A rasterizer stage configured to implement multiple interpolators for
graphics pipeline. The rasterizer stage includes a plurality of
simultaneously operable low precision interpolators for computing a first
set of pixel parameters for pixels of a geometric primitive and a
plurality of simultaneously operable high precision interpolators for
computing a second set of pixel parameters for pixels of the geometric
primitive. The rasterizer stage also includes an output mechanism coupled
to the interpolators for routing computed pixel parameters into a memory
array. Parameters may be programmably assigned to the interpolators and
the results thereof may be programmably assigned to portions of a pixel
packet.
