Verilog implementation of Softmax function

Softmax is a non-linear logistic function commonly used in neural network circuits.

Softmax is denoted with the following equation.

Softmax graph

Taylor series approximation is used to calculate exponential which is donated as follow: f(x) = e^x = 1 + x/1! + x^2/2! + x^3/3! + ....
