MOTIVATION
The problem chosen to design a portable and light weight device that is meant for continuous monitoring of human cardiac health without one’s involvement and record the data for future observation. This idea may be extended to wireless transmission of data for online purposes.
Project categorized into 3 modules:
Sampling 3 different signals: ECG, pulse and respiratory analog signals
Interfacing an SD card to DSP controller for recording all the above rates
Interfacing the whole system(this system should be a mobile device) to PC through USB for monitoring the data.
KEY COMPONENTS
TMS320C6748 DSP core
12 bit ADCs 3 numbers
SD card for data recording
USB host interface for viewing data from the PC
Signal processing instruments
Battery
LCD display and keypad(optional)
ADVANTAGES OVER ARM
Faster processing
More prone to real time applications
Dedicated for signal processing
Low power consumption
CHALLENGES
DSP resources are limited in the social media for reference
Fabrication and soldering is not possible manually
Functional correctness through simulation
Wavelet transforms for predicting transient responses
