Design a combinational circuit design that given a four-bit
number as the input outputs an 8-bit number that represents the nth
Fibonacci number in the sequence. For instance, if the input is
0001, the output should be the second number in the Fibonacci
sequence. The Fibonacci series looks like the following: 0, 1, 1,
2, 3, 5, 8, 13, and so on. The first two numbers in the sequence
are always 0 and 1. However, after that, you must add the previous
two numbers in the sequence to get the next one.

Design a combinational circuit which inputs a three-bit binary number, and outputs the input number PLUS two if the input is less then or equal to 3, and outputs the minus two if the input is greater than 3. This should include the truth table for the operation, the karnaugh map(s), and the resulting circuit.
Design a combinational circuit that accepts a 3-bit binary number input x and generates a 6-bit binary number output equal to the xth Fibonacci number F(x) = F(x-1) +F(x-2) where F(0) = 2 and F(1) = 3.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 3.
Combinational logic: a) Design a circuit to compare two numbers each is 1-bit: A, B. With 3 outputs X for A-B ,Y for A<B, Z for A B b) Use the previous output (or only one of them) as selection lines for a multiplexer to give the larger number to the output of the multiplexer.
Fibonacci: case. Write a VHDL description for a circuit that accepts a four-bit input and outputs true if the input is a Fibonacci number (0, 1, 2, 3, 5, 8, or 13). Your implementation must be done via a case statement.
2. Design a circuit that outputs 0 if the two 4-bit numbers input are not equal and outputs 1 if they are equal.
We want to design a circuit that takes as input a serial bit stream and outputs a 'l' whenever the sequence “111” occurs. Overlaps must also be considered. For instance, if... occurs, then the output should remain active for three consecutive clock cycles. 3.1) Draw the state diagram of the finite state machine. 3.2) Write the System Verilog model for the design.
Design a sequential circuit that outputs 2’s complement of a bit sequence. The bit sequence will be given to the circuit in reverse order. For instance, if the given bit sequence is 0010101000, the circuit should output 1101011000.
Design a Combinational circuit that forms that form the 2-bit binary Sum S1S2 of two 2-bit numbers X1X0 and Y1Y0 and can produce a carry ouput C. Design the entire circuit with the help of three half adder circuits implementing each of the three outputs with XOR-AND and OR gates
3) [9 marks] Using the combinational circuit design procedure discussed in the notes, design with a truth-table, simplify with K-maps, and draw the combinational circuit that accepts a 3-bit number and generates a 5-bit number output equal to 3X + 2 where X is the input number (if the input is 010 (2), the output should be (01000) 8 . Let the inputs be A, B, C and the outputs be V, W, X, Y, Z.
Design a combinational circuit that accepts a 2-bit number and generates a 4-bit binary number output equal to the square of the input number. Use Decoder and any other external gates as necessary to implement your design. Draw the logic diagram and clearly label all input and output lines.
