Embodiment

[0044] Below in conjunction with accompanying drawing the present invention is described in further detail, please refer to figure 1 .

[0045] The structure includes a parameter acquisition module 1 , a module 2 for calculating information of each layer and a module 3 for calculating single-depth Mipmap.

[0046] The acquisition parameter module 1 will receive and generate the Mipmap control signal, obtain the width, height and depth information of each Mipmap layer, and send the width, height and depth of the Mipmap layer to the calculation module 2 for each layer of information through the TLM interface.

[0047] The module 2 for calculating each layer of information will receive the width, height and depth of the Mipmap layer sent by the acquisition parameter module 1, and calculate the number of tiles in the x direction and the y direction, one-dimensional marks, and the last incomplete tile according to the above information. The mark, as well as the Mipmap depth value ...

Description

technical field [0001] The invention relates to the technical field of computer hardware modeling, in particular to a TLM microstructure for generating Mipmap multi-detail layer texture algorithms for GPU hardware. Background technique [0002] In the design and development of a graphics processor chip (hereinafter referred to as GPU), the correctness and efficiency of algorithms are important factors that determine the function and performance of the GPU. In order to improve performance, the GPU uses tiles (4x4 pixels) as the unit when storing / reading texture data. In order to unify the read and write interfaces, the calculation of Mipmap is also based on tiles (4x4 pixels). How to comprehensively consider one-dimensional, two-dimensional, three-dimensional texture processing, as well as classification of various edge cases, and an algorithm structure suitable for hardware implementation is a technical problem that needs to be solved urgently. GPU chip hardware has complex...
