This paper describes a special processor based on the CORDIC algorithm, which can perform a variety of trigonometric, hyperbolic and square-root functions as well as multiplications and divisions. The paper suggests an efficient processing element for pipelined realizations of three-dimensional transformations occuring in computer graphics and robotics. Modified floating-point arithmetic is used to avoid convergence problems and to guarantee high accuracy and an enlarged data range with only a moderate overhead of hardware cost. (IMS)
