基于vhdl的串并转换器 首先,用变量时最好初始化一下variable t:std_logic_vector(2 downto 0):=\"000;要不一开始输出是个不确定值。还有就是这段写得不规范,改一下if clk'event and clk='1' thenif i=3 thenDout3(2);Dout2(1);Dout1(0);i:=0;elset(2 downto 0):=t(1 downto 0)&din;i:=i+1;end if;end if;

用VHDL设计一个五位二进制如何转换为十进制的程序? 很简单,VHDL里面有一个二进制转十进制函数CONV_IETEGER(),在UNSIGNED这个程序包里,打开它用就是了,程序如下,LIBRARY IEEE;USE IEEE.STD_LOGIC_1164.ALL;USE IEEE.STD_LOGIC_UNSIGNED.ALL;ENTITY TURN2_10 ISPORT(A:IN STD_LOGIC_VECTOR(4 DOWNTO 0);B:OUT INTEGER RANGE 0 TO 32);END;ARCHITECTURE ART OF TURN2_10 ISBEGINB(A);END;
