H1

Consider the following state machine:
The state machine will perform an
arithmetic function on two 4-bit
numbers.
The inputs are:
A: A 4-bit number
B: A 4-bit number
SEL: A button that selects the desired
function.
The outputs are:
Q: The current state (2 bit)
Result: An 8-bit number that holds the
result of the desired arithmetic function.
States: There are three states:
= 00: Add
= 01: Subtract
Q = 10: Multiply
The state machine jumps from state 00,
to 01, to 10, and back to 00, when the
input F
changes from a 0 to a 1.
1. Draw a state diagram to implement the
state machine:
2. Make a state transition table for the
state machine.
