Abstract: A design method of implementing the interface between ARM processor and the PCI bus was introduced based on FPGA.Not only does this method make the target circuit simple,flexible and efficient,but also can reduce the complexity of new design due to its reused code.Compliance test on many main boards which use Intel or AMD processor,and many different PCI reference devices showed that this design can meet the requirements and run stably.This method can be considered to implement the interface between all sor...
