operaciones - Suma o Resta en cada ALU

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;

entity operaciones is
    Port ( x : in std_logic;
           y : in std_logic;
           Carry_in : in std_logic;
           Sum : out std_logic;
           Carry_out : out std_logic);
end operaciones;

architecture Behavioral of operaciones is
begin
Carry_out <= ((x and y) or (Carry_in and y) or (Carry_in and x));
Sum <= ((x xor y) xor Carry_in);
end Behavioral;
