基于FPGA的脉搏信号采集系统设计

介绍了一种人体脉搏信号的采集系统,通过专用的脉搏传感器采集信号,将得到的信号经过预处理后送到FPGA,暂存到RAM中,同时用FPGA驱动VGA接口实时显示脉搏波形。利用FPGA的片内资源RAM实现了脉搏波形图像的动态显示,实时性好、画面清晰,为后续的生理病理信息提取提供了有效支持。

Pulse signal acquisition system design based on FPGA

In this work, a human pulse signal acquisition system is designed. Firstly, the pulse signal is collected by a specificsensor. After preprocessing, the signal is sent to FPGA and stored into the RAM buffer. In the meantime, FPGA drives VGAinterface to display the pulse waveform in real time. Fully utilized the on-chip RAM of FPGA, this system can display the dynamicdata of pulse waveform in real time with high quality. It can provide effective support for the subsequent extraction of physiologicaland pathological information.
