To realize real?time control of servo system′s angle position,a high?speed angle position data acquisition system based on PCI IPcore is designed in this paper. The PCI interface logic,FIFO memory cell and axial angle converting control logic are realized with FPGA. A resolver?to?digital converter is adopted to realize the high?speed axial angle conversion. In addition,a corresponding driver of windows driver model(WDM)is designed. The acquisition card is applied to LabWindows system. Exper?iments prove that the max sampling rate is up to 27 r/s,and the data transmission rate achieves 132 MB/s.
