Here, Young discloses "[a] 3D graphics processing system," col. 1, l. 17, which
includes a "graphics engine ASIC 22. . . ." Col. 3, l. 5. The graphics engine "takes
vertex data from the graphics FIFO 21 and produces rendered spans of pixel data." Id.
at ll. 6-8. In turn, "[t]exture processors 251-254 receive two types of setup parameters
from the graphics engine 22: one type for triangles and one type for pixel
spans within a triangle." Col. 6, ll. 29-31 (emphases added.) "[T]he pixel span
setup parameters consist of initial texture coordinates." Id. at l. 33-34 (emphasis
added). The four texture processors shown in Figure 2 of the reference evidence that
Young's texture coordinates, including its initial texture coordinates, comprise a red
texture coordinate, a green texture coordinate, a blue texture coordinate, and an alpha
texture coordinate.
Because the claimed addresses and the reference's coordinates both specify a
location, and "[a] 'texel' is used to represent the coloration values of a corresponding
