摘要
为了实现数据采集存储设备产生的高速、大容量地数据能够快速、可靠、远距离地实时传输,提出了以PXI系统为平台,采用单一周期和线性突发模式相结合的总线访问方式,以PCI9054作为"桥接"芯片,高速FPGA为微控制器,结合LVDS及高速光纤传输技术的总体方案设计;经实践测试,传输数据正确可靠,实现了177Mbps长距离通信速率。
For the purpose to realize high--speed , storage of huge data generated by stored acquisition device real--time transmission fast and relia- bly over a long distance , a scheme is proposed to solve this problem , which adopted the new bus access combining single cycles with burst mode , used PXI system as the platform, PCI9054 as the ＂bridge＂ chip and high--speed FPGA as micro controllers and combined LVDS with high--speed optical fiber transmission technology. The result is to achieve the rate at 177Mbps with accuracy by means of practical test.
