Design of PCI Bus Interface Based on FPGA

PCI bus was widely used in data acquisition and processing system because of its outstanding capability.It's more freedom to design PCI interface based on FPGA relative to using special PCI interface chip.In order to realize a simply PCI Target interface on FPGA,building block design method was introduced.The PCI interface logic was divided into four modules.And the designing of state-machine module was emphatic introduced.Then,the simulation waves of memory read operation was given.The result indicated that it is accord with PCI Specification.Now this design was tested in underground detecting radar system.
