Finite state machines (FSMs) are essential components of any sequential function in a system.FSMs are indispensable in the design of digital systems. To implement FSMs, the different states of the system need to be encoded and stored.
There are two main types of FSMs: Mealy state machines and Moore state machines. In Mealy machines, the output of the system depends on both the current state of the machine and the external inputs. On the other hand, in Moore FSMs, the output of the system depends solely on the current state of the machine. Mealy machines are more common in SOC (System on Chip) designs.
Figure 1 shows a Moore FSM. These diagrams illustrate the different states and transitions of the state machine and how the outputs are determined based on the type of FSM. FSMs play a importantrole in the functioning and control of various digital systems and are widely used in digital system design.
