Дослідження ефективності реалізації цифрових фільтрів на ESP32

Abstract

The work analyzes the usage of digital filters in electronic devices. The problem of assessing the speed of digital filters implementation on the popular ESP32 platform is formulated. 3 digital FIR filters were synthesized, a filtering algorithm using cyclic buffers and a DMA controller was created and studied. The developed algorithm has been proven to have a 12-times acceleration in the ESP-IDF environment compared to the classic implementation in the Arduino IDE. The ESP32 hardware platform has been proven to be highly effective for the practical implementation of digital filters.
