In this paper, we introduce a new kind of automata systems, called
state-synchronized automata systems of degree n.
In general, they consists of n pushdown automata, referred to as their
components. These systems can perform a computation step provided that the
concatenation of the current states of all their components belongs to
a prescribed control language. As its main result, the paper demonstrates that
these systems characterize the family of recursively enumerable languages. In
fact, this characterization is demostrated in both deterministic and
nondeterministic versions of these systems. Restricting their components, these
systems provides less computational power.
