Use of Operator Overloading

Include these statements

at the beginning of a

design file

This allows us to perform

arithmetic on non-built-in

data types.

LIBRARY ieee;

USE ieee.std_logic_1164.all;

USE ieee.std_logic_unsigned.all;

ENTITY overload IS

PORT ( a : IN STD_LOGIC_VECTOR (3 downto 0);

b : IN STD_LOGIC_VECTOR (3 downto 0);

sum : OUT STD_LOGIC_VECTOR (4 downto 0));

END overload;

ARCHITECTURE example OF overload IS

BEGIN

adder_body:PROCESS (a, b)

BEGIN

sum <= a + b;

END PROCESS adder_body;

END example;
