A criteria is developed for the approximations of a logarithmic function to piecewise straight lines at multiple segments such that the maximum absolute error is minimized. The optimum cutting points for segmentation are estimated numerically with an exhaustive search. Our hardware implementation is restricted to integer operations (addition and shifting).
