This paper briefly introduced the characteristic values extracted from the photoplethysmography contributed to analyze people’s pathological features in the field of medicine.In order to detect the blood parameter of the pulse wave,the whole system which is based on the development platform of Altera company’s cyclone series used hardware language Verilog HDL to program into FPGA to design the block of waveform parameter detect and through the design of IP core conducting data processing and also realized the real-time detect of pulse wave.The project using QuartusⅡ,Icarus verilog and GTKwave software to conduct the synthesizing and simulation and through the FPGA prototyping.Innovation of this design is that FPGA is used as the hardware way to increase speed of the real-time detect,reduce development costs and enhance portability.%文章简要介绍了从光电容积脉搏波中提取出的特征值有助于在医学领域中分析人体的病理特征。为了检测脉搏波的血流参数,整个系统采用Altera公司cyclone系列的FPGA开发平台,运用硬件语言Verilog HDL编程设计了波形参数的检测模块,通过设计IP核进行数据处理并实现了脉搏波的实时检测。使用了QuartusⅡ、Icarus verilog和GTKwave软件进行综合仿真,并通过FPGA原型验证。创新点在于采用FPGA通过硬件的方式提高了实时检测的速度,降低了开发成本,增强了可携带性。
