Some dangers in state reduction of sequential machines
In this paper we investigate the negative effects of state reduction on the realization of a sequential machine. It is shown that state reduction can destroy realizations of a given sequential machine from sets of smaller machines and thus lead to a sequential machine that is harder to realize. To u...

Summary: | In this paper we investigate the negative effects of state reduction on the realization of a sequential machine. It is shown that state reduction can destroy realizations of a given sequential machine from sets of smaller machines and thus lead to a sequential machine that is harder to realize.
To understand some of the reasons why and when state reduction should be carried out, several results are obtained which describe the changes of the structure of a sequential machine under state reduction. It is seen that the undesirable effects of state reduction are closely associated with the failure of certain distributive laws to hold between the partitions used for state reduction and the partitions used in the realization of the unreduced machine. |
