CORDIC on a configurable serial architecture for biomedical signal processing applications

The CORDIC (COrdinated Rotation DIgital Computer)[1] algorithm provides an efficient and accurate platform to compute various trigonometric, linear and non-linear functions using only shift-add operations. This paper presents the implementation of CORDIC algorithm on a configurable architecture to port various transforms which forms the heart of image and signal processing applications. We shall demonstrate this through the mapping of trigonometric, hyperbolic, logarithm and exponential CORDIC functions on the proposed architecture. Furthermore, we show the benefits of the architecture in terms of configurability and cycle timing with a reduced gate count implementation.
