Design a combinational logic circuit using VHDL coding that executes the arithmetic and logic unit $($ALU$)$ functions below for the given inputs for registers $A,B$ and $G,$ which are $8$ bits each. $x$ is a binary input. Then execute the following mathematical operation:

$G=\{\begin{array}{cc}\frac{?}{?},& x=\\ ?{?}_{?}xo{r}_{?}+?{?}_{?}& \text{x}\text{o}\text{r}?{?}_{?}+?{?}_{?}\text{x}\text{o}\text{r}?{?}_{?}+?{?}_{?}\text{x}\text{o}\text{r}?{?}_{?},& x=\end{array}$
