Abstract: In this paper is discussing definitions and procedures for parameters determination of systolic arrays (SA-s) which are suitable for regular 3-nested loop algorithms(this type of algorithm has calculations given by homogeneous linear relations in nested loops of index variables) implementation and between these especially defined special class so called adaptable algorithms. Namely, if we want to choose the most suitable SA for this adaptable algorithms, it is good to know their characteristics in advance, before their design and synthesis. In literature, we can find definitions of big number of space-time characteristics (objective functions) SA-s and their determination procedures and the authors choose his own procedure.
Objective of this paper is to consider one of time parameters, flow period of processor, in notation tp, and reciprocal dependency between time and space characteristics. Obtained results are illustrated trough the example of two rectangular matrix multiplication as one typical adaptable algorithm and especially its realization with one hexagonal SA for projection direction 
=[111]T which enables calculation of high dependability.
