Abstract
A texture caching controller, located on the graphics card, handles address logical-to-physical translation for texture addresses which are not downloaded to level-1 memory due to low use or dynamically changing values. This offloads texture memory management duties from the host.
Claims (4)
1. A graphics processing chip, comprising:
a graphics accelerator comprising rendering acceleration logic; and
a texture memory management function, integrated on said chip, which manages both texture storage in host memory and also texture storage in normal texture memory.
2. The chip of claim 1 , wherein said texture memory management function is able to read noncontiguous textures directly from said main memory.
