Abstract

The problem of minimizing power consumption during the state encoding of a finite state machine is considered. A new power cost model for state encoding is proposed and encoding techniques that minimize this power cost for two- and multi-level logic implementations are described. These techniques are compared with those which minimize area or the switching activity at the present state bits. Experimental results show significant improvements.
