Читать книгу Digital System Design using FSMs - Peter D. Minns - Страница 17

The answer to the previous question is:

In general: 2⁴ = 16 states, 2⁵ = 32 states, 2⁶ = 64 states, 2⁷ = 128 states, and so on.

What would the state number be for this FSM?

Answer:

The unused states would be s34 through to s63.

Note that the states run through from s0 to sn−1, for n states.

As well as containing flip‐flops to uniquely define the individual states of the FSM, there is also combinational logic, which defines the outside world outputs. In addition, the outside world inputs connect to combinational logic, which supplies the flip‐flops’ inputs.
