Formal transition from algorithm to model for digital signal processing operations

Evolution of a basis of the organization of computing process for digital signal processing is observed. Necessity of the basis modification for parallel data processing is shown. Real transition to parallel data processing has made computation organization the object of the investigations. The object is characterized by set of variants of the computation organization. The variant chosen ought to provide efficient processing under the given conditions of computation realization. Therefore to provide a possibility of the well-founded choice of a variant of the computation organization it is necessary to develop a new formal basis of the organization of computations in the space-time domain. Formal model is the basis. The way of the formal model development is offered.
