Abstract: A generic interpolation pipeline processor for use in a real-time video display system to find the coordinates of any point P(x,y) on a line between P.sub.1 (x.sub.1,y.sub.1) and P.sub.2 (x.sub.2,y.sub.2) according to the equation ##EQU1## The processor includes an apparatus for performing integer interpolation calculations using a single independent variable to calculate two dependent variables in parallel and further includes apparatus for merging division and multiplication operations so as to increase throughput as compared to a division pipeline followed by a multiply pipeline.
