Sequential and data flow models of processing

Abstract The concepts of a data flow and sequential computers are confronted using models written in the functional language Miranda. 1 A unified approach to both schemes of processing is presented together with an example of a simple problem, unsolvable sequentially, but easy for a data flow computer. Although these models have been designed to explain the concepts to students, they can be also used by researchers in comparative studies and general experiments. The model of a data flow machine seems to be especially useful, as hardware implementations are not widely available.
