State Machine Implementation
Figure 7-1 State Diagram
A state machine requires memory and the ability to make decisions.
The actual hardware used to implement a state machine consists of
state registers (flip-flops) and combinatorial logic (gates). State
registers store the current state until the next state is calculated, and a
logic network performs functions that calculate the next state on the
basis of the present state and the state machine inputs. The following
figure shows the logic transitioning through the state registers to the
output decoder logic.
