One-Hot State encoding has the following attributes:
- Is the default encoding scheme for a state machine, up to 32 states.
- Is usually a good choice for optimizing speed or reducing power dissipation.
- Assigns a distinct bit of code to each FSM state.
- Implements the State Register with one flip-flop for each state.
- In a given clock cycle during operation, only one bit of the State Register is asserted.
- Only two bits toggle during a transition between two states.
