Adding Texture Functions
Assume we always doing either linear blending (Undergrads) or trilinear filtering (grads)
Calculating ? takes two pipeline stages
Converting S,T to U,V takes one pipe stage.
- Calculation of a, b done in same stage
Texel Filtering
- Assume that we have an onchip texture cache that is wide enough to support 8 texel reads in 2 clocks.
- All texel reads done in one pipe stage
