Heart-rate Monitoring System Design and Analysis Using a Nios II Soft-core Processor

Abstract

A person's heart rate can reveal their level of health. A heart-rate monitoring device, such as an electrocardiogram (ECG) or a photoplethysmogram (PPG), can measure or record a person's heart rate in real time. This study implements a microprocessor system that is loaded with a heart-rate monitoring algorithm. The Nios II microprocessor system communicates with a pulse sensor and an analog-to-digital converter (ADC). The microprocessor system measures heart rate using a beat-finding algorithm. The functionality of the microprocessor system loaded with the algorithm is examined through an experiment. The findings indicate that the observed heart rate falls within the range of the typical human heart rate. SignalTap II from Quartus' software is used to view and study the signal flow within the microprocessor system. The suggested microprocessor system has a total power dissipation of about 218.26 mW, according to a power analysis report.
