Part 1- Combinational circuit to determine the operations to be used in 8-bit unsigned calculator. (1 Marks)
Identify the input and output variables.
Write the truth table
Simplify the output function
Implement the function as a sub-circuit in circuitverse.org and attach a screenshot of the circuit design (see the appendix on how to make a sub-circuit Part 2 – consider the result of previous circuit is the type of operation you will use. Insert using keyboard or manually two numbers to be calculated (add, sub, multiply or compare). You should use sequential circuit comparator. You will use 8-bit unsigned numbers.
Design 8-bit adder-subtractor that add/sub two input numbers.
Design 8-bit multiplier that multiply two input numbers.
Design and implement sequential circuit that compares two input numbers.
A reset signal resets the comparator to its initial state. Reset is required before starting a new comparison.
Two outputs: any value you specify as (Greater Than) and any value you specify as (Less Than).(you should determine the value on the beginning of your answer)
show state diagram, state table, k-map simplification, and circuit diagram with used flipflop.
Implement the calculation and show in table at least 5 results for each operation. Write your observation.
Implement each operation as a sub-circuit in circuitverse.org and attach a screenshot of the circuit design (see the appendix on how to make a sub-circuit)
Part-3 – Combined circuit connecting the whole calculator of four functions with selector in part 1 together.
Create the full circuit.
Test the circuit with different inputs to make sure it functions correctly.
Part 4: Provide a link to your implementation in circuitverse.org
