Abstract:
1. An apparatus of reading texture data for texture mapping, the apparatus comprising: an odd numbered index cache memory to include a plurality of odd numbered index blocks having an odd numbered index; an even numbered index cache memory to include a plurality of even numbered index blocks having an even numbered index; and a controller to generate a read request with respect to requested texture data in the odd numbered index cache memory or the even numbered index cache memory based on at least two address indexes of the requested texture data, wherein the texture data is stored in an odd numbered index block or an even numbered index block based on an address in a main memory where the texture data is stored, wherein the controller determines whether all of the at least two address indexes of the requested texture data correspond to the odd numbered index cache memory or to the even numbered index cache memory prior to generating the read request, and wherein the controller extracts the at least two address indexes corresponding to at least two texture data having an identical row index from among the requested texture data.
