Description
Technical field
The invention belongs to technical field of image processing, specifically, being related to a kind of X-Y scheme based on GCN framework video cards
Accelerated method.
Background technology
GCN (Graphics Core Next) is a series of microarchitectures of Advanced Micro Devices exploitation and the generation of instruction set
Number.First product of GCN frameworks was released in 2011, and five iteration have been carried out in AMD GCN frameworks series so far.
Before R600 framework video cards, there is dedicated region copy acceleration hardware unit in AMD/ATI video cards, driver can be controlled directly

Switch contexts process that must be back and forth could be completed, and also therefore bring great consumption to system entirety resource, lead to GCN framves
The two dimension of structure video card accelerates operating characteristics low.
And the two dimension in existing EXA accelerated modes accelerates operating method mainly for non-GCN frameworks video card hardware characteristic
And realize, mainly comprising three parts：The initialization of 3 d rendering engine, the configuration of coloration program, the configuration of graphic resource
(vertex resource, texture resource, constant resource).This realization method does not need to toggle context process, with Glamor plus
Fast mode is compared, can be less to the consumption of system entirety resource, and performance can higher.It is reported that there are no in GCN framework video cards
The two-dimentional accelerated method of EXA accelerated modes is realized.

Carry out acceleration operation；
The code of vertex shader, which is mainly responsible for, completes vertex, texture coordinate, the translation of vector, scaling and rotation process,
The code of fragment shader is then mainly responsible for be chained up forming pixel by vertex, completes the rasterisation and pixel of 3-D graphic
The operations such as illumination, texture mapping.
S305, parameter when running is set for the binary executable in video memory；
Accelerating interface is called to realize the resource descriptor module in layer for the binary executable setting fortune in video memory
Parameter during row, parameter during these operations mainly include filling region in S301 to angular coordinate and need the color filled and
The memory address of filling region, the point coordinates and memory address in source copy region, the point coordinates in purpose copy region, foreground image
Point coordinates and memory address, cover the point coordinates and memory address of image, the point coordinates of background image, foreground image and coverage
The coordinate conversion matrix of image.
S306, start 3 d rendering engine, perform two dimension and accelerate operation；
Render instruction is sent, according to the runtime parameter set in S305, video card performs vertex shader binary system can
File and fragment shader binary executable are performed, starts 3 d rendering engine, two dimension is performed and accelerates operation.
S307, synchronic command is sent, it is ensured that operation is accelerated to complete.
GCN (Graphics Core Next) is that AMD is developed, for replacing the one of TeraScale micro-architectures/instruction set
The code name of serial microarchitecture and instruction set.GCN frameworks are also used for the visuals of AMD acceleration processing units (APU), than
In the APU used such as PlayStation 4 and Xbox One.GCN frameworks change the VLIW that AMD has adhered to always since R600
Packing is handled up pattern.VLIW (very long instruction word) is that the instruction of many items connects together, and builds up a long instruction, allows GPU's
Arithmetic element can be continuously performed with one-shot, eliminate many dispatch commands, latent period, single so as to promote operation efficiency
It is very high that thread performs density.Compared with video card before, the hardware shader core of GCN frameworks redesigns completely, and use is non-
The imperative statement collection framework of VLIW, from memory rather than all resource descriptors of register read.
EXA：A kind of figure under X window system accelerates frame, from KAA (the KDriveAcceleration
Architecture it) transplants.EXA is general acceleration frame, is used by a variety of DDX graphics drivers.
Tinter (Shader) is the short and small self defining programm that developer writes, they are the GPU in graphics card
It performs in (Graphic Processor Unit graphics processing units), instead of a part for fixed rendering pipeline, makes
Different levels are programmable in rendering pipeline.Tinter mainly includes vertex shader (Vertex Shader) and segment
Tinter (Fragment Shader) also has geometric coloration (Geometry Shader) etc. sometimes.Vertex shader master
It is responsible for completing vertex, texture coordinate, the translation of vector, scaling and rotation process.Fragment shader is mainly responsible for vertex chain
It picks up to form pixel, completes the operations such as the rasterisation of 3-D graphic and the illumination of pixel, texture mapping.In OpenGL specification
In, write tinter using GLSL (OpenGL Shading Language OpenGL shading languages).GLSL is made using C language
For basic high-order shading language, the complexity using assembler language or hardware specification language is avoided.
Area filling：It refers to being filled operation to specified rectangular area using solid color, add as basic
Speed operation, it can complete the operation of the acceleration to point, line, line segment.
Region copies：Refer to copy the pixel content of source region in destination region to.
Image blend：In computer graphics, according to the transparence information of image, by foreground image and background image according to
The bond type specified, process of the generation with part or all of transparency interaction image.Transparence information is between 0 and 1
Value is stored in image Alpha channels, is worth and is represented that pixel is transparent for 0, is worth and is represented that pixel is opaque for 1.In X Window
In system, a coverage image for only including Alpha channel informations is increased, is used to implement the rendering of polygon.
The beneficial effects of the invention are as follows：
1st, the two-dimentional accelerated method that GCN frameworks video card accelerates frame based on EXA is realized, using GCN framework video card characteristics,
