design a 4 bit comparator that compares two numbers of 4 bits. the output should be < > or =. however you're only limited to using multiplexers or full adders. any help on how to draw this will be appreciated
The truth table of the 4bit comparator is given below
In order to implement the above circuit with fewer gates, we modify the circuit that is shown in the following figure
In order to reduce the area, we can still decrease the number of gates. The logic of A<B can be decided by A>B and A=B, so we can simplify the above circuit as below. 2-input NOR is used here to realize the function of A<B.The area of 2-input NOR is much less than that of G11~G15. On the other hand, fewer gates means fewer power, so this modification can greatly reduce the power dissipation. Therefore, the logic optimization is completed.

For number 2 you can use exclusive-OR gates, but do not use multiplexers. 1. Design a 4-bit adder/subtractor using only full adders and EXCLUSIVE- OR gates. Do not use any multiplexers. 2. Design a combinational circuit using a minimum number of Full adders, and logic gates which will perform A plus B or minus B (A and B are signed numbers), depending on a mode select input, M. If M=0, addition is carried out; if M1, subtraction is carried out....
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 combinational circuit which compares two 4-bit unsigned numbers A and B. The circuit should have one output X such that X = 1 whenever A>B and X = 0 whenever A?B. You may use any MSI modules as well as any other gates.
design and build a 4 bit binary multiplier that multiplies two 4 bit unsigned positive numbers to generate a 8 bit unsigned positive number. using full adders. do not use 4 bit multiplier chip. use truth table, karnaugh map and simplified output expression of the circuit.
Design a combinational circuit that compares two 4-bit unsigned numbers A and B to see whether B is greater than 2A. The circuit has one output X, so that:X = 1 if 2A < B, andX = 0 if 2A >= B.Please de descriptive and detailed in drawing.The book we are using in class is this: http://www.cramster.com/logic-and-computer-design-fundamentals-4th-solutions-3631 and we are on chapter 4.
Design a combinational circuit that compares two 4-bit unsigned numbers A and B to see whether A is greater than B. The circuit has one output X, so that X = 0 if A ≤ B and X = 1 if A > B.
