“…Let us point out that reducing power consumption, in our case, is not associated with additional overhead costs. The known methods in this area are connected to: (i) the representation of the initial FSM as a network of interacting automata (Chow et al, 1996;Liu et al, 2005), or (ii) the special state assignment (Benini and De Micheli, 1995;Benini et al, 2001;Agrawal et al, 2019), or (iii) the clock gating (Nag et al, 2018) or (iv) the power gating (Pradhan et al, 2011;Choudhury and Pradhan, 2012;Benini et al, 2000). We do not discuss these methods in detail.…”
