library ieee;
use ieee.std_logic_1164.all;

entity SISO is
port (clk : in std_logic;
rst : in std_logic;
s_in : in std_logic;
s_out : out std_logic);
end SISO;

architecture s1 of SISO is
begin
process(clk,rst,sin)
begin
if(rst='0') then
sout <= 1'b0;
elsif(clk='1' and clk'event) then
sout <= sin;
end if;
end process;
end s1;

Hi,
Can you clearify your need? what kind of process you want to be done on input data? do you really want to just give serial data from one hand and put it outside with another hand? both input and outout are serial?

24 Jul 2008 11:07 vhdl coding spartan 3a

Actually I want to communicate my spartan-3a starter kit with hyperterminal and want to display on LCD ,what i write on hyperterminal. I got a vhdl code on website www.OPENCORES.org . But now i am unable to find all the pinouts defined in that code. I know only pinouts for RxD & TxD. If someone can help me then please post your views.
Thank you.
