Abstract:

BACKGROUND: Signal processing method based on Field Programmable Gate Array (FPGA) integrates the advantages of Software algorithm and ASIC, applying to digital signal processing field in place of ASIC and microcontroller gradually.
OBJECTIVE: To propose an acquisition system based on FPGA, which can acquire ECG and heart sounds simultaneously, actualize ECG and phonocardiogram to display on LCD in real-time, play heart sounds synchronously to offer a diagnosable method that combined auscultation with check phonocardiogram and ECG.
METHODS: The hardware system with FPGA embedded soft core as the core used the VHDL to realize structured design and completed real-time collection of ECG and heart sounds, data processing, data transfer and display.
RESULTS AND CONCLUSION: Compared with microcontroller-based acquiring system, this system simplifies complexity of peripherals circuit and improves integration and performance of the system.
