I finished the first part and its code below:
architecture Behavioral of alu is
begin
process(a,b,s) is
begin
case s is
when “00” => result <= a and b;
when “01” => result <= a or b;
when “10” => result <= a xor b;
4. Write the VHDL code for the 1-bit ALU with three functions shown in the Figure: 1-bit ALU Operation Operation 00 and 01 or 10 XOR 1 H r Result 5. Extend the ALU in problem four to 4-bit and writ the VHDL code for it.
