Multiprocessor automata. (English) Zbl 0653.68044

The notion of multiprocessor automata is introduced. The multiprocessor automaton may be thought of as the simplest model of parallel computations: there are more than one processors reading information from the tape simultaneously, and the switching function for each processor depends on the inner states of all processors on the step of computations. We prove some results on the hierarchies of two-way and one-way multiprocessor automata languages.
