Area efficient architecture of Hyperbolic functions for high frequency applications

Abstract

CORDIC algorithms are used for low cost hardware implementation to calculate elementary functions like trigonometric functions, hyperbolic functions, square root etc. This paper presents an area-efficient multiplier-less architecture for computation of exponential and hyperbolic functions. It has been implemented on Virtex-4 FPGA kit and Altera Quartus -II kit. The proposed architecture is suitable for applications that require high frequency as its frequency of operation is higher than the existing architectures reported in literature.
