【摘要】 双曲函数的应用领域十分广泛。首先介绍CORDIC算法双曲系统的基本原理及其计算模式,对CORDIC内核及前处理单元做了详细分析。在迭代算法的基础之上,采用流水线技术,以面积换速度,给出了一种基于流水线的CORDIC来实现反双曲正切函数,具有很高的精度和很快的速度,使设计出的软核能够在精度要求很高的场合中运行。用Verilog HDL对其编程设计,进行功能仿真和时序仿真,及下载测试,结果表明该函数具有很好的实用性。更多还原

【Abstract】 Hyperbolic functions are widely applied in many areas.This paper first introduces the principle of CORDIC algorithm hyperbolic system and its computation model,then it gives detailed analysis of pipelining CORDIC kernel cores and processor unit for the design.Based on the iterative algorithm,a new way of implementation hyperbolic functions based on pipelining CORDIC is proposed.It improves the calculation precision and speed at the cost of FPGA resource,making the soft core adapted to higher precision required occasion. Finally programming and designing the CORDIC,carries out the function simulation and timing simulation, downloading it to the FPGA,the result shows that it has a great practicability in practice.更多还原
