This paper is about development of Non-invasive Heart rate and Oxygen saturation in Human blood using Altera NIOS II soft-core processor system. In today's world the Monitoring oxygen saturation and Heart rate is very important in hospitals to keep track of low oxygen levels in blood and Heart rate. We have designed an Embedded System On Peripheral Chip (SOPC) reconfigurable system by interfacing two wavelengths of light using two LED’s (660nm/940nm) with a single photo-detector to measure the absorptions of haemoglobin species at different wavelengths. The implementation of the interface with Finger Probe and Liquid Crystal Display (LCD) was carried out using NIOS II soft-core system running on Altera NANO DE0 board having target as Cyclone IVE. This designed system is used to monitor Oxygen Saturation in Blood and Heart rate for different test subjects. The designed NIOS II processor based Non-invasive Heart rate and Oxygen saturation was verified with another Operon Pulse oximeter for 50 measurements on 10 different subjects. It was found that the readings taken were very close to the Operon Pulse oximeter.
