你采用的信号标识符count和变量标识符count混淆到一块去了。在结构体的端口声明中，已经将count声明为端口信号了，在进程中声明变量时，应当采用其它标识符。特别是在最后一个进程中没有声明变量count，却在关系表达式中出现了count，编译器自然会将这个count认定为是端口信号count。
错误说明你mod运算的库没调 library ieee;use ieee.std_logic_1164.all;use ieee.std_logic_unsigned.all;use ieee.numeric_std.all;use ieee.std_logic_signed.all;use ieee.std_logic_arith.all;应该是这边少了个运算的库，好久没用VHDL了，忘记什么库了 如果不是这个原因，当我没说 ...
LIBRARY IEEE;USE IEEE.STD_LOGIC_1164.ALL;USE IEEE.STD_LOGIC_unsigned.ALL;USE IEEE.STD_LOGIC_arith.ALL;添加以上库试试。
