A graphic processing unit, a graphic processing system comprising the same, and a rendering method using the same. The graphic processing unit includes a geometry processing unit configured to receive a vertex and to output a primitive and information about texture patches corresponding to the primitive using the vertex, and a rendering processing unit configured to convert the output primitive into a fragment and to perform fragment shading on the converted fragment, wherein the texture patch indexed by the texture patch information is pre-loaded to the rendering processing unit before the fragment shading is performed.

Graphic processing unit for image rendering, graphic processing system including the same and image rendering method using the same

In systems and methods for graphic reproduction of an image including textural information, multiple rows or blocks of texture data can be retrieved from system memory in response to the single read command. In this manner, efficient use of system bus is achieved, and an increase in the texture cache hit ratio is realized, leading to more efficient system operation, and reduced system bus usage for texture data retrieval.

Systems and methods for storing and fetching texture data using bank interleaving

An apparatus according to an example embodiment of the present invention, may process data of a present span. During processing, data corresponding to an address of the start data of the next span may be prefetched from the external memory device based on information related to the presently processed data. The prefetched data may store in the cache memory.
