1.In VHDL, create a component for each of the operations in table1 and any other components you may need to implement the ALU.

2. Create the toplevel VHDL file that instantiates the components to create the 4bit five function ALU

3. Write a selfchecking testbench to exhaustively test your ALU

4. Inputs are 4 bit vector.
