Additional State Machine Design Examples
1. Design a Moore machine state diagram for a sequence detector that outputs a 1 after receiving a
sequence with at least one 1 and three 0s in
NEW DISCOVER FOR FSM (OVERLAPING)!
Let see first example!
Step 1: Identify the number for each bit.
1st bit = > 1
2nd bit => 0
3rd bit => 1
Step 2: Create a draft state table.
Step 3: List out all possible curre
Laboratory Exercise 6
Adders, Subtractors, and Multipliers
The purpose of this exercise is to examine arithmetic circuits that add, subtract, and multiply numbers. Each
type of circuit will be implemented in two ways: rst by writing VHDL code that describ
Laboratory Exercise 2
Numbers and Displays
This is an exercise in designing combinational circuits that can perform binary-to-decimal number conversion
and binary-coded-decimal (BCD) addition.
We wish to display on the 7-segment displays HEX3 to HE
Laboratory Exercise 4
This is an exercise in using counters.
Consider the circuit in Figure 1. It is a 4-bit synchronous counter which uses four T-type ip-ops. The counter
increments its count on each positive edge of the clock if the Enab
Laboratory Exercise 5
Clocks and Timers
This is an exercise in implementing and using a real-time clock.
Implement a 3-digit BCD counter. Display the contents of the counter on the 7-segment displays, HEX20. Derive
a control signal, from the 50-MHz
DE1 Development and Education Board
Thank you for using the Altera DE1 Development and Education board.
The purpose of this board is to provide the ideal vehicle for learning about digital logic, computer organization,
and FPGAs. It uses the state-of-the-

materials provided by the Altera Corporation. It also explains the installation process needed to use a DE1
1. Draw state diagram of Mealy and Moore machines
for a sequence detector system which the outputs a
1 when exactly two of the last three inputs are 1.
2. What is the sequence that needs to be detected by the
system? Moore or Mealy?

Finite State Machines
Combinational Logic Units
Combinational logic units are a type of
logic circuit whose output is a pure
function of the present input only.

Mealy state machine
In the theory of computation, a Mealy machine is a finite state transducer that
generates an output based on its current state and input. This means that the state
diagram will include both an input and output signal for each transitio
