To standardize and unify the source code and mathematical modeling of system software, it is advisable to use standard templates (patterns). They create a system software infrastructure for later use for program development. This is especially important for real-time operating systems, where you can pre-determine possible speed limits for embedded programs. For this purpose, for embedded systems based on microcontrollers of the Cortex-M architecture, standard software patterns State have been developed in the procedural and OOP paradigm. The developed patterns allow to unify the source code of the system software for microcontrollers of the Cortex-M architecture of different manufacturers. Research has been conducted to determine the speed limit of real-time operations. The software is adapted to the mathematical model of a finite state machine. The results were tested on microcontrollers of the STM32F1xx series. This allows to extend the solution to the MC of other manufacturers, which confirms the practical value of the developed patterns.
