Finite State Machine Minimization

Finite State Machine Minimization. 8 synchronous sequential circuits 8.6 state minimization. The term minimization refers to the construction of finite automata with a minimum number of states, which is equivalent to the given finite automata.

In automata theory, dfa minimization is the task of transforming a given deterministic finite automaton into an equivalent dfa that has a minimum number of states. Reducing doesn't mean compromising for performance. 3) examine each class c in the currentπand find each state q in c such that δ(q,c)isastateins.letc!⊆ c be the set of such states.

Remove All The States That Are Unreachable From The Initial State Via Any Set Of The Transition.


The smallest deterministic finite automaton m' such that m' behaves identically to m. Let automata a1 and a2, (these designations can refer to the same automaton) under the influence of any input sequence produce the same output sequence, that is, automata a1 and a2 in these states q i and q j indistinguishable by external exits. The minimization of the number of states of complete automata is related to the equivalence relation.

Take Action Early And Often.


Complicated control systems and compilers are often built using finite state machines to encode the current state and associated actions, as well as the set of possible transitions to. The number of states used in finite automata directly depend upon the size of the automata that we have used. We can now define a procedure for the minimization of an arbitrary finite state machine with q states.

In This Method, Such Optimization Criteria As The Power Consumption.


The fsm can change from one state to another in response to some inputs; In the definition of equivalent, it will be initial state rather than final state Once the “raw†design fulfills our requirements, we concentrate on reducing the same design.

In This Method, Such Optimization Criteria As The Cost Of Implementation, Power Consumption, And Speed Of Operation Are Taken Into Account Already At The Stage Of Minimizing Internal States.


We can then easily check if two dfsm are are equivalent. 1) remove one class, call it s,froml,andconsidereverycharacter inσto be unmarked. We just need to check if they have the same number of states and if all the transitions are the same.

• Design State Diagram Without Concern For # Of States, Reduce Later 0 S0 [0] S1 [1] S2 [0] 1 S0 [0] S1 [1] 0 1 1 0 0 0 1 1.


Shift from reactive to proactive and ensure that products are secure by design. Thus, we get the fsm(finite state machine) with redundant states after minimizing the fsm. But the coolest thing about finite state machines is the fact that they can be minimized.
