Coding shift register is quite a simple task. In actual hardware the shift register is implemented as a sequence of flip-flops connected in a series, where the data keeps shifting from one flip-flop to another with every clock edge. As shown in 4-bit shift-register below.
Lets see how a 8-bit shift-register implemented in VHDL...
|8 bit Shift-Register|
1) shift_reg : PROCESS(clk_sig, reset_sig) 2) BEGIN 3) If(reset_sig = '0') THEN 4) out_1_sig <= "00000000"; 5) ELSIF(clk_sig 'event AND clk_sig = '1') THEN 6) IF (enable_sig = '1') THEN 8) out_1_sig(7 DOWNTO 1) <= out_1_sig(6 DOWNTO 0); 7) out_1_sig(0) <= data_in_sig; 9) END If; 10) END If; 11) END PROCESS;
From the above code it is quite clear that first the 7 bits (6 downto 0) are placed at (7 downto 1) and the input bit "data_in_sig" is placed at 0th bit. This is same as shifting each bit by one position.
Here note that the MSB bit (7th) will be lost, every time a new bit enters the shift register.
Yuvraj Toor it's kinda bad. because they are supposed to be real. But to be honest. All of these new Jordans are replicas of the original. They do not use real leather on shoes anymore. It's a slippery slope
Talk about bootleg quality., . my mans wore them shits for 2 years! Some of my official Nike shit blows out after 6 months, so shout out China for your bootleg quality on the come up. (even tho in some cases the bootlegs are made in the same place as the officials
