9) (2 points) You are given two, 3-bit, two's complement integers A[2:0, B(2 : 0). You are asked to design a two's complement (signed) comparator circuit that produces f = 1 when A > B; otherwise f = 0. Design the above circuit (block diagram) assuming that you are given: i) pre-designed 3-bit unsigned comparators (f = A > B), ii) MUXes, and iii) any AND/OR/XOR/NOT Boolean logic gates.
Following the circuit specification below: Comparator: A 3-bit comparator has six inputs A= A2A1A0 and B= B2B1B0, and one output: L. The comparator is a ‘less than’, meaning the output is ‘1’ is A<B. Using your method of choice, find the Boolean expression for the output of the comparator; Draw the logic circuit of the 3-bit comparator Available gates (no other gates can be used than the 5 listed below): 2-input NAND 2-input NOR 2-input AND 2-input OR Inverter
2. Build an 8-bit comparator that compares unsigned numbers A = a7 ao and B = b1" . bo and outputs 1 if A > B . First build a smaller unit (using K-map) with logic gates that compares two bit numbers X=x1x0 and Y =y,yo. Then, use sufficient number of these elements with required additional gates to build the final circuit.
4. Design a 4-bit Adder / Subtractor. Follow the steps given below. (a) Write the VHDL code for a 1-bit Full Adder. The VHDL code must include an entity and an architecture. (b) Draw the circuit diagram for a 4-bit Adder / Subtractor. The circuit diagram may include the following logic elements: 1-bit Full Adders (shown as a block with inputs and outputs) Any 2-input logic gates Multiplexers Do not draw the logic circuit for the 1-bit Full Adder.

Using building blocks such as binary adders, comparators, multiplexers, decoders, encoders, and arbiters as well as logic gates, design an 8x2 popularity circuit – a circuit that accepts eight two-bit numbers and outputs the number of times each of the four numbers appears on the input.
Design a 2-bit full adder. this circuit would have 5 inputs, two for the number A = (a1,a0), two for the number B = (b1,b0), and one for the carry-in Cin. It would also have three ouputs, two for the sum bit S = (s1,s0) and one for the carry out Cout.

A comparator circuit has two 1-bit inputs A and B and three 1-bit outputs G (greater), E (equal), and L (less than). That is, G is 1 if A > B (0 otherwise), E is 1 if A == B (0 otherwise), and L is 1 if A < B (0 otherwise). a. Draw the truth table for a 1-bit comparator (the table has 2 inputs and 3 outputs). b. Implement G, E, and L circuits using only...
