Aim\ To study the design of interface circuit on using FPGA to implement data exchange with PCI interface chip. Methods\ The PCI protocol and AMCC S5933 have been analyzed. VHDL is used to design the interface circuit and EDA software and FPGA are used to implement it. Results\ A communciation scheme and concrete implement between FPGA and S5933 is established. Conclusion\ It can implement data exchange between FPGA and S5933
which resolves the problem on designing of PCI equipments.
