Abstract. Investigations of the efficiency of a microprogrammed finite-state machine with datapath of transitions in comparison with a canonical finite -state machine by the criterion of hardware expenses in the logical circuit of the finite-state machine are carried out. For the structures studied, the area of their efficient application is determined, which is expressed by a set of value ranges of finite-state machine parameters.

Keywords: microprogrammed finite-state machine, datapath of transitions, optimization of hardware expenses, area of efficient application.
