基于DWC PCIE Core的数据传输系统设计OA

In the railway signaling system,a data sending and receiving system based on DWC PCIE Core is designed to reduce the CPU resource occupancy of railway signaling system.The system adopts FPGA development board suite embedded with ARM Cortex-A9 dual core,which takes the advantage of the flexibility and scalability of FPGA,and uses configurable PCIE hard core IP module and configurable Ethernet hard core IP module.This paper mainly introduces the realization of high-speed and reliable data transmission through PCIE bus and Ethernet based on DMA modules between Host PC and FPGA and between FPGA boards.
