The work is devoted to the estimation of resource consumption of the microcontroller for the synthesis of bar graph discrete-analog data display on the LED information field in bicyclic mode. The paper compares the programs of multicycle information output and its bicyclic analogue for discrete-analog means for the information display systems. The significance of the influence of bicyclic information models on the minimization of machine time resources of a single-chip microcontroller is shown. It is determined that in order to reduce resource consumption in the developed solutions it is necessary to focus on the maximum possible optimization of program blocks that are executed during interrupts and serve the I / O subsystem of the microcontroller. In this sense the bar graph displays based on the bicyclic additive information model has the best results. It was found that the traditional approach to assessing the effectiveness of programs using special benchmark programs, with subsequent measurement of code and execution time of the entire program does not allow to correctly assess the effectiveness of the program and the work of microcontroller at the device design stage. Therefore, as an alternative, it was proposed to use the size of the bytecode of the program and the speed of the main cycle - the procedure of information output to assess the effectiveness of the program. It was found that in terms of speed of execution and consumption of resources, the multicycle version significantly loses to the bicyclic program. Also, reducing the number of image formation cycles in the information field is one of the most effective way to minimize the consumption of microcontroller resources for display services.
