (graphics processor), but in order to reduce power consumption and improve battery life, a 2D chip will be added. Most of the time there is no need for 3D chip compositing, so the GPU can be rested and the 2D chip accelerator can complete the compositing work. This involves the management of the frame buffer when switching between 2D and 3D synthesis. [0003] Please refer to figure 1 , which is a synthetic sequence diagram of the Android native platform. like figure 1 As shown, SurfaceFlinger is the mana...
