Abstract
Technical scheme includes a kind of MiniGUI based on linux system and draws the method shown simultaneously with GPU draftings, it is characterised in that this method includes：Call MiniGUI to draw interface and the object content for needing to draw is plotted to the first frame buffer region, after completing, the object content of drafting is sent to the first buffer zone；The object content for needing to draw is plotted to the second frame buffer region using GPU, after completing, the object content of drafting is sent to the second buffer zone；After GPU completes, the view data to the first buffer zone and the second buffer zone carries out image blend operation, and the final image data that married operation is generated are deposited in into display caching；Final image data are received and shown using the display engine of display device.Beneficial effects of the present invention are：The Image Rendering of complexity can be made of GPU while MiniGUI does interactive interface and is shown simultaneously.
Description
Technical field
Drawn the present invention relates to a kind of MiniGUI based on linux system and draw the method shown simultaneously with GPU, belonged to
Computer realm.
Background technology
MiniGUI（Built-in graphical interface supports system）It can be provided as the component of linux system for Related product
Simple interactive interface, but GPU is not supported（Graphics processor）Accelerate, thus it is common to use the product that MiniGUI is interacted
GPU can not be used to draw display.Currently, with the fast development of computer vision, GPU is more and more used in a variety of productions
On product, in order to provide a kind of interactive interface of lightweight (reduction product cost) and GPU drafting function (increase product can be used
Function), it is necessary to MiniGUI and GPU are carried out into close fit on linux system, be finally reached MiniGUI draftings content and
The effect that the content that GPU is drawn is shown simultaneously.
The content of the invention
In view of the shortcomings of the prior art, technical scheme provides kind of the MiniGUI based on linux system and drawn
The method shown simultaneously is drawn with GPU, supports GPU to draw in the scheme using MiniGUI for realizing, and by MiniGUI
The content that the content and GPU of drafting are drawn is shown simultaneously.
Technical scheme includes a kind of MiniGUI based on linux system and draws what is shown simultaneously with GPU draftings
Method, it is characterised in that this method includes：A. call MiniGUI to draw interface to be plotted to the object content for needing to draw pair
Answer the buffer zone 1 of frame buffer 1；B., the object content for needing to draw is plotted to the buffer zone of correspondence frame buffer 2 using GPU
2；C. after GPU completes, the view data to the first buffer zone and the second buffer zone carries out image blend operation, will
The final image data of married operation generation deposit in display caching；D. using the display engine of display device to final image number
According to being received and shown.
Drawn according to the MiniGUI based on linux system and draw the method shown simultaneously, described step with GPU
Rapid A also includes：Wherein the first buffer zone is a buffer area consistent with display device resolution ratio.
Drawn according to the MiniGUI based on linux system and draw the method shown simultaneously, described step with GPU
Rapid B also includes：Wherein the and (two) buffer zone is two buffer areas consistent with display device resolution ratio.
Drawn according to the MiniGUI based on linux system and draw the method shown simultaneously, described step with GPU
Rapid C also includes：Wherein married operation can be completed by the hardware figure layer of display device, by self-defined one can also be set to mix
Closing processing module is used to perform mixed processing.
Beneficial effects of the present invention are：The Image Rendering of complexity can be made of GPU while MiniGUI does interactive interface
And show simultaneously.
Brief description of the drawings
Fig. 1 show the overview flow chart according to embodiment of the present invention.
Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.A kind of MiniGUI based on linux system of the present invention is drawn draws what is shown simultaneously with GPU
Method is applied to the product for interactive interface, such as the field such as communication, medical treatment, industry control, electronics, set top box, vehicle-mounted, multimedia
Product.
Fig. 1 show the overview flow chart according to embodiment of the present invention.Shown in its is specific as follows：
（1）The content for needing to draw is plotted to fb0 by MiniGUI drafting interface（First frame buffer region）, correspond to continuous
Buffer0, buffer0（First buffer area）It is one piece and display screen resolution size identical buffer.
（2）GPU is plotted to fb1 by content is drawn（Second frame buffer region）, correspond to continuous buffer1（Second caching
Area）, buffer1 constitutes by two pieces with display screen resolution size identical buffer.
（3）When GPU, which completes, needs display, alpha blending can be passed through（Married operation）Will
Buffer0 and buffer1 carries out married operation, and the result of mixing is stored in display buffer（Display caching）In, it is used for
LCD is given to show.
（4）Alpha blending can be realized by software, can also be completed by hardware module, general to use display
The hardware figure layer alpha blending of module are completed, to ensure blending efficiency.
MiniGUI：Built-in graphical interface supports system.
GPU：Graphics Processing Unit, graphics processor.
Buffer：Memory cache.
Fb：Framebuffer：Frame buffer, for caching the data of display.Device drives on linux system.
Alpha blending：Alpha married operations, a kind of image processing techniques.
MiniGUI can also be replaced with GPU by technical scheme, and Image Rendering is completely taken over by GPU.
Technical scheme can also be realized MiniGUI drafting by GPU, and Image Rendering is completely taken over by GPU.
It is described above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as
It reaches the technique effect of the present invention with identical means, should all belong to protection scope of the present invention.In the protection model of the present invention
Its technical scheme and/or embodiment can have a variety of modifications and variations in enclosing.
