Design of PCI Bus Interface Based on FPGA

Aimming at the problems of the application limitation of traditional PCI interface controller,an improved design scheme of PCI bus interface based on FPGA is proposed.The function modules of PCI bus interface are introduced,the state machine structure and the working process of master and slaver interface are mainly introduced.The hardware design of PCI function is simulated by ModelSim software.The simulation result shows that the interface is adapted to 32-bit or 64-bit PCI devices,and fulfils the timing requirements of the PCI bus.
