| Abstract: | To fit the increasing demand for high-speed data acquisition and remote transfer,the paper introduces a high-speed fiber card based on PCI Express bus.The card is realized by a Virtex-5 FPGA chip.It uses PCI Express bus at endpoint,takes LocalLink as internal link interface,and realizes remote fiber transfer on Aurora protocol.By the DMA control of PCI Express,the card can reach a speed of 700 Mb/s. |
