FPGA-based Train Onboard PCIe Board Design and Implementation

Since its introduction in 1992, PCI (Peripheral Component Interconnect) interface has been widely applied in various fields. In 2001, Intel launched the PCIe (Peripheral Component Interconnect Express) interface, which aimed to replace the old PCI, PCI-X (Peripheral Component Interconnect eXtended) and AGP (Accelerated Graphics Port) bus standards. PCI-Express interface features high speed and high bandwidth, which overcomes the bottlenecks of traditional PCI bus in system bandwidth and speed and demonstrates a promising application potential. By using FPGA (Field Programmable Gate Array) to design data transmission based on PCIe bus, the hardware design cost can be reduced, the integration can be improved, and the flexibility and adaptability of the design can be enhanced by using the programmable features of FPGA. In this paper, a transmission scheme of PCIe Hard IP Core and DMA (Direct Memory Access) IP Core based on Altera FPGA is implemented, and the design implementation and data transmission test are conducted.
