Efficient fault diagnosis for CORDIC Algorithm by using Hamming Codes

Abstract

The attractiveness of CORDIC Algorithm lies in the fact that by simple shift-add operations, it can perform several computing tasks such as the calculation of logarithmic, hyperbolic and trigonometric functions, real and complex multiplications, square-root, Eigen value estimation and many others. As a consequence, CORDIC has been used diversely for applications in diverse areas such as communication systems, 3- D graphics, signal and image processing apart from general scientific and technical computation. The digital computation is very much prone to errors; hence the error detection and correction became important for this algorithm. In this work it is achieved by integrating the Hamming codes to the CORDIC algorithm and hence achieving the error-free CORDIC algorithm. The proposed design are benchmarked through Xilinx FPGA and hence the reliability constraints be achieved.
