Abstract
Some application possibilities of an ASIC-type processing element, the CORDIC processor, in computer graphics are discussed. CORDIC-based solutions are derived for some basic computer geometry computations: conversion between coordinate systems, rotations, point-line and pointplane distance calculations, ray-patch intersection computations, intensity and scalar product calculations. The main results are the following. Some basic computational tasks of computer graphics can be advantageously implemented using CORDIC arithmetic. The CORDIC processing element can serve as a building block even in high performance parallel graphics systems. A short example compares the possibilities of the CORDIC-based solution to the performance of the well-known polygon rendering with Pixel-planes.
