Abstract
A circuit for texture tag checking includes a first comparison gate which compares a first dimension field of a tag with a first dimension element for a group of texels associated with a sample point. A second comparison gate compares a second dimension field of the tag with a second dimension element for the group of texels. A logic gate, coupled to each of the first and second comparison gates, is associated with one texel of the group of texels. The logic gate outputs a predetermined signal if the first and second dimension fields of the tag are the same as the first and second dimension elements, respectively.
