在VHDL中,可以使用buffer例化来实现信号的缓冲。下面是一个使用buffer例化的示例代码: library ieee; use ieee.std_logic_1164.all; entity BufferExample is port ( input_signal : in std_logic; output_signal : out std_logic ); end BufferExample; architecture Behavioral of BufferExample is signal buffer...

举个例子,设计一个计数器的时候可以将输出的计数信号定义为BUFFER,这样回读输出信号可以做下一计数值的初始值,buffer顾名思义就是缓存,它是作为输出使用的,因为在模块内,是不可以将输出赋值给其他信号的,例如定义b: out std_logic;我们现在要将b赋值给信号a,就会出错,但是如果b的类型为buffer就可以执行操作; ...
PORT ( clk : IN STD_LOGIC; out2 : BUFFER STD_LOGIC); END freq_divider; --- ARCHITECTURE example OF freq_divider IS BEGIN PROCESS (clk) VARIABLE count2 : INTEGER RANGE 0 TO 7; BEGIN IF (clk'EVENT AND clk='0') THEN count2 := count2 + 1; IF (count2 ...

The other major use for this type is the quoting and escaping logic in Query's stream interface: rather than overload the << operators and the manipulators for every single type we know the rules for a priori, we just specialize the manipulators for SQLTypeAdapter. The conversion to SQLTypeA...
signal C_INT : STD_LOGIC_VECTOR(3 downto 0); begin C <= C_INT; process begin if (CLK'event and CLK='1') then C_INT <= A and B and C_INT; end if; end process; end BEHAVIORAL; For more information on ports, see the Synthesis and Simulation Guide, as well as the ISIM User...
