摘要：

In this paper, we present a new design of hyperbolic functions in order to implement logarithm and exponential functions using CORDIC algorithm (COordinate Rotation DIgital Computer). FPGA enable effective implementation of CORDIC algorithm in hardware, which is usually associated with "shift & add" hardware primitives. A comparison with Taylor precision was be done to choose the best equation precision order. To valid CORDIC implementation, correction was introduced to remain in logarithm and exponential convergence range. We present simulation and synthesis results and comparison using ModelSim and Synplify_Pro Xilinx tools.
