The quantity of communication is measured by counting the number of uses of the links between cells. In particular, iterative arrays are studied where the maximum number of communications per cell occurring in accepting computations is drastically bounded by a constant number. Additionally, the iterative arrays have to work in realtime. We study the computational capacity of such devices. One main result is that a strict and dense hierarchy with respect to the constant number of communications exists. Due to their very restricted communication, the question arises whether the usually studied decidability problems such as, for example, emptiness, finiteness, inclusion, or equivalence become decidable for such devices. However, by reduction of Hilbert’s tenth problem it can be shown that all such decidability questions remain undecidable. %G English %Z TC 1 %Z WG 1.5 %2 https://inria.hal.science/hal-02312607/document %2 https://inria.hal.science/hal-02312607/file/484947_1_En_3_Chapter.pdf %L hal-02312607 %U https://inria.hal.science/hal-02312607 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC1 %~ IFIP-WG1-5 %~ IFIP-AUTOMATA %~ IFIP-LNCS-11525
