Abstract:

PCI Express is a high performance interconnect protocol is widely used in many areas of the network adapter,graphics accelerator,network storage,and large data transfer in embedded systems.This paper describes the architecture of PCIe,and highlights the use of Altera Cyclone IV GX FPGA family to achieve hardware PCIe interface card parameters involved,the application layer system solutions,DMA arbitration,and PCIe hard-core configuration with read and write timing.

Key words: PCI Express;Cyclone IV GX FPGA;DMA arbitration
