b) Incorporate the Carry Lookahead Adder into the above 4-bit ALU. Show the modified hardware. c) Incorporate the Comparator with Lookahead into the above 4-bit ALU. Show the modified hardware. Problem #1: This problem involves the design of a bit sliced ALU (Arithmetic and Logic Unit). The ALU is capable of several Arithmetic and logic functions, depending on the select code. Si lin- ALU BIT SLICE function Complement A Add A, B - Shift A left Shift A right A and B Out (ith module) Out Axor B A or B Out Step 1: Complete the following table. | 000 Out Out (AIBI) lin+AIBI Al Bilin, Step 2: Show hardware interconnections of one ALU BIT SLICE. Step 3: Show module interconnections for a 4-bit ALU. b) Incorporate the Carry Lookahead Adder into the above 4-bit ALU. Show the modified hardware. c) Incorporate the Comparator with Lookahead into the above 4-bit ALU. Show the modified hardware
