Abstract
A method and an apparatus for retrieving a mipmap from memory. The method and apparatus provide an efficient method of determining the location of the desired mipmap in memory by storing the address of each row of mipmaps and calculating the offset from the start of the row to the desired mipmap. The mipmap is retrieved from memory at the location corresponding to the sum of the start address and the offset.
