Abstract. The problem of scheduling processor loading in multiprocessor systems of critical purpose is con-sidered. The proposed method of the load planning is focused on hardware realization in connection with impossibility of application of software. A specialized device for the load planning is developed; functional scheme of the device is described, analysis of its hardware and time complexity is presented. By summing up the execution time of operations by the elements of the device, taking into account the increase in the possible number of processors in the system, a dependency diagram is obtained. Analysis of the diagram allows to conclude that the operating time of the processor load planning device grows exponentially with the number of processors in the multiprocessor system, i.e. with the increase in the size of the load queue.
Keywords: multiprocessor system, critical system, processor, schedule, load plan, algorithm, functional scheme
