Computational Performance Of Arm Cortex M4 Andm7 Microcontroller On Motor Control Application

Abstract

The paper is focused on a comparison of three microcontrollers from computational performance point of the view. The comparison is performed on motor control and fault detection algorithm code executed from microcontroller internal FLASH memory. This code contains more complicated mathematical functions. The computational performance is compared according to computational time on STM32F4, STM32F7 and SAM E70 microcontrollers. Another aspects (like core clock frequency, FLASH configuration, cache configuration, etc.) of microcontroller settings are taken into account in experimental results.
