RUN-TIME RECONFIGURABLE FABRIC FOR 3D TEXTURE FILTERING SYSTEM

Abstract

The present invention discloses a texture filtering system, comprising a sequence generator, a retrieve unit and a dispatch unit. The sequence generator generates an execution sequence in each duty cycle. The execution sequence is the priority of respectively retrieving multiple pixels from multiple queues. The retrieve unit outputs multiple Boolean signals based on the limitation of the total number of all-purpose texture filters and the above priority in a duty cycle for determining from which queues the pixels are retrieved to perform a texture filtering process, and the dispatch unit assigns the multiple texture filter formats of the pixels to be processed and the anisotropic ratios thereof to multiple address generators. Besides, the present invention utilizes Brute force method to enable multiple bilinear texture filters to satisfy the various texture filter formats of a pixel, thereby markedly reducing the space occupied by the texture filter in a 3D graphic processing unit, provided that the specifications of the address generators and texture cache memory are unchanged.
