Abstract
In this paper, we propose a low-cost sequential architecture for the implementation of CORDIC algorithm in two computation modes. It suited for serial operation that performs conversion between polar and rectangular coordinate systems, essentially sin/cos, sinh/cosh and arctan computation. The design targets real time application of fingerprint recognition. We present a VHDL description of CORDIC algorithm. To reduce iteration delay, we used some combinatory blocks. Fixed point arithmetic was considered. To valid our conception and its CORDIC accuracy, we present relative error calculated in convergence range for some trigonometric and hyperbolic functions. All measurements show an enhancement compared with our previous work. The architecture was implemented and tested. The contribution of the paper includes the CORDIC design flow.
