Implementation techniques of CORDIC: a review

  Gadhiya Ravindra B.,  Prof. Manisha C. Patel

The COordinate Rotation DIgital Computer (CORDIC) algorithm was introduced for performing computing tasks such as the calculation of trigonometric, hyperbolic and logarithmic functions, real and complex multiplications and many more using simple add and shift operation. CORDIC has been utilized for applications in diverse areas such as signal and image processing, communication systems, robotics and 3-D graphics apart from general scientific and technical computation. The CORDIC offers the opportunity to calculate all the desired functions in a rather simple way without using any hardware multiplier. The operations involved in the algorithm are addition, subtraction and bit shift with table lookup. Due to the simplicity of the involved operations the CORDIC algorithm is very well suited for VLSI implementation. In this article, we present a detailed overview of the CORDIC algorithm and review various architectures along with their potential and limitation.
