---实现的部分VHDL 程序如下。
--- elsif clk1x event and clk1x = 1 then ---if std_logic_vector(length_no) >= “0001” and std_logic_vector(length_no) <= “1001” then -----数据帧数据由接收串行数据端移位入接收移位寄存器---RSR(0) <= rxda --- RSR(7 downto 1) <= RSR(6 downto 0) --- parity <= parity xor RSR(7) --- elsif std_logic_vector(length_no) = “1010” then --- rbr <= RSR --接收移位寄存器数据进入接收缓冲器--- ...... --- end if
