Explain the role played by transition probabilities and state encoding in determining the power dissipation of finite state machines

Solution

power dissipation by sequential circuits by choosing state assignment which minimizes the switching activity between state transitions. Thus the combinational part of FSM has lower input transition probability and is more like to give low power dissipation when synthesized. This algorithm uses boolean matrix with rows corresponding to state codes and column corresponding to state variables. Single state variable is considered at a time and try to assign its value to each state in FSM, in a way which is likely to minimize the switching activity for the complete assignment. This procedure is repeated for the next variable. Since minimization technique is applied column by column this technique is called as Column based
