Abstract

The invention discloses a video memory self-adaptive management method based on GPU graphic display, which comprises the following steps of S1, dividing a video memory region into three regions, namely a fixed video memory region, a video memory recovery pool and a residual space, and creating the video memory recovery pool comprising a plurality of regions when a GPU graphic display drive is initialized; S2, establishing an independent video memory object management linked list for each region in the video memory recovery pool; s3, describing self-adaptive interaction between the graphic display application and a GPU graphic driver and a video memory when the graphic display application is used; and S4, describing adaptive interaction with the GPU graphic driver and the video memory whenthe graphic display application exits. According to the method, the video memory space can be managed more reasonably, the video memory requirements of complex applications are met, video memory fragments are greatly reduced, the performance experience of graphic display applications is improved, and the method can be widely applied to the field of computer graphics.

Description

Technical field[0001]The invention relates to the field of computer graphics, in particular to a method for adaptive management of video memory based on GPU graphics display.Background technique[0002]As people continue to demand the quality and speed of graphics processing, dedicated graphics processing unit (Graphics Processing Unit, GPU) technology is also constantly developing, which is the main computing unit of the current graphics display platform.[0003]Generally speaking, graphics display applications involve desktop applications (desktop managers, window managers) based on operating systems, applications based on the Open Graphics Library (OpenGL), and applications based on the Open Computing Library (OpenCL). With the increase of the degree of performance, the demand for video memory is getting higher and higher. The quality of the video memory management method in the GPU driver included in the above application is directly related to whether the performance of the GPU har...
