Design a 4-bit arithmetic combinational circuit that performs the following operations: Control Inputs Operation S(A,B) 0if (A/4-0) then S- A B 0 | if(A?B) then S A + (B * 8); else S A (B/4 S-A +4 0 ** Both A and B are 4-bit binary unsigned numbers (aza2a1ao) and (b3b?bibo) * Mi, Mo are the control inputs to the arithmetic unit, based on the values of Mi and Mio the arithmetic unit performs a specific operation. * S is the 4-bit output of the arithmetic unit (s3s2S1So) ** B*8 is the result of performing integer multiplication of the 4-bit number B by 8. ** A/4 is the result of performing integer division of the 4-bit number A by 4. * In this question you are required to design the combinational logic circuit inside the arithmetic unit using the minimum number of the following components: 4-bit Comparator (74LS85), 4-bit binary Full adders (74LS83), 4:1 Multiplexers (74LS153). and 2:1 Multiplexers. Hint: If 2:1 multiplexers are not available, replace them with 4:1 Multiplexers. ** Although the inputs and outputs are unsigned numbers, you can use 2's complement arithmetic within the design of your circuit once needed.
