Embodiment Construction

[0025] Firstly, the cloud desktop display optimization method based on the Android system of the present invention provides an overall cloud desktop display optimization for Android cloud terminals. like figure 1 and figure 2 , the cloud desktop display optimization method based on the Android system in this embodiment includes:

[0026] 1) Build the operating environment of OpenGL ES;

[0027] 2) Create a 2D texture for corresponding cloud desktop display data in OpenGL ES;

[0028] 3) Create two first pixel memory buffers in OpenGL ES;

[0029] 4) Alternately store the received cloud desktop display data through the two first pixel memory buffers, so that in the first half of each cycle, the CPU copies the latest cloud desktop data into the first first pixel memory buffer, At the same time, the GPU reads the cloud desktop data of the previous frame from the second first pixel memory buffer and draws it to the 2D texture; in the second half cycle, the CPU copies the late...

Abstract

The invention discloses a cloud desktop display optimization method and system based on an Android system. The cloud desktop display optimization method based on the Android system comprises the stepsof cloud desktop display optimization of an Android cloud terminal, wherein an OpenGL ES operation environment is built; a 2D texture is created in the OpenGL ES; two first pixel memory buffer areasare created in a GPU through OpenGL ES, the characteristic that a pixel buffer area in the GPU has asynchronous DMA rapid transmission is utilized, at the same time, a CPU writes cloud desktop to-be-displayed data into one pixel buffer area and immediately returns the cloud desktop to-be-displayed data, and the GPU uses data of the other pixel buffer area for texture drawing, submitting and displaying; and the two pixel buffer areas continuously and alternately serve as roles to continuously refresh the cloud desktop. According to the method and ssytem, the GPU computing power of the mobile terminal can be fully utilized under the condition that the picture quality is not reduced, so that the display of the cloud desktop becomes smooth.

Description

technical field [0001] The invention relates to an Android cloud terminal virtual machine desktop display optimization technology, in particular to an Android system-based cloud desktop display optimization method and system. Background technique [0002] Due to the rapid development of Internet infrastructure, cloud desktops are becoming more and more popular. Running cloud desktop clients on mobile terminals (Android) allows people to access services in the cloud desktop system anytime, anywhere on mobile phones and PADs. When dragging the webpage progress bar in the cloud desktop or playing a video on the Android cloud terminal, there is a freeze phenomenon. For this scenario where virtual machines transmit data into streams, conventional solutions such as reducing the resolution of the cloud desktop and reducing the number of image bits improve the smoothness of the screen, but also reduce the quality of the screen to a certain extent and affect the user experience. Co...
