The FPGA Implementation of Hyperbolic Arctangent Function
Duan Ji-hai · Computer Engineering and Science · 2009
Hyperbolic functions are widely applied in many areas.This paper first introduces the principle of the CORDIC algorithm hyperbolic system and its computation model,and then gives a detailed analysis of pipelining the CORDIC kernel and its processor unit for the design.Based on the iterative algorithm,a new way of implementing hyperbolic functions based on pipelining CORDIC is proposed.It improves the calculation precision and speed at the cost of FPGA resources,making the soft core adapted to higher-precision-required occasions.Finally the results of programming the CORDIC,performing the functional simulation and timing simulation,and downloading it to the FPGA show that it features great practicability.
