Hyperpipeline
The order of the Hyperpipeline shows the order in which operations are
performed. The Scissor/Stipple unit is before the texture address
generator, so any fragments that fail a stipple test will not cause a
texture access. This makes best use of the processing capacity of the
pipeline. An awareness of the pipeline is important when programming
P
ERMEDIA
; all units in the pipeline can be thought of as independent. For
example, enabling the XOR logic op will not automatically enable
reading from the framebuffer; this must be done explicitly.
