This document describes a project to design a heart beat monitor using an optical finger tip sensor and FPGA. The objectives are to detect heartbeats without needing to visit a doctor. An introduction explains how medical devices like ECGs are commonly used but cannot be used independently by patients. The document outlines that an FPGA will be used due to benefits like reprogrammability. It provides details on the Spartan 3e FPGA and includes a block diagram of the hardware design. The design will use an IR LED and optical sensor to detect heartbeats, which will be conditioned and sent to the FPGA for processing. A flow chart shows the timing and counting logic. A timeline is provided for completing literature review, coding

3. Objective
In this project a device which can detect the
heart beat will be designed using an optical
finger tip sensor and implemented on to the
FPGA (Field Programmable Gate Array). .

4. Introduction
 Now a days, the scope of the medical field
has exponentially risen over the decades.
Senior citizens have to make frequent
visits to their doctors for their regularly
check up and get their vital measured.

5.  One of the medical instrument that is
used for the examination of the heart is
Electrocardiograph (ECG).
 ECG can not be used independently by
patients to detect their heart health but
by this system can check their vital sign
without the help of the doctor.

6. FPGA
 FPGA is a programmable device that is
composed of large modules independent
logic that can be configured by the user
who is connecting through the canals of
programmable routing.

7. NEED FOR FPGA
 Performance
 Time to Market
 Cost
 Long-Term Maintenance
 Reprogrammable logic or reusablity
