Design and implement an electrocardiogram signal（ ECG） detecting system based on system on chip field programmable gate array（ So C FPGA）. ECG can be acquired and preprocessed by pre-acquisition amplifier circuit with high input impedance

high co-mode restrain ratio and low noise. Through design approach which combined hardware and software based on So C FPGA hardware platform and embedded Linux development environment

complete analog to digital conversion of ECG

VGA display

data storage in Micro SD card and ECG process with algorithms

wavelet analysis and QRS wave detection on ECG can be completed

realize acquisition

display

storage and processing of ECG.
