Graphic processing method, graphic processing device mobile terminal

Abstract

The invention provides a graphic processing method and a graphic processing device. The graphic processing device comprises a front buffer, a back buffer and a middle buffer with internal memory smaller than the that of the front buffer / back buffer, wherein a first graph and a second graph are respectively filled in the front buffer and the back buffer, and a third graph is filled in the front buffer. A first graph non-display area is extracted to the middle buffer for once or a plurality of times so as to lead the front buffer to obtain and use spare space to form the third graph. The invention further provides a mobile terminal. Graph transformation between the front buffer and the back buffer and third graph filling are completed through once extracting or a plurality of times of extracting. The internal memory of the middle buffer is smaller than that of the front buffer / back buffer so that internal memory resources are saved, and the problem of internal memory lack is solved.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a graphics processing method, a graphics processing device and a mobile terminal. Background technique [0002] In many computer systems with advanced graphics processing capabilities, the graphics processing system includes a double buffering module. A double buffer module has two memory segments, a front buffer and a back buffer. The front buffer fill completely obtains the image rendered by the graphics processing system, and provides the image to the display driver for display on the display screen. [0003] Wherein, the back buffer is filled with images being translated by the graphics processing system. Once the translation of the back buffer is completed and the images in the front buffer are fully displayed, the graphics filled in the front and back buffers can be flipped at any time. That is, the graphics filled in the front and rear buffers are swapped. For example,...

AI Technical Summary

Problems solved by technology

[0005] The existing technology needs to create a middle buffer equal to the front buffer / back buffer to complete the filling of data. For continuous image processing operations, three memory blocks of equal size are required to complete the above graphics processing, which is relatively tight for memory. very disadvantageous for the system

In particular, for the intermediate state of page turning, such as the first page is pulled down to the second page, there will be a situation where part of the first page and part of the second page are located on the display screen, that is, part of the first page is filled in the front buffer. One page and part of the second page, the swap of the front and rear buffers only needs to swap a part of the data of the back buffer to the front buffer, in this case use the middle buffer equal to the front buffer / back buffer is a waste of resources
