| Abstract: | When PCIE is used for interconnection of devices,the interface logic is needed for interaction between the bus and internal function.This paper adopted a method based on IP core,and completed the designing and implementation of the interface logic in Xilinx Virtex-7 series FPGA.Then the function and performance was verified.The results showed that registers accessing and data transfer in DMA mode were correctly and the bandwidth of DMA transmission was more than 70%. |
