Barrel Shifter VHDL Code with diagram to learn

Barrel Shifter: Rotates 8-bit input by a specific amount. Problem with large input (e.g., 32 bits) – Large multiplexing structure – Lengthy code – Better alternative Barrel Shifter VHDL Code:library ieee;use ieee.std_logic_1164.all;entity barrel_shifter is   port(      a: in std_logic_vector(7 downto 0);      amt: in std_logic_vector(2 downto 0);      y: out...
