14. Build a GENERIC 1-bit ALU which can be used for the LSB, middle, and MSBs of an n-bit ALU with the above operations. Use a single 1-bit full adder, a single 4-input (2-bit selector) multiplexor, and an unlimited number of 2-input (1-bit selector) multiplexors and NOR gates. Efficiency is important; use the least amount of hardware. Carryin B 1-Bit ALU Result C1 0 0 1 | 1 Co || Operation 0 A XOR B 1 SLT (A B) - Set on Greater Than Less Carryouty Set control a. Using the GENERIC 1-bit ALU which you built, build a 4-bit ALU. Connect all appropriate wires and add any additional gates, unlimited number of 2-input (1-bit selector) multiplexors and NOR gates.
