4.44 Using a case statement, write an HDL behavioral description of an eight-bit arithmetic-logic unit (ALU). The circuit has a three-bit select bus (Sel), 16-bit input datapaths (A and B), an eight-bit output datapath (y), and performs the arithmetic and logic operations listed below. Sel Description Reset y to all O's 001 Bitwise AND 010 Bitwise OF 011 Bitwise exclusive-OR 100 Bitwise complement 101 Subtract 110 Add (Assume A and B are unsigned) Set y to all 1's
