How to implement LOGRITHMIC in FPGA without using CORDIC?

Aircraft Maniac · Feb 23, 2003

Hi all,

I need help on how to implement LOGRITHMIC in FPGA without using CORDIC.

I thought of a very crude method of having a rough look up table method and then using Newton Raphsons Method to approximate the values.......

does someone have a better idea which also occupies lesser logic .

This paper is in Russian, however it has well-commented VHDL sources, so it will be easy for you to catch idea.
