ABSTRACT:
A method and apparatus allocates and stores texture data in a texture mapping computer graphics system. The data includes at least one series of texture MIP maps. The method includes the following steps: dividing each map of the at least one series of MIP maps into at least two map portions; allocating the map portions of each map into a plurality of equally-sized blocks of data such that portions of maps smaller in size than the size of a block are allocated within a single block; storing the blocks within a main memory of the system; and downloading the blocks at least one block at a time from the main memory to a local memory of the system. The step of downloading includes the step of downloading each block into one of first or second banks of at least one SDRAM.
