juchi_address.vhd

采用DDS技术的波形发生器(FPGA实现)

library ieee;
use ieee.std_logic_1164.all;
use ieee.std_logic_unsigned.all;

entity juchi_address is
port(
     clk:in std_logic;
     addin:in std_logic_vector(9 downto 0);
     addout:out std_logic_vector(7 downto 0));
end;

architecture delta of juchi_address is
signal count:std_logic_vector(7 downto 0);
begin
   process(clk)
    begin
     if rising_edge(clk) then
