Problems solved by technology

When the design is expressed as a system-level model, it is easy to use different algorithms to try the design multiple times, and it can be quickly completed by switching to different structures; if the register-transfer-level or gate-level model is used To express the design, the scale is usually quite large, and it is time-consuming, if not too difficult, to experiment with different design structures or make some changes

Embodiment Construction

[0036] The present invention will now be described in detail in conjunction with the accompanying drawings.

[0037] An embodiment of the present invention proposes a GPU command processor unit hardware TLM microstructure based on SystemC, such as figure 1 As shown, including Graph Cmd Fifo Model1, Read Graph Command Model2, OpenGLCommand Process Model3 and Command DMA Process Model4;

[0038] Graph Cmd Fifo Model1, Read Graph Command Model2, OpenGL CommandProcess Model3 and Command DMA Process Model4 are connected sequentially through transaction-level interfaces.

[0039] In one embodiment, Graph Cmd Fifo Model1 is used for receiving OpenGL command;

[0040] Read Graph Command Model2 is used to continuously read the data in Graph Cmd Fifo, and trigger the execution of OpenGL Command Process Model3 when a valid CMD command is received;

[0041] OpenGL Command Process Model 3 is used to perform different operations according to the packet header of the CMD command packet. Ju...

Description

technical field [0001] The invention relates to the technical field of computer hardware modeling, in particular to a SystemC-based GPU command processor unit hardware TLM microstructure. Background technique [0002] With the continuous increase of graphics applications, the early solution of graphics rendering by CPU alone has been difficult to meet the graphics processing needs of performance and technology growth, and the graphics processing unit (Graphic Processing Unit, GPU) came into being. Since the release of the first GPU product by Nvidia in 1999, the development of GPU technology has mainly gone through the fixed-function pipeline stage, the stage of separating the dyer architecture, and the stage of unified dyer architecture. Rendering gradually extends to the field of general computing. The high-speed, parallel features and flexible programmability of the GPU pipeline provide a good operating platform for graphics processing and general parallel computing. ...
