System and method for managing grain data in computer

Abstract

The present invention discloses a system and method for managing texture data in a computer, comprising the steps of: preloading a first plurality of texture descriptor values ​​from a storage location in a first buffer located in a first logic module , in response to a read request, wherein the first buffer is used to receive data located in the first logical block; from the storage location, the first plurality of texture descriptor values ​​are preloaded into a buffer located in a second logical block a second buffer; performing a shading calculation using the first plurality of texture descriptor values ​​in the second logical module; dynamically loading the second plurality of texture descriptor values ​​from memory into the first buffer, in response to the additional data requested by the first logic module; and overwriting a portion of the first plurality of texture descriptor values ​​with the second plurality of texture descriptor values ​​to reflect that the first buffer is full. The invention can reduce system redundancy and cost, improve texture processing operation, and improve operation.

Description

technical field [0001] The present invention relates to the processing of computer graphics data, and in particular to a system and method for managing texture data in a computer using a shared texture engine in a graphics processing unit (GPU). Background technique [0002] In today's many computer graphics processing, texture processing (Texture Processing) is undoubtedly the most critical part. Texture processing can include many different texture mapping (Texture Mapping) technologies such as: three-dimensional mapping (cubic mapping), mip mapping (mipmapping) and anisotropic mapping (anisotropic mapping) and so on. In static and dynamic modes, various textures can be applied to objects, which can also be thought of as texture prefetch before shader execution (Texture prefetch), just like dependent texture loading (Texture loading). It uses a large number of complex calculations and logic operations to complete texture processing, thus resulting in the need for additio...

AI Technical Summary

Problems solved by technology

Because it is necessary to provide dedicated texture processing hardware to locate, each prefetching and dependent reading texture method will increase the system redundancy, and will increase the cost due to the use of the processor. Therefore, the need to improve texture processing operations has existed in the industry. Long
