Exploring Efficiency: Comparative Study of Microcontroller Energy Consumption and Performance Optimization Strategies

Abstract

This study presents a comparative analysis of energy consumption and performance characteristics across varying operating scenarios of prominent microcontrollers. Specifically, the impact of processor clock frequency and sampling frequency on energy efficiency and system performance in embedded applications is explored. Findings reveal insights into the trade-offs between energy consumption, average power usage, and processing time associated with different frequencies. Higher frequencies generally lead to reduced execution time and energy consumption, with variations among the microcontrollers. These insights inform decision-making processes for optimizing power usage and system design, highlighting the importance of selecting appropriate frequencies to achieve desired performance metrics while maintaining energy efficiency. Additionally, the study examines the impact of time intervals (tcycle) on energy consumption behavior, revealing distinct patterns among microcontrollers. Comparisons of voltage range, frequency range, and energy consumption figures underscore the significance of these specifications in selecting microcontrollers tailored to specific application requirements, aiding in the development of energy-efficient embedded systems and IoT devices.
