Abstract
Department of BACKGROUND: Signal processing method based on Field Programmable Gate Array (FPGA) integrates the advantages of
Medical Information,
Sichuan University, Software algorithm and ASIC, applying to digital signal processing field in place of ASIC and microcontroller gradually.
Chengdu 610065, OBJECTIVE: To propose an acquisition system based on FPGA, which can acquire ECG and heart sounds simultaneously,
Sichuan Province, actualize ECG and phonocardiogram to display on LCD in real-time, play heart sounds synchronously to offer a diagnosable
China method bined auscultation with check phonocardiogram and ECG.
METHODS:
Nie Wen-zhong★, The hardware system with FPGA embedded soft core as the core used the VHDL to realize structured design and
Studying for master’pleted real-time collection of ECG and heart sounds, data processing, data transfer and display.
degree, Department RESULTS AND CONCLUSION: Compared with microcontroller-based acquiring system, this system plexity of
of Medical peripherals circuit and improves integ
