Abstract
This paper is concerned with the functional distributed architectures (FDA) performance. In this work a quantitative analysis of FDA performance has been carried out. The carried out analysis makes it possible to determine the limits for the effective usage of FDA structures. The formulae for the speedup of the computations at the FDA structures have been obtained. The formulae for determining the maximum number of executive processors which allows us to achieve the greatest computation's speedup at the given FDA structure have also been obtained. It is shown that use of the executive processors with communication autonomy allows us to introduce the additional levels of the instruction's interpretation, due to which the bus traffic is reduced. A quantitative evaluation of this fact is presented in the paper. Keywords: functional distributed architecture, control and executive processor, cyclic interleaved computations, speedup, macrooperation, one/two-level instruction's interpretation.S. Zaporojan,
