Embodiment

[0046] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Such as figure 1 As shown, a GPU multi-threaded texture mapping SystemC modeling structure adopts SystemC language and Transaction Level Modeling (TLM, transaction level modeling) method, and each functional module in the model passes the function of the transaction level interface, rather than through the hardware signal Connected to achieve communication, each module contains its own independent, parallel execution process, each process has only one common event trigger - clock rising edge, cycle-accurate hardware modeling of the texture mapping unit; each Processes can call functions in the transaction-level interface of their respective modules to transfer information to each other.

[0048] The mapping unit includes a texture parameter acquisition and Level calculation unit (1), a texel address ...

Abstract

The invention belongs to the field of computer graphics, and especially relates to a GPU multi-thread texture mapping SystemC modeling structure. The structure comprises a texture parameter obtaining and Level calculation unit (1), a texel address calculation unit (2), a data assembly and task distribution unit (3), a texel data extraction and format conversion unit (4), a texel filtering and texel data normalization unit (5) and a texture mapping state and control parameter unit (6). The structure can avoid the tedious circuit signal design, quickly evaluates the framework of a large-scale hardware system, is suitable for the early system-level design and development of a circuit, and provides an effective reference for the same type of products and functions.

Description

technical field [0001] The invention belongs to the field of computer graphics, in particular to a GPU multi-thread texture mapping SystemC modeling structure. Background technique [0002] Texture mapping is to paste various texture images on the surface of the 3D graphics generated by the computer to improve the realism of the graphics. Texture mapping belongs to the pixel processing stage and is used to speed up computation-intensive and storage-access-intensive texture operations. One of the main operations is to find out the storage space of the texel corresponding to the screen space pixel (x, y, z) in the texture space. The address (that is, the texel address), and then filter the selected texture element color, and replace the pixel color of the screen space with this value, thus completing the texture mapping. That is to say, the pixel coordinates of the screen space are first converted to the parameter space (u, v), and then converted from the parameter space to t...
