Abstract

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 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/spl I.bar/Pro Xilinx tools.

使用CORDIC算法实现双曲函数

为了利用坐标旋转数字计算机CORDIC算法实现对数函数和指数函数，本文提出了一种新的双曲函数设计。FPGA能够在硬件中有效地实现CORDIC算法，这通常与“shift & add”硬件原语相关联。通过与泰勒精度的比较，选择了最佳的方程精度阶数。为了有效地实现CORDIC，引入了校正以保持在对数和指数收敛范围内。我们给出了使用ModelSim和Synplify/spl .bar/Pro Xilinx工具进行仿真和综合的结果和比较。
