Abstract :
Real time digital signal processing requires the development of high performance arithmetic algorithms suitable for VLSI design. In this paper, a new online, circular coordinate system CORDIC algorithm is described, which has a constant scale factor. This algorithm was developed using a new Angular Representation (AR) model. A radix 2 version of the CORDIC algorithm is presented, along with an architecture suitable for VLSI implementation
