Synthesizable Factorial VHDL-->N ! = N x (N-1) x (N-2) …. x 2 x 1

The function we want to implement in hardware is the well-know Factorial noted with an exclamation mark :
0 ! = 1 (by convention)
1 ! = 1
N ! = N x (N-1) x (N-2) …. x 2 x 1
This function is easy to define using recursion :
N ! = N x (N-1) !
We'll see that we can code the recursion while keeping the code synthesizable.
