求助，请帮忙看一下为什么总是运行不了，谢谢

请各位帮忙看一下这两个并串转换的小程序，为什么总是运行不了，谢谢
第一个：
LIBRARY IEEE;
USE IEEE.STD_LOGIC_1164.ALL;
use ieee.std_logic_unsigned.all; --并串转换
ENTITY bingchuan IS
PORT (RESET :IN STD_LOGIC;
CLK : IN STD_LOGIC;
DIN : IN STD_LOGIC_VECTOR(7 DOWNTO 0) ;
DOUT :OUT STD_LOGIC
);
END bingchuan ;
architecture bhv of bingchuan is
SIGNAL COUNT : STD_LOGIC_VECTOR(2 DOWNTO 0);
SIGNAL DAOUT : STD_LOGIC ;
BEGIN
PROCESS (CLK,COUNT,RESET)
BEGIN
IF RESET='1' THEN COUNT
