| Description |
An onboard computer is a specialized computer system integrated into a vehicle or, in general, another complex technical device that requires autonomous control and high reliability. The objective of this research is to investigate the reactivity of the FreeRTOS operating system in the energy-saving mode of an onboard computer microcontroller. The subject of this research are the methods, tools, and technologies used in the experimental study of the reactivity of the FreeRTOS operating system. The aim of this work is to develop a technology for conducting experimental studies on the reactivity and power consumption of computing platforms. Tasks: to analyze real-time systems and typical scheduling algorithms; to review existing methods for evaluating the performance and energy efficiency of microcontrollers of on-board computers; to plan an experiment to study the reactivity and energy consumption of the computing platform; based on the results of the experiment, to analyze the author's platform according to the specified criteria. Conclusions. This paper presents an experimental assessment of the reactivity and power consumption of the “Falco/Boryviter” computing platform developed by the authors. The proposed platform was implemented on the Cortex-M7 - ATSAMV71 microprocessor and runs on the open-source real-time operating system FreeRTOS. The experimental results confirmed that the developed microcontroller platform is effective and makes it possible to build control systems with predictable reactivity and acceptable energy costs. The proposed platform can be adapted for tasks with a rapidly changing computational context under the influence of external factors. The disadvantage of this work is the lack of verification of the developed technology through experimental studies for the Sleep, Wait, and Backup modes of the ATSAMV71 microprocessor.
