針對基于小波變換的心電信號QRS波的檢測算法的計算量較大，硬件不易實現的問題，提出一種FPGA的實現方案。首先分析了利用小波變換檢測QRS波群的算法，給出硬件實現方案，該算法由小波變換模塊和檢測模塊兩個模塊實現。然后選取高端FPGA作為硬件處理平臺，給出小波變換模塊及波形檢測模塊具體實現結構。最后在QuartusⅡ下進行編譯和仿真，完成心電信號檢測算法的硬件實現。從綜合后的資源占有率上可以看出系統充分利用了FPGA內部豐富的資源，從仿真的結果看出在FPGA系統上準確的檢測出了QRS波。

Abstract:: ?A FPGA design and implementation scheme is proposed according to the problems of the ECG QRS wave detection algorithm based on wavelet transform’s large computation and it’s hardware is not easy to achieve. Firstly，through analysis of QRS wave detection based on wavelet transform algorithm，a sheme for hardware implementation is put forward. This algorithm is achieved by wavelet transform module and detection module. Then，high performance FPGA is selected as hardware processing platform and architecture of the wavelet transform module and detection module are proposed.Finally，the compilation and simulation were made under QuartusⅡ，and the hardward implementation of the detection algorithm of ECG is achieved. The rate of resource occupancy shows that the resourceful propertiy in FPGA is greatly utilitzed by the scheme and the results of simulation show that QRS wave is detected accurately in FPGA system.
