An arithmetic logic unit (ALU) is a major component of the central processing unit (CPU) of a computer system. It is a digital circuit used to perform arithmetic and logic operations, including bit-shifting operation. (i) Design the following logic circuit/components using Verilog synthesizable code. a 16-bit OR a 8-bit Multiplier . a 16-bit Subtractor a 16-bit Sign and Magnitude ADDER (ii) Construct an ALU with 4-functions using bottom-up method that instantiates the previous four components and selects one output based upon the Mode as shown in Table 1.
