Fragment Processor
The fragment processor will operate at a particular clock rate and contain a number of pipeline stages for performing fragment operations.
A pipeline stage holds all the data for a fragment
- X,Y,Z, R,G,B,A, Fog factor, Fog Color, etc
#pipe stages = #of Frag Ops/ (clks per fragment)
clks per frag = (Max clock Rate * Frag Processor Width)/Frag Rate
Fragment Processor Width measured in Fragments.
Width > 1 indicates parallel fragment processing pipelines.
