Abstract: 
Organization of dataflow-controlled calculations for onboard real-time information processing is discussed. A subsystem was developed for designing microprogram modules (MPM) for the homogeneous computing medium (GCM). This subsystem includes also an imitator of the GCM A few samples of the MPM functional schemes are given. The method of paralleling algorithm for multiprocessor computing system was worked out on the basis of the dataflow properties The conditions for the onset of dataflow at a definite level of the level-parallel form are determined. The adjusting algorithm of flow activity multiprocessor system based on the homogeneous computing medium with the elements of optimization was developed and realized in a program form.
